The flow meters of the DR08 series operate according to the turbine wheel principle.
The liquid flows into the turbine body and causes a rotor to rotate in proportion to the flow. Depending on the model, this rotation is converted into an output frequency by an inductive proximity sensor or a Hall sensor.
One of the main features of the DR08 turbine flowmeters is the very low series scatter of identical devices. This eliminates the need for individual adjustment of the individual turbines to the respective downstream electronics, making the DR08 ideally suited for use in series applications
