Koolance INS-FM19-PA User Manual

1
Koolance flow meters use a normally­open magentic reed contact switch which responds to internal impeller rotation.
The flow meters should not be directly connected to high power outputs like 12VDC fan headers or similar controllers. If connected directly to a custom circuit, the intended current range is 50-100mA. A signal graph is provided to the right:
Specifications
Flow Rate Range:
1.0 - 15 LPM (0.26 - 4 GPM) Fluid Temperature Range: 0 - 70 ºC (32 - 158 ºF)
IMPORTANT NOTES: Be sure to install the flow meter in the correct liquid direction! This is indicated by the arrow on the flow meter’s body. Residual air pockets in the flow meter will not result in an accurate reading.

With ADT-FM03, flow meter “RPMs” represent approximate coolant flow rate in mL/min, and not actual revolutions. Be aware that 3rd-party software and BIOS programs must be configured properly if the flow meter will be used to initiate a safety procedure.
The connections and functions for ADT-FM03 are illustrated below.
