Aluminum Turbine Flow Meters (HM U)

with ball bearings for hydraulic applications

The HM U turbine flow meter series (U for aluminum housing and ball bearing) is used to measure continuous and discontinuous flow rates. They are mainly used for lubrication media. Especially well-suited for oils and hydraulic fluids. Only materials of the highest quality and precision ball bearings are used for manufacturing the turbine flowmeter. The turbine housing supports the adaptation of pressure and temperature sensors to record all important parameters in hydraulic flows simultaneously. This makes the HM U the ideal measuring device for the evaluation of hydraulic systems.
