Koolance Flow Meter Frequency Adapter ADT-FM002K

The Koolance ADT-FM002K allows a Molex 4-pin 12V PSU connection to power or disable LED lighting of Koolance INS-FM15 and INS-FM16 Flow Meters. It also multiplies the flow meter RPM signal to allow it to be read by most fan tachometer headers (such as those found on ATX motherboards).

The flow meter RPM reading is intended to allow fan detection software (including BIOS) to enable the appropriate alarm or shutdown procedure if the flow meter impeller stops rotating. The "RPMs" represent approximate flow meter coolant in mL/min, and not revolutions.

CAUTION: Make sure to properly insulate the circuit from chassis ground, or permanent damage can occur to the circuit and/or flow meter. An insulating pad is included.
