Indicators feature clear windows to visualize and indicate positive flow. Indicators do not feature an output. Choose an indicator with high-visibility orange rotor for darker fluids.
Sensors/Switches feature a Hall-effect sensor that produces a 4.5 to 24 VDC pulse output. Maximum current source output is 70 mA, and frequency output range is approximately 25 Hz at low flow to 225 Hz at high flow.
