HM P

Turbine Flow Meters with Pelton Wheel 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.
