The surveillance system consists of two flow meters based on the ultrasonic principle, placed in the inlet and outlet pipes respectively, and of temperature sensors in both pipes. MULTICAL® 801 monitors the mass difference that may appear between inlet and outlet pipes.Tap water systems The pulse signal from a tap water meter can be connected to MULTICAL® 801. In this way it is possible to monitor the tap water consumption. A running toilet cistern, leaky heating coils in the water tanks or other leaks can be monitored. If pulses from the tap water meter are received continuously for 24 hours, this indicates leakage.
