HFT 3100 with HART interface is a compact flow rate transmitter with intrinsically safe specially developed for applications in hydraulic systems and other fluid power systems. The double approval in accordance with ATEX and IECEx enables universal, almost world-wide utilization of the devices in potentially explosive atmospheres.

The current flow is determined by means of a sensor according to the turbine principle In addition with the analogue 4-20 mA output of the measured value, digital communication is possible by means of the HART protocol.

The main fields of application are in the oil & gas industry, gas turbines. The device is also used in mining applications as well as in areas with high dust loads.

Two Additional threaded bore holes in the turbine housing provide the flow rate transmitter with Additional connection options, e.g. for temperature and pressure sensors.
