Leak detecting and quantifying method for water line, involves continuously measuring conductivity of water in downstream of each point, and calculating rates of water flowing in upstream and downstream of break-point, from measurement

摘要

The method involves instantaneously injecting a water conductivity modifying tracer e.g. sodium hypochlorite, into points (I1, I2) respectively in upstream and downstream of a supposed break-point (F) in a water line (1). Conductivity of water is continuously measured in downstream of each of the points from an injection time till a time at which the conductivity returns to a value before injection of the tracer. Rates of water flowing in upstream and downstream of the break-point are calculated from the measurement by placing water conductivity measuring devices (2-5) each with electrodes. An independent claim is also included for a device for measuring conductivity of water for implementing a leak detecting and quantifying method.
