Part Number : PFT-IAN-B111-S

Brass or 316 SS bodies are offered for the Model PFT-IAN-B111-S Insertion Paddlewheel Flowmeters, which are used to measure liquid flow rates in pipes ranging in size from 1-1/2 to 40". The device produces a 4–20 mA output or a frequency proportional pulsed output. The 4 to 20 mA variants feature a linear velocity output, with 4 mA equal to 0 ft/s and 20 mA equivalent to 25 ft/s. The pulse models provide a square wave output signal with frequency proportionate to the flow velocity.

Long product life because of the superior wear protection provided by the bearings and shaft, even in situations with particulates.
Use in submersible and weatherproof irrigation applications.
Using a single unit that can be adjusted over a wide variety of pipe sizes can save time and inventory.
Flexibility in application with an array of wetted material options.
With an integrated 4–20 mA output, there is less need for extra peripheral components.
Sensing technology eliminates issues about magnetic material in flow since it employs inductive sensing instead of magnets.
