Method for rating the hazard potential of a microbial contamination with a flow meter

摘要

The method involves storing a physical parameter e.g. volume, detected by a flow meter (1) and/or a parameter derived from the physical parameter in a register (6) of a memory device (5) of the flow meter when water temperature determined by a temperature sensor (10) exceeds a temperature threshold value. A measure for water quality i.e. contamination hazard, is determined and evaluated from the parameter stored in the register. An alarm signal is outputted when the measure of the water quality exceeds an alarm threshold value. An independent claim is also included for a flow meter comprising a computer device for executing a drinking water quality monitoring method.
