QL 326 Data Sheet

Flow Volume Sensor HySense® QL 326

The HySense QT 326 is a high precision turbine flow meter with a controllable load valve which measures volumetric flow rate in stationary and mobile hydraulic equipment. Testing of pumps, e.g., the recording of a characteristic curve in dependency of the pressure, is simplified significantly by using the HySense QL 326. A controllable proportional valve simulates a non-existent load. Flow and pressure are detected by a turbine volume flow meter and a pressure sensor. Additionally, a p/T-test point allows for connecting an optional temperature sensor.
