Turbine Flow Meters (HM)

for lubricating and non-lubricating media

The HM F turbine flow meter series (F for flange connections) is used to measure continuous and discontinuous flow rates. They are mainly used for lubrication and non-lubrication media. They are particularly suitable for low and medium viscosity liquids, such as water, emulsions, glycol mixtures and light oils.

Only high-grade steels that even withstand corrosive liquids are used in the production of turbine flow meters. There are no welding seams in contact with the media thanks to the innovative design. Combined with the use of tungsten carbide bearings, the HM F guarantees optimum measurement accuracy and an extremely long service life even under the toughest application conditions.
