Koolance's inline flow meter can provide an electronic indicator of real-time coolant flow rate. Uses G 1/4 BSPP threads. INS-FM19 is electronically identical to INS-FM17N, but has an external metal shell for greater durability.

A frequency circuit (sold separately) multiplies the RPM signal to allow it to be read by most fan tachometer headers (such as those found on ATX motherboards). This signal 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.

Wire length is about 28" (70cm). Primary materials are nickel-plated brass and acrylic with an external aluminum shell.

Liquid Coolants

Koolance's product warranty does not cover the use of 3rd-party coolants, coolant additives, or corrosion. Koolance LIQ-702 or LIQ-705 coolants are strongly recommended to help avoid issues with mixed metals or biological growth. Additionally, do not use aluminum with bare (unplated) copper or bare (unplated) brass in the same system. Do not use silver with nickel in the same system.
