Abstract (en)

[origin: EP0821164A2] The switching method provides switching signals for the electric pump (1) in response to flow variations in a bypass line (5) for the main flow pipe, detected via a measuring device (11). The latter may provide the flow direction and flow quantity, which are evaluated for providing the pump switching signals, with a pressure switch (12) detecting leakages below the response level of the measuring device, for switching in the pump.
