PFT-IAN-B111-S

The Series PFT Paddlewheel Flow Sensor is used to monitor liquid ow rates in pipes from 1-1/2 to 40˝ (40-1016 mm). The unit has one size-adjustable sensor and is available in brass or 316 SS body. The unit outputs a frequency proportional pulsed or 4-20 mA output. The pulse models are a square wave output signal with frequency proportional to the ow velocity and the 4-20 mA models have a linear output of the velocity with 4 mA equal to 0 ft/s and 20 mA equal to 25 ft/s.

FEATURES/BENEFITS

• Bearings and shaft offer excellent wear protection even in applications with particulate for long life

• Weatherproof and submersible rated for irrigation applications

• One unit adjustable over a large pipe size range

• Multiple wetted material choices offer application versatility

• Integral 4-20 mA output with no need for additional external components

• Sensor technology uses inductive sensing to sense the blades of the impeller therefore does not use magnets allowing low ow rate monitoring with no concerns regarding magnetic material in the ow

APPLICATIONS

• Irrigation

• Ground water remediation

• Cooling systems

• Pump protection

• Leak detection

• Filtration systems
