AW-Lake Quad-4 Hall Effect Sensor

AW-Lake Quad-4 Hall Effect Sensor is a microprocessor-based sensor for use with the JV-80/-90KL series of positive displacement flow meters. The Quad-4 sensor can detect both uni- and bi-directional flow. The sensors’ mode of operation is determined by an output selection switch located inside the housing. The Quad-4 detects the rotation of the flow meter gears and emits a frequency signal proportional to flow.

The output signal is a square wave pulse which has a duty cycle of approximately 50%. Quad-4 signal outputs are protected with a self-resetting fuse. This fuse has a 50mA nominal trip point. When a trip occurs, turn off the power to the sensor and remove the output load to reset the fuse. The sensor has two different output configurations: sinking output when jumpers JP1 & JP2 are removed and sourcing when jumpers JP1 & JP2 are shorting pins. The Quad-4 sensor circuit board is equipped with a red and green LED.

The red LED is a status LED which, when the sensor is operating properly, will flash once every 4 seconds, a fast flash will indicate a failure of one or more of the pick-ups. The green LED indicates the pulse of the input signal. Note that signals above 20Hz will look as solid green.
