Koolance INS-FM19 Coolant Flow Meter

Koolance's inline flow meter provides a visual and 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.

Flow rate range = 1.0-15 LPM (15.6-240 GPH). Fluid temperature range = 0 - 70°C (32-158°F). Maximum pressure = 2kgf/cm2 (28.5 psi) @ 25ºC. Wire length is about 28 (70cm), with product dimensions of approximately 1 x 1.9 x 0.75 (2.5cm x 4.8cm x 1.9cm). Materials are nickel-plated brass and acrylic with an external aluminum shell.
