The flow rate transmitters of the EVS 3100 series (aluminium series) are specially conceived for utilisation in hydraulic and other fluid technology plants. They operate in accordance with the turbine principle, which means that the rpm of an impeller wheel rotating in the flow of the media is recorded and converted into a 4 ... 20 mA analogue signal. Two additional G1/4 threaded bore holes in the turbine housing provide the flow rate transmitter with additional connection options, e.g. for temperature and pressure sensors. The flow rate transmitters of the EVS 3100-H series with HSI sensor detection were specially developed for use in conjunction with the HYDAC measurement devices HMG 500, HMG 510, HMG 3000 and CMU 1000. For data transmission purposes, the EVS 3100-H devices are equipped with an HSI interface (HYDAC Sensor Interface). Thanks to this, the HSI sensors are recognised completely automatically by the HYDAC measurement devices listed above and all necessary basic device settings are then immediately undertaken automatically.
