Series PFT Paddlewheel Flow Sensor
Brand: Dwyer Instruments, LLCThe 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- 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 to 20 mA Output with No Need for Additional External Components
- Sensor Technology Uses Inductive Sensing to Sense the Blades of the Impeller Therefor Does not Use Magnets Allowing low Flow Rate Monitoring with No Concerns Regarding Magnetic Material in The Flow
