AW-Lake CAPM-2 Carrier Frequency Sensor is a Carrier Frequency sensor, which means there is no permanent magnet in the pickup, and any magnetic drag on the flow meter is avoided. The CAPM-2 requires a supply voltage between 10 VDC and 30 VDC.

A diode in the supply input prevents damage to the module in case the polarity of the supply voltage is wrong. The output signal is a square wave, voltage pulse of approximate amplitude (supply – 1.5 V). The frequency is proportional to the flow rate. For use with JV-CG and JV-KG meters (not for use with aluminum meters).
AW-Lake CAPM-2 Carrier Frequency Sensor Features:
- Meter Compatibility: Used with JV-CG and JV-KG meters (not for use with aluminum meters)
- Output Signal: Square wave, voltage pulse of approximate aplitude (supply - 1.5V)
- Sourcing Output: PNP type sourcing open collector transistor
- Intrinsically Safe: Intrinsically safe CAPM-2o version available
- IS Safe Version: UL & cUL certified for use in Class 1, Div 1 locations
Installation:
- Ensure that the flow meter sensor cavity is free of debris prior to installation.
- Screw the CAPM-2 into the flow meter by hand until the sensor nose contacts the bottom of the cavity.
- Do not screw in harder than hand tight, as a thin metal section is under the sensor nose
