Description

The Series PFT Insertion Paddlewheel Flowmeters are used to monitor liquid flow rates in pipes from 1-1/2 to 40" and is available in brass or 316 SS body. The unit outputs a frequency proportional pulsed or 4 to 20 mA output. The pulse models are a square wave output signal with frequency proportional to the flow velocity and the 4 to 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 Long product life even in applications with particulate due to bearings and shaft that offer excellent wear protection Use in irrigation applications with weatherproof and submersible ratings Save time and inventory with one unit that is adjustable over a large pipe size range Application versatility with a variety of wetted material selections Reduce need for additional external components with integral 4-20 mA output Eliminate concerns regarding magnetic material in flow due to sensor technology, which uses inductive sensing and no magnets SPECIFICATIONS Service: Water-based fluids. Range: 1.2 to 25 ft/s (0.37 to 7.62 m/s). Wetted Materials: Body and fitting: Brass or 316 SS; Fitting O-ring: FKM standard, silicone or Buna-N optional; Impeller: 316 SS; Shaft: tungsten carbide standard or 316 SS optional; Bearing: PTFE standard. Linearity: ±1.0% of FS. Repeatability: ±0.5% of FS. Temperature Limits: -40 to 212°F (-40 to 100°C). Pressure Limits: 400 psig (27.6 bar) @ 100°F (37.8°C), 325 psig (22.4 bar) @ 212°F (100°C). Process Connection: 1-1/2" NPT male standard, 2" NPT male optional. Output: > Pulse: NPN open collector with square wave output, rated 60 V @ 50 mA maximum. Frequency: 3.2 to 200 Hz. Pulse Width: 2.5 msec
