Hall Effect Liquid Water Flow Sensor Switch

G3/4 Hall Effect Liquid Water Flow Sensor Switch
E-WFS-GE
  • E-WFS-GE G3/4 Hall Effect Liquid Water Flow Sensor Switch
  • E-WFS-GE G3/4 Hall Effect Liquid Water Flow Sensor Switch
  • E-WFS-GD44 G1/2 Hall Effect Liquid Water Flow Sensor Switch
  • Use to monitor water usage and to detect leaks/stoppages.
  • Pulse frequency output is linearly related to flow rate.
    • Note: This is not a precision sensor – the pulse rate varies some depending on the flow rate, fluid pressure, and sensor orientation.
  • Rugged brass construction.
  • Sensor Type: Hall effect
  • Working Voltage: 4.5 to 18V DC
  • Max Current Draw: 10mA at 5VDC
  • Available with G1/2 or G3/4 external thread diameter.
    • E-WFS-GD44
      • Working Flow Rate: 1 to 30 L/min
        • When used with E-xD, the flow rate is 1 to 26.18 L/min
      • Flow Rate Pulse Characteristics: Frequency (Hz) = 11 x Flow Rate (L/min) - 3
      • Accuracy: ±10%
