Turbine Flow Meters for flow measurement of fuels, marine engine fuel monitoring, light fuel oil, thermal oil, solvents, tap and demineralised water as well as special models for refrigerants, pharmaceutical fluids, cryogenic fluids, liquefied gases and high-pressure applications.

Turbine flow meters are mediate volume transmitters similar to a Woltmann’s sailwheel meter. Thanks to extremely rapid response times and high resolution turbine flow meters are perfectly suitable for fast filling systems.

Due to an enormous pressure and temperature resistance turbine flow meters will also be the perfect choice for water torch systems, temperature control units, cooling circuits or painting systems, where the consumption of solvents and di-water needs to be measured.

Turbine flowmeters use the mechanical energy of the fluid to rotate a rotor in the flow stream. The turbine flow meter blades on the rotor are machined and positioned in such a way that energy from the flow stream is transferred into rotational energy. When the fluid moves faster, the rotor spins proportionally faster. KEM manufacturers its high precision rotors out of a single piece.

Shaft rotation can be sensed mechanically or by detecting the movement of the blades. Blade movement is often detected magnetically using a pick up with each blade or embedded piece of metal generating a pulse. When the fluid velocity increased, pulses increase similarly. The transmitter processes the pulse signal to determine the flow of the fluid.
