Description:

The MAG is a Hall Effect sensor which is compatible with all AW Company and KEM Positive Displacement

gear flow meters except ZHM-04 to the ZHM-07KL and all AW Company and KEM turbine 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%.

MAG 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 MAG sensor has two different output configurations: MAG-PA for a sinking output and MAG-PB for a

sourcing output.

Installation:

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

• Swivel fitting is required for sensor mounting. Note: In order to recieve correct swivel fitting with your

sensor - you must specify meter part number when ordering

• 4 Steps to properly install sensor:

1- Securely fasten swivel fitting on flow meter

2- Turn set screws counter clockwise until they are not visible inside the swivel fitting

3- Install sensor into swivel fitting until sensor bottoms out in the sensor hole

4- Tighten set screws by turning clockwise

NOTE: DO NOT OVER TIGHTEN SET SCREWS OR SENSOR DAMAGE WILL OCCUR!

NOTE: WIRING SHOULD BE INSTALLED BY A QUALIFIED INSTRUMENTATION TECHNICIAN
