PFA (0045, 0085, 00125) Teflon Turbine Flow Sensor
PFA wetted parts, F.S. ranges of 2, 20, & 40 lpm, Frequency/Analog OutputDESCRIPTION
The PFA flow sensor has low flow sensing capabilities in a wide range of applications, and is suitable for clear, opaque, neutral, corrosive and aggressive liquids including fuel.
An ultra-lightweight turbine follows the fluctuation of flow very accurately and generates a high resolution IR reflected digital output signal.
In either flow controlled or monitoring applications, the PFA flow sensor can measure flow rates and totalize. Optional elements built into the circuit include a programmable K factor, flow switch and a programmable batch feedback function for pump control.
External optional electronic packages include model 6100 digital to analog (4-20 mA) converter. Also model S601, a professional, solid batch and flow controller that can be used as a monitor and/or totalizer and model 6300 switch module for use with optional built-in flow switch and batch functions.
Features
- Turbine flow sensor with high resolution output

Working Principal:
A static worm forces the passing fluid to spin. The spinning fluid drives a rotor with reflectors into a frictionless rotation. A high resolution
infrared sensor determines the rate of flow by counting the passing reflections. The set up even allows the flow of opaque liquids to be
determined accurately. The ultra low mass of the rotor guarantees a quick response to changes in the rate of flow.
