Description:

The HEF is a Hall Effect sensor which is compatible with the Aluminum, 303 Stainless Steel and 316 Stainless

Steel body JV-CG and JV-KG series of flow meters. The sensor detects the rotation of the flow meter’s 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%.

HEF signal outputs are protected with a self-resetting fuse. This fuse has a 50mA nominal trip point. When a

trip occurs, turn off power to the sensor and remove output load to reset fuse.

The HEF sensor has two different output configurations: HEF-A or HEF-AA for a sinking output and HEF-B or

HEF-BB for sourcing output.

Installation:

• Ensure that the flowmeter sensor cavity is free of debris prior to installing pickup

• Make sure the sensor mounting screws line up with the mounting holes. If they do not, remove and rotate

the sensor 180°
