OVERVIEW
Plug-in paddlewheel flow sensor
The paddlewheel technology is based on a contactless transfer of the rotary motion into a frequency signal. The flowing liquid sets the paddlewheel in motion. The permanent magnets used in the paddlewheel, which are not in contact with the medium, generate a frequency signal which is proportional to the flow velocity of the liquid. The conversion of the flow velocity into a flow signal is defined by the proportionality factor K.
The paddlewheel rate sensor is designed for continuous measurement of the flow of neutral and weakly aggressive liquids containing low levels of solids. Flow speeds of 0.3 to 10 m/s can be measured. The sensor provides a frequency pulse signal proportional to the flow speed. Standardized fittings ensure easy installation of the measuring transducer in tubes ranging from DN15 to DN400 (see Data Sheet 406090).
- Simple mounting.
- For pressures up to PN10 and temperatures up to +70°C.
- Three-wire frequency pulse signal is suitable for direct connection to PLC.
