Coolants are fluids with a high thermal capacity which flow around or through a device to keep that device from overheating by transferring heat to an area where it can dissipate. Coolants are common in automotive, HVAC, industrial processing, power generation, and other industrial and commercial applications. Measuring, monitoring, and controlling flows of coolants is an important consideration for those applications.

Ideally coolants are non-toxic, chemically inert, and neither causes nor promotes corrosion of the cooling system. In reality, though, coolants can coat internal parts or equipment and over time may contain particles. Equipment used to measure, monitor, and control flows of coolants should have few moving parts or pieces which intrude into the flow stream.
