METHOD AND MEASUREMENT PROBE FOR THE PERFORMANCE OF MEASUREMENTS IN WATER SUPPLY SYSTEMS
First Claim
1. A method to detect water losses and to locate leaks in a water supply system (13), comprising the steps of locating measurement probes (1) at predetermined measurement points (11) in said system, the measurement probes including measuring elements for outputting measured quantities indicative of a flow rate, a pressure and noise integrated into each measurement probe (1), deriving from said probes (1) at intervals or continually measurements of flow data including flow rate and direction, water pressure and noise, analyzing said flow rate and direction, water pressure and noise data using an evaluation unit to determine a presence of and a proximity of a leak, and simultaneously connecting said probes to a noise correlator to determine a location of a leak between two neighboring probes, wherein in the manner of a random-check generator, different areas of said water supply system (13) are analyzed for water loss and leaks alternately and at repeated intervals.

Abstract
Measuring elements for the output of measured quantities in respect of the flow, namely the flow quantity and direction, the water pressure and the flow noise are integrated in a measurement probe (1) for water supply networks (13), whereby all these measuring elements are connected or can be connected to a data collector (12) by means of transmission by radio, modem or cable connection. The measurement probes are installed permanently at the key points (10) and at the most varied measurement points (11) following one another as closely as possible in the water supply network (13) and can thus contribute, by delivering all the necessary data, to the rapid tracing of leaks with pinpoint accuracy as well as to constant monitoring.
