BSPP Fittings

Koolance's inline flow meters provide electronic indication of real-time coolant flow rate. G 1/4 BSPP fitting threads, and primary materials are stainless steel and nickel-plated brass. Approximate read range is 2.0-20 LPM (32-317 GPH). Wire length is about 28" (70cm).

Koolance DCB-FM01 or CTR-KSM100 can be used to display the flow rate, if not connected to a compatible Koolance cooling system.

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.
