In any production control system it is vital to know the fluid quantity involved in the process.
Burkert Flow sensor, This flow meter/transmitter/threshold detector with display is designed for use in clear, neutral or aggressive liquids.
A flow sensor will need to accurately indicate the flow.
Burkert Flow sensor – Paddle wheels need direct fluid contact, also, best with low solid content with similar characteristics to water.
The paddle wheel has permanent magnets, and rotates by fluid flow, also detected by a Hall sensor outside the fluid area.
Converted to a square wave frequency signal by the Integrated electronics, also used by the process controller.
One gear has a permanent magnet also the rotary motion, detected by the Hall sensor.
Paddle wheel construction and bearings also the sealing materials should be considered against fluid characteristics.
The voltage, directly proportional to flow rates and also provide very accurate flow data.
Changes in flow velocity affect the time for each signal traveling between sensors.
This signal, converted to analogue and utilised by the process control software.
Flow direction is key with this type of sensor also is best where flow is unidirectional.
