Abstract
A flow meter includes a flow sensor for conducting fluid in a measuring direction and an opposite measuring direction, alternatively. Evaluation electronics coupled to the flow sensor generate a sensor signal corresponding to the flow rate of the fluid. A first subcircuit converts the sensor signal to a flow rate signal and a second subcircuit coupled to the first subcircuit generates an output signal representing the flow rate in the measuring direction. A third subcircuit fed by the flow rate signal delivers a control signal for controlling the generation of the output signal. The third subcircuit determines a flow when the fluid flows in the measuring direction and a counterflow when the fluid flows in the opposite direction, and calculates a balanced flow therefrom. Depending on the balanced flow, the third subcircuit controls the second subcircuit with the control signal to generate the output signal in a predetermined manner.
