| PS600 Series Pulse Output Flow Sensor
» For new designs, please see the 6000 Series Flow Meter
• Flow rates from 0.1 – 60 GPM
• 5–24 VDC pulsed output
• Pressures to 250 PSI
• Economical for cooling flow and process control
• Visual flow indication
Proteus PS600 series sensors use a turbine principle to generate a pulsed voltage that varies with flow. Magnets in alternate spokes of a rotor induce a voltage in a Hall-Effect sensor when flow turns the rotor. The variable frequency output from this simple and reliable sensor may be read by your electronics to determine flow rate.
The output voltage is a square wave, which varies from 5 to 24 VDC, depending on the voltage supplied by the user. The output frequency range varies somewhat from model to model, but generally ranges from about 5 Hz at the bottom of the flow range for any model to 120 Hz at maximum flow.
Calibration The calibration curve varies from unit to unit. Individual calibration curves may be supplied on request for a modest additional charge.
