GPI Insertion Paddle Wheel Flowmeter

GPI Introduces New Insertion Paddle Wheel Flowmeter

This cost effective flowmeter is simple to install and handles a wide range of low viscosity liquids. Applications include irrigation, HVAC (Hot and Chilled water), water distribution, municipal and industrial water, and waste water. The stainless steel and PVDF construction makes it ideal for batching and blending many industrial chemicals. The Insertion Meter has a high pressure submersible design and electrical interference immunity. Pipe sizes are 1.5 inches to 36 inches (40-900 mm). European CE compliant.

How it works:
Flow passes through a pipe causing the durable PDVF rotor to spin. Magnets installed in the 316 stainless steel rotor pass by pulse sensors within the transducer body and in turn this produces frequency outputs proportional to flowrate.

A non magnetic rotor is available for liquids containing ferrous suspensions (metal fragments). Major obstructions such as pumps, valves, reducers, or strainers should be kept well outside the straight run pipe section (10 feet is recommended). An optional bi-directional discriminator output is available, as well as an intrinsically safe Reed switch for hazardous area operation.

Other features:
  • Compatible with various GPI Electronics
  • Dual independent pulse outputs
  • PVDF bearing
  • A precision ground stainless rotor shaft
  • Dual independent pulse outputs
  • Direct input to PLC and Computer
  • Integral or remote high speed preset batch controller

Tubing vs Pipe

Standard fluid line systems, whether for simple household use or for the more exacting requirements of industry, were for many years constructed from threaded pipe of assorted materials and were assembled with various standard pipe fitting shapes, unions and nipples. Such systems under high pressures were plagued with leakage problems besides being cumbersome, inefficient and costly to assemble and maintain. Therefore, the use of pipe in these systems has largely been replaced by tubing because of the many advantages it offers.

Old Method - Each connection is threaded – requires numerous fittings – system not flexible or easy to install and service connections not smooth inside – pockets obstruct flow.

Modern Method - Bendable tubing needs fewer fittings - no threading required - system light and compact - easy to install and service - no internal pockets or obstructions to free flow. (Use a Parker Tube Bender)

Major Advantages of Tubing vs. Pipe

  1. Bending Quality - Tubing has strong but relatively thin walls: is easy to bend. Tube fabrication is simple. (Parker Tube Bender)
  2. Greater Strength - Tubing is stronger. No weakened sections from reduction of wall thickness by threading.
  3. Less Turbulence - Smooth bends result in streamlined flow passage and less pressure drop.
  4. Econmy of Space and Weight - With its better bending qualities and a smaller outside diameter, tubing saves space and permits working in close quarters. Tube fittings are smaller and also weigh less.
  5. Flexibility - Tubing is less rigid, has less tendency to transmit vibration from one connection to another.
  6. Fewer Fittings - Tubing bends substitute for elbows. Fewer fittings mean fewer joints, fewer leak paths.
  7. Tighter Joints - Quality tube fittings, correctly assembled, give better assurance of leak-free systems.
  8. Better Appearance - Tubing permits smoother contours with fewer fittings for a professianal look to tubing systems.
  9. Cleaner Fabrication - No sealing compounds on tube fitting connections. Again no threading: minimum chance of scale, metal chips, foreign particles in system.
  10. Easier Assembly and Disassembly - Every tube fittings connection serves as a union. Tube fitting connections can be reassembled repeatedly with easy wrench action.
  11. Less Maintance - Advantages of tubing and tube fittings add up to dependable, trouble-free installations.
