INS-FM18D Coolant Flow Meter v 1.0

Flow Rate Range:

2.0 - 15 LPM (0.53 - 4 GPM)

Fluid Temperature Range:

0 - 70 ºC (32 - 158 ºF)

The Koolance INS-FM18D flow meter uses a magentic reed contact switch which responds to internal

impeller rotation. It is powered by 12V DC. The integrated LED display reports flow rate in liters per minute

(LPM). Residual air in the liquid will reduce flow meter accuracy.

Be sure to install the flow meter in the correct liquid direction.

This is indicated by the arrow on the flow meter’s body. If the

opposite direction is desired, detach the flow meter from the

black bracket and reattach facing the opposite direction.
