Description:
The IR-P is an infrared optical sensor which is compatible with the AW Flow Meters JVK series Positive
Displacement plastic gear flow meters. The sensor 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%.
IR-P 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 IR-P sensor’s output configuration is: IR-PA for a sinking output, IR-PB for a sourcing output.
Installation:
• Ensure that the flowmeter sensor cavity is free of debris prior to installing pickup
• A mounting bracket is required for sensor mounting
• 4 Steps to properly install sensor:
1- Securely fasten mounting bracket on flow meter
2- Turn set screws counter clockwise until they are not visible inside the mounting bracket
3- Install sensor into mounting bracket 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
