A METHOD INVOLVING MEASURING OF WATER QUALITY AND/OR DETECTION OF ONE OR MORE SUBSTANCES IN A WATER FLOW

摘要

The present invention describes a method involving measuring of water quality and/or detection of one or more substances in a water flow, said method involving the steps of using a sensor system comprising at least two electrodes, for sending frequency from at least one electrode and receiving a response from at least another electrode, wherein the method involves filtration over one or more frequency ranges in the response, to measure the impedance and using the impedance as an indicator of the water quality and/or for detection of one or more substances in the water flow.
