The DW-F flowtransmitter is a supplement to the DW-D deflector flowtransmitter and is fitted with a wheel sensor. The DW-F device type corresponds exactly to the structure of the DW-D device type with the exception of the sensor system. The DW-F works with a wheel instead of a paddle. This opens up additional possibilities of ideally adapting the HSW DW-F flow transmitter to the corresponding application areas.
