Series PDM Flowmeter Principle of Operation The Series PDM Flowmeter uses the oscillating piston principle where the passage of liquid causes a piston to oscillate smoothly in a circular motion within the measuring chamber. Each piston cycle passes a known volume of liquid from the inlet to the outlet port, magnets in the piston activate the reed switch and the solid state sensor to provide pulse outputs for remote flow, measurement and process control.

Series PDM Flowmeter Principle of Operation The diagram below shows the transition of fluid from the Inlet Port through the measuring chamber and then out the Outlet Port.

Series PDM Flowmeter: 

Series PDM Flowmeter Features 316L Stainless steel, Aluminium or UPVC construction Accuracy ±0.5% rate Has no stagnate chambers Measures High and Low viscosity liquids to 1,000,000cp No requirement for flow conditioning High Pressure models to 350 Bar Insensitive to mounting orientation

Series PDM Flowmeter: 

Series PDM Flowmeter Benefits Up to 70% cost saving for an installation requiring a stainless steel flowmeter Has only one moving part giving extended trouble free working life Installation flexibility in vertical or horizontal pipes, no need for straight pipe runs or conditioned flow

Series PDM Flowmeter: 

Series PDM Flowmeter Benefits No modifications are needed when measuring high viscosity liquids Can be cleaned in place using chemicals or controlled steam pressure/temperature Extremely compact and comparatively light weight Limited spare parts needed to support the product

Series PDM Flowmeter: 

Series PDM Flowmeter Outputs Reed Switch Output - Provides a voltage free contact closure. The reed switch is classed as a "simple device" and can be used in hazardous areas when connected via an approved intrinsically safe barrier. Square Wave Output - An open collector pulse output produced by a solid state Hall effect device. This 3-wire device requires 5-24 vdc excitation voltage and produces a high resolution square wave output.
