HFT 3100 with HART interface is a compact flow rate transmitter with flameproof enclosure specially developed for applications in hydraulic systems and other fluid power systems.

The triple approval in accordance with ATEX, IECEx and CSA enables universal, worldwide utilization of the devices in potentially explosive atmospheres.

The HFT 3100 operates in accordance with the turbine principle, which means that the rpm of an impeller wheel rotating in the flow of the media is measured and convertedmore
