The plastic paddle wheel flow meter of the DR56 series measure the flow of water and water-like (low viscous) media. They consist of a sensor and an optional transmitter.
The sensor has a paddle wheel which is mounted in a housing made of POM or ECTFE and is rotated by the flowing medium. This rotary motion is picked up by a Hall sensor system and emitted as a flow-proportional frequency signal. A convenient control unit with display is available as an option, which can also be mounted on the flow meter.
Typical applications
The DR54 impeller flow meters are very resistant to many process media due to their design made of insensitive plastics. Almost all low-viscosity liquids can be measured reliably and cost-effectively with this device.
