Turbine Flow Meters with Pelton Wheel (HM P)

for monitoring heating and cooling circuits

The HM P (P for Pelton wheel) series turbine flowmeter works according to the Pelton wheel turbine principle and is used to measure continuous and discontinuous volume flows. It is used primarily for cost-effective flow rate measurement in heating and cooling circuits. Even heavily contaminated media at very high temperatures can be measured thanks to the special design and bearing concept. Only high-grade steels that even withstand corrosive liquids are used in the production of the turbine flowmeter. Combined with the use of highly wear-resistant ceramic bearings, the HM P guarantees optimum measurement accuracy and an extremely long service life even under the toughest application conditions.
