Höntzsch vane wheel anemometers are now connectable to ALMEMO evaluation units via the optionally available D6 plug. Even instruments sensing the +/- direction of flow as well as vane wheel flow sensors for high working temperatures or special materials are now available! The characteristic linearization of the sensor is stored in the D6 connector. The storing of the sensor linearization of characteristics is done in the D6 plug. Measurement uncertainties are always < 1% of measured value + 0.5 % FS.
