Why a compressor room needs to stay cool!

Author: David J. Connaughton
Blog: Compressed Air the Fourth Utility

Compressors are often put into small rooms to reduce noise. Unfortunately, putting a compressor inside a small room creates problems. One of these problems is heat. Compressors create a lot of heat from the compression of the air. This heat is usually expelled into the room via a fan cooled aftercooler. It’s not unusual to find temperatures well above 100F (38C) regardless of the temperature outside.

About 20 years ago I was using a computer to collect data on an experiment that I was conducting inside a compressor room. I was having trouble with my computer. It seemed to freeze in the middle of my experiment and not collect the data through the full experimental run. I took it out of the compressor room, back up to my lab to trouble shoot. No matter what I did, I could not duplicate the error in my lab. I even brought the computer to the local repair shop and they could not duplicate the error either. So I brought the computer back to the compressor room and started collecting data again. But again, the computer froze up. What was going on? It turned out that the temperature inside the compressor room was so hot that the electronics inside the computer we affected. My solution was to place the computer outside the room and run lines through the wall to the experiment. Problem solved.

Heat in the compressor room has a direct effect on the quality of the compressed air in your air system. The hot room attracts moisture from the surrounding environment since hot air holds more moisture than cold air. The room acts like a sponge soaking up all the moisture surrounding the room. This moisture finds its way into the compressed air lines creating condensation and contamination. High temperatures also create finer mists of any oil carryover. Finer mists and aerosols are stable at high temperatures and have the ability therefore to bypass filtration in the compressor room and contaminate the piping system downstream.

To minimize the effects of heat inside a compressor room, you’ve got to cool it down. Fresh air circulation is key. In the summer time, air should be expelled from the room and draw in air from outside. In the winter-time, the hot air created by the compressor can be blown into the workplace for supplemental heating. Don’t just put your compressor in a room and forget about it. If you keep it maintained and keep it ventilated your whole system will perform better.

Parker Balston Filters and dryers do a great job of cleaning up the compressed air at the point of use.

    GPI Flow Meter LCD Display Explained

    Posted in: Industrial Flow Meter Articles: Liquid Flow Meters by GPI on 7/8/2010
    If you are familiar with our GPI flow meter brand you probably know or have experience with our electronic digital flow meter display. We believe that our flow meter display is one of the better ones out on the market today. In this post we will explore what we call the “new” GPI 9 LCD electronic display that is being shipped with our TM Series Water Meters, G2 Series Industrial Grade Flow Meters and our A1 Series Flow Meters.  We hope that by the end of this post you will be familiar with some of the basics of this flow meter display and have a better understanding on how it works with our flow meters.

    What does the “new” GPI 9 flowmeter display do?
    Allows you to measure batch & cumulative flow totals
    The GPI 9 flowmeter electronic display gives you two totals, one for batching a set amount of liquid that you can reset and the other is a cumulative total that can’t be reset. An easy way to understand these two totals is if you think of the batch total as your trip meter in your car. The trip meter allows you to see how many miles you have traveled with the ability to reset it whenever you see fit. That is the same thing the batch total option on this flowmeter display does, it allows you to measure an amount of liquid with the ability to reset it at anytime. The way to remember how the cumulative total works is if you think of your car’s odometer. The odometer measures how many miles the car has traveled but you can’t reset it. The cumulative total option on this display measures the same way as the odometer, total gallons or litres that the meter has measured in its lifetime use.

    Measures Flow Rate 
    The GPI 9 flow meter display allows you to measure the flow rate of liquid being measured. The flow rate is typically measured in gallons or litres per minute (GPM or LPM). This new display allows you to measure in units per minute, units per hour and units per day. If you need to measure how much water your applications has running through it per hour all you have to do is hit a couple of buttons and the display will change from measuring gallons per minute to gallons per hour. The flow rate is like your speedometer in your car, it tells you the speed that your liquid is traveling through your line or application. This feature is good if you are monitoring how fast or slow your liquid passes through your pipes.

    Non-Volatile Totals = No Data Loss
    If you have ever used one of these displays in the past you would have noticed that when you replaced your batteries the totals zeroed out. In this new configuration of the GPI 9 display, when you change your batteries your totals will still be available once the meter is powered back on. This is also a great feature if you install your flow meter in a remote area that you only check on every now and then. If the meter display happens to lose battery power by the time you get a chance to check it, you can rest assured that once you put new batteries on the display your totals will still be available for you to see.

    5 Year Battery Life = Display Doesn’t Turn Off
    If you have purchased one of these new displays you might have noticed that the display never shuts off. The main reason that this happens is because of the Lithium battery life of five-years. We used to send flow meters that had this display with a battery tab installed that needed to be pulled in order for the display to turn on. This display has a five year battery life regardless of whether it is on or off. The power that this display draws is very small therefore it affords for a long lasting battery life.

    Easy-To-Use Correction Factor Method
    The new display allows you to calibrate your meter by inputting the plus/minus correction factor. You may want to custom calibrate the meter after testing using your actual fluid conditions. You can field calibrate the meter by using the buttons to enter the percent of change you want the display to correct. Values from -99.99% to +99.99% can be entered.

    Various Factory Calibration Units Available
    This flow meter display’s standard factory calibration is in gallons and litres. However, the display can be configured to read in imperial gallons, quarts, ounces, cubic feet, cubic centimeters, cubic meters or barrels.

    Ability to Count Past 999,999
    In past versions of this display you were only able to read flow rates up to 999,999 because of the six-digit allowance on the display. This new flow meter display will illuminate a X10 on the top right once you have gone past 999,999. This gives you the ability to know that you are at 1,000,000 and above. If you go past 999,999 X10 then the meter will go back to 100,000 and a X100 will be illuminated on the top right corner instead of X10.

    What are the differences between this flow meter display and the previous version?
    • Gallons read GL instead of GAL.
    • Litres read LT instead of LTR.
    • Flow Rate displays as FLOWRATE/M instead of FLOWRATE. The M at the end of FLOWRATE means gallons or litres per minute depending on how you have the display set to reading. This can also be switched to read FLOWRATE/H to measure per hour or FLOWRATE/D to measure per day, with the exception of the TM series meters.
    • Top right side of the meter reads FAC instead of PRESET. If these three letters are showing it means that the display is being used under the factory calibration. If you custom calibrate it for your specific liquid the FAC will not show. This will help you know in what calibration mode you are under.
    • TOTAL 1 doesn’t say locked but know that this is the cumulative total and you can’t zero it out.
    • TOTAL 2 says BATCH next to it indicating that this is the total you should be on if you want to run batches at a time.
    • The numbers are wider therefore making it easier to read.
    • The display will not shut-off

    Differential Pressure: A Difference You Can See

    Differential pressure gauges are often found in industrial process systems and yet, they are easily overlooked or misunderstood. In fact, a differential pressure gauge can often times provide multiple solutions to everyday problems.

    Differential pressure (DP or ∆p) is the difference between two applied pressures. For example, the pressure at point “A” equals 100psi and the pressure at point “B” equals 60psi. The differential pressure is 40psi (100psi – 60psi).

    A differential pressure gauge is a visual indicator, designed to measure and display the difference in pressure between two pressure points in a process system. They typically have two inlet ports, each connected to the pressure points that are being monitored. In effect, the differential pressure gauge performs the mathematical operation of subtraction through mechanical means. This eliminates the need for an operator or control system to watch two separate gauges and determine the difference in readings.

    Typical applications for differential pressure gauges in refineries, petrochemical or chemical plants include filter monitoring, liquid level measurement and flow measurement.

    Filter Monitoring
    Filtration is a vital part of an efficient operation in industrial process systems. A differential pressure gauge can be used to detect a contaminated or clogged filter. As the filter collects foreign materials, the pressure before the filter builds up. The Differential pressure gauge measures the pressure before and after the filter. The more the filter gets clogged with particles, the more the differential pressure increases. Once the differential pressure reaches a maximum value, then the operator knows that the filter needs to be changed.

    Liquid Level Monitoring

    Sealed tanks often have an atmospheric pressure gas blanket on top of the contained liquid. The pressure of the gas blanket adds to the hydrostatic pressure created by the water column of the content. This makes it difficult to get an accurate level measurement using a conventional pressure gauge. A differential pressure gauge measures the difference in gas pressure from the total pressure, thus translating into a true liquid level reading. Differential pressure gauges can also be used on production and injection wells to measure the difference between reservoir pressure and bottom-hole pressure, or between injection pressure and average reservoir pressure.

     Flow Monitoring
    Differential pressure gauges are also used to measure the flow of a liquid inside a pipe. Utilizing an orifice plate, venturi, or flow nozzle to reduce the diameter inside a pipe; the differential pressure gauge measures the pressure before and after the orifice. The pressure drop across the orifice is then mechanically translated by the differential pressure gauge into the flow rate. Differential pressure gauges are an uncomplicated solution for a visual indicator when measuring process flow.

    Why WIKA
    WIKA Instrument Corporation offers a wide variety of differential pressure gauges that are best suited for industrial processing applications. WIKA's differential pressure gauges offer an assortment of housing materials, wetted parts, dial sizes, connection types, mounting configurations, and custom dial art work. Design options include: piston-style, dual diaphragm and the all-welded/all stainless steel models.

    Piston-style differential pressure gauges (Wika Type 700.04) are designed for a long service life. The piston-style differential pressure gauges are best suited for use with clean liquid or gaseous media where low differential pressure ranges and static working pressures are required. Piston-style differential pressure gauges are also available with a separating diaphragm (Wika Type 700.05) for applications that do not tolerate a flow-by, such as liquid level applications. Both feature a 7 year limited warranty.

    Dual diaphragm differential pressure gauges are ideal for applications requiring high working pressure in combination with very low differential pressure. The pressurized components are mounted outside the case and face plate for maximum safety. Dual diaphragm differential pressure gauges feature an all stainless steel construction with 316 wetted parts. These gauges are suitable for high working pressures up to 3600 psi regardless of scale range.

    The all-welded/all stainless steel construction model (Wika Type 732.51) is best suited for applications with corrosive atmospheres or media, pressure pulsation, system vibration, wide range of ambient temperatures, or high media temperatures.

    Don't overlook where a difference can be seen. WIKA Instrument Corporation's differential pressure gauges are available in an assortment of styles, designs, and solutions that are perfect for industrial process systems.

    Safety Critical Protection Systems: Implementing Pressure Sensor Signal Redundancy to Lower Costs

    Written By: Jürgen Reiser, Product Manager, Electronic Pressure Measurement, WIKA Alexander Wiegand GmbH & Co. KG, Germany and Martin Armson, Director of Electronic Pressure Measurement, WIKA Instrument Corporation, USA

    In today’s world, safe working conditions are increasingly mandated by legislation and voluntary codes of practice. Automated load monitoring systems using pressure transmitters are becoming instrumental in creating safe working environments. They play an important part in making certain that machine control systems used in utility vehicles including cranes, lifting platforms and fork-lift trucks perform with precision, accuracy, and most importantly reliability. ‘Failsafe’ is the keyword that drives system designers to be ever more creative. System redundancy is a design concept that helps meet these regulatory requirements. Pressure transmitter based systems must guarantee that systematic failures within hydraulic controls are eliminated and random error functions are identified so that all moving parts are shut down if a dangerous condition exists.

    In typical load and load-moment monitoring applications, pressure is measured at the hydraulic cylinder of the boom, the hydraulic pump of the traction drive, or at the pressure reservoir of the brake system. Any malfunction of a pressure transmitter may lead to a critical condition of the system. A malfunction may be caused by extreme environmental conditions (EMC, humidity, shock and vibration, or physical damage). It can also be caused by abnormal operating conditions including an overload of the pressure sensor caused by pressure spikes. Erratic software failures in the subsystem program or a defective electronic component may also be a source of an incorrect pressure transmitter and/or system output signal.

    Machine designers take many preventative steps to provide a continuously safe operating condition. One easy, practical, and common solution is to use two pressure sensors at the same measurement point. A redundancy check of the two output signals is made in the machine logic control circuit to detect any unexpected deviation in pressure transmitter readings.

    The disadvantages of this approach are that an additional pressure port with separate sealing is required, as are additional electrical connectors with mating connectors. A larger number of electrical components are required to use two individual pressure sensors. From a safety standpoint, this increased complexity presents additional opportunities for failure.

    The WIKA Answer: ‘2 in 1‘ Pressure Sensor MHS-1

    WIKA’s MHS-1 pressure transmitter offers the first integrated dual pressure sensors, manufactured specifically for safety- critical and safety-related applications in mobile hydraulics. Dual (2 channel) pressure measurement, separate electrical signal processing and two independent 4-20mA output signals enable control-side redundant monitoring for pressure measurement points.

    It is now possible for Channel 1 to be a pressure sensor with measuring range 0-3000 PSI with a 4-20mA proportional electrical output signal and for Channel 2 to be 0-5000PSI for 4-20mA. Note: the pressure sensor with the smaller measurement range is selected for the maximum possible system pressure as both pressure sensors have only a single mechanical process connection. The use of identical pressure ranges or a reverse scaling of the second signal to 20-4 mA is also possible.

    A random hardware or software error of the safety-critical load monitoring system can be detected by monitoring the dual pressure sensors in the control system, and the actuator can be set to a safe condition if a hazardous condition is detected. Therefore, the probability of a dangerous failure is substantially reduced. This solution increases the process security and is cost effective since the mechanical and electrical installation costs are clearly lower than installing two individual pressure sensors.

    TÜV certified Safety
    The MHS-1 is designed to meet both the ISO 13849-1 (performance level - PL) and IEC 61508 (Safety Integrity Level - SIL) safety standards. It is certified by TÜV, a recognized and independent test laboratory. The requirements of the new European Machinery Directive (2006/42/EC), which becomes mandatory in Europe at the end of 2009, have already been met.

    Safety-related characteristics available from WIKA for the pressure sensor include, “Mean Time to Failure” – (MTTF values). A complete safety-related control system can be evaluated by the user quickly and easily. The MHS-1 achieves the Safety Integrity Level SIL 2 in accordance with IEC 61508 and safety category 3 Performance Level d in accordance with ISO 13849-1.

    Robust Design for demanding environmental conditions
    WIKA‘s hermetically-sealed, welded, dry thin-film measuring cell with its sputtered Wheatstone bridge offers long-term stability in applications with high dynamic load changes. Thin-film sensors feature excellent resistance to pressure spikes. In addition, an arc eroded pressure port and cavitation damping system integral to the process connection minimizes the possibility of pressure sensor failure. The electronics are designed for harsh EMC conditions up to 100 V/m. The robust stainless steel housing and the IP 69K high pressure steam washdown rated electrical connection are designed and extensively tested for the extreme conditions often encountered in mobile hydraulics.

    Customer-specific Designs
    WIKA has various safety-evaluated designs available for a variety of applications both with and without sensory overload detection. WIKA’s flexible instrument assembly and modern production system supports custom designs.

    Installing the Wrong Pressure Transmitter Can be Dangerous

    Author: Wika Application Notes

    Whether it’s protecting human life, protection of expensive equipment, or meeting installation codes, safety is the number one concern when working in hazardous areas when there is a concentration of flammable gases, vapors or dust. Many pressure transmitter users in petrochemical, chemical, or refineries are unaware of the potential dangers of selecting the wrong pressure transmitter for their application. Using the correct pressure transmitter can mean the difference between causing and preventing a fire or explosion.

    A non-rated pressure transmitter can create severe safety issues for both equipment and employees. Improper installation or use may damage the pressure transmitter making it a possible ignition source.

    To help alleviate this concern, hazardous area pressure transmitters minimize these potential safety hazards. They are available in a variety of designs and approval ratings including explosion proof, non-incendive and intrinsically safe.

    Hazardous Area Pressure Transmitters
    Explosion-Proof pressure transmitters are based on the theory of containment and are designed for applications requiring Class 1, Division I approvals. These pressure transmitters are designed to contain, control, cool and vent any possible ignition, without igniting the surrounding flammable gases or vapors. They require installation with conduit and seal offs to maintain the explosion proof rating.

    Non-Incendive explosion-proof pressure transmitters are preferred when potential hazards are only occasionally present. They are designed to work in Class 1, Division II hazardous areas and require less stringent installation procedures than explosion-proof pressure transmitters.

    Intrinsically Safe explosion-proof pressure transmitters are designed to limit the thermal and electrical energy to a point where ignition is not possible. Intrinsically safe pressure transmitters require the use of an intrinsically safe barrier installed in the safe area. They do not require the use of conduit and conduit seals or need a “hot permit” if servicing of the instrument loop is required. This technology is standard in Europe and is becoming increasingly more popular in the United States.

    Why Wika
    Over the last six decades, WIKA Instrument Corporation has become a symbol for sophisticated solutions in the field of pressure and temperature measurement.

    WIKA’s family of hazardous area pressure transmitters is suitable when applications do not require the full functionality of smart pressure transmitters. WIKA’s E-10, N-10 and IS-20 pressure transmitters all feature technology designed for use in hazardous locations. Features include pressure ranges of 30inHg vacuum to 15,000 psi; output signals of 4-20mA to 1-5v; and a variety of approvals. All are backed by a two year warranty.

    Ways to Prevent Pressure Gauge Failure

    Author: Wika

    There are many products and services that can prevent pressure gauges from failing. Gauge audits and Best Practice Instrument Reviews are the best first line of defense. These reviews and audits will tell you which instruments are properly functioning and which ones should be replaced. There is a review of the gauges currently installed, gauges installed demonstrating unwanted conditions and of gauges installed demonstrating best practice. This review is provided by the team at the end of the review. Gauge audits and instrument reviews can be conducted to show and prevent mishandling and improper use of gauges.

    A second line of defense could be to add a product or accessory to the configuration to alleviate the pressure or temperature. There are many products and services that can prevent pressure gauges from failing:
    • Mechanical vibration can be avoided by choosing the correct pressure gauge for the application. Depending on the application a liquid filled gauge might be needed over a dry gauge.
    • Pressure gauge snubbers avoid pulsation by absorbing pressure shocks and average out pressure fluctuations.
    • Cooling elements prevent temperature spikes by protecting the pressure instrument from high or low process temperature. Air flow across heat exchanging fins reduces or increases the temperature of the system fill fluid to protect the pressure measuring instrument.
    • Overpressure protectors are designed to avert spikes and overpressure damage. These protectors provide protection for pressure gauges against the effect of pressures exceeding their maximum pressure rating.
    • Mini-siphons can stop corrosion by eliminating gauge whip and vibration as well as, protects the pressure gauge from harmful steam, hot vapors and liquids, and contains a unique inner chamber that reduces pressure surges and “water hammer”.
    • Diaphragm seals protect the gauge from slurry or viscous service and prevent corrosive and noxious process materials from reaching the gauge.

    Reasons Pressure Gauges Fail

    Author: Wika

    Preventing pressure gauge failure is of critical importance in the field. Many times there is no way of knowing why a gauge has failed. However, many times it is preventable. Here are seven reasons why pressure gauges may fail:

    1. Mechanical Vibration
    The oscillating, reciprocating or other periodic motion of a rigid or elastic body or medium forced from a position or state of equilibrium

    2. Pulsation
    Rhythmical throbbing or vibrating; a periodically recurring alternate increase and decrease of a quantity (i.e., pressure, volume or voltage)
