Ask an experienced consultant:
The HM HP (HP for high pressure connection) turbine flow meter series is used to measure continuous and discontinuous flow rates with very high operating pressures. They are mainly used for lubrication and non-lubrication media. They are particularly suitable for low and medium viscosity liquids, such as water, emulsions, additives and inhibitors.
Only high-grade steels that even withstand corrosive liquids are used in the production of turbine flow meters. The extreme pressure resistance of the flowmeter can be guaranteed through the use of a high-strength housing material. Combined with the use of tungsten carbide bearings, the HM HP guarantees optimum measurement accuracy and an extremely long service life even under the toughest application conditions.
