Koolance's inline flow meter provides a visual and electronic indicator of real-time coolant flow rate. Compatible with 1/4" (6mm), 3/8" (10mm), or 1/2" (13mm) ID G 1/4 BSP threaded nozzles.

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 = 6kgf/cm2 (85 psi). Wire length including the frequency multiplier board is about 26" (66cm), 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.
