Turbine Flow Meter PFAD Flow Sensor, Disposable

PFA Wetted Parts, F.S. Ranges of 2 & 20 lpm, Frequency Output


The PFAD disposable flow meter / flow sensor has been developed to perform a fast exchange of the flow tube to accommodate hygienic applications in the pharmaceutical industry. It is suitable for clear, opaque, neutral, corrosive and aggressive liquids including fuel.

A field replaceable ultra-lightweight turbine assembly follows the fluctuation of flow very accurately and generates a high resolution IR reflected digital output signal.

In either flow controlled or flow monitoring applications, the PFAD 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 flow monitor and/or flow totalizer and model 6300 flow switch module for use with optional built-in flow switch and batch functions.

 Turbine Flow Meter PFAD Flow Sensor, Disposable Working Principle

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.
