Abstract

The set period for flow monitoring is set back to zero each time the flow is below a predetermined value. A water meter (12) is used with a transmitter (13) which transmits pulses dependent upon the extent of the flow. A comparator (17) compares the number of pulses during a predetermined time interval with a set number of pulses, providing a signal where the set number of pulses is not achieved. A relay (19) with retarded switch-on after a predetermed period is coupled to the comparator so that it is set back to zero by the signal. An indicator (21) indicates the undesired leakage when the retardation relay is switch on. A further indicator is connected to the comparator to show the absence of undesired leakage dependent upon the signal, and a device is available to set it back to the starting point.
