PVDF Disposable Turbine Flow Sensor

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

DESCRIPTION

The PVDF Turbine Flow Sensor has been developed to perform a fast interchange of the flow tube to accommodate hygienic applications in the medical, pharmaceutical, and bio-technological industries. It has low flow capabilities and high resolution square wave output. The flow tube can be sterilized to 140°C (284°F) and is gamma radiation resistant up to 50 kGy. These features make this model ideal for monitoring and controlling fluid flows in hygienic applications.

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

In either flow controlled or monitoring applications, the flow sensor can be used to measure and totalize flow rates. Optional elements built into the circuit include a flow switch and a programmable batch feedback function for pump control.

FEATURES

• Turbine flow sensor with high resolution output
• Flow measuring by revolutionary IR turbine reflection
• PVDF for high chemical and corrosion resistance
• High accuracy and repeatability
• Meets all the requirement of the US Pharmacopeia Class VI
• BSE/TSE certificate available
• All wetted parts are made of PVDF with ruby bearing
• Low voltage (5v) option available (LV Series)
• PVDF flow tube gamma radiation resistant up to 50kGy
• Suitable for opaque liquids

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.
