摘要： In order to control the tightness of a central heating system (10, 11), the system is provided with a flow meter (8, 9) and a valve (6, 7) in the flow (3) and return pipes (4), respectively. Hereby it becomes possible to monitor the liquid flow through the flow meters (8, 9) and in a control unit (15) to compare the signals from the flow meters (8, 9). When a certain limit value is exceeded, an electric motor on the inflow flow (6) is ordered to shut off the flow of water into the system (10, 11) and a signalling device (16), if any is activated. In order to be able to control the water flow and the tightness of a water system (Fig. 3), the branch pipe (3) is connected to a motor valve (6) and a flow meter (8), before the water is led the water pipe (10) of the building. The flow meter (8) gives electrical signals to an electronic control unit (15, 18) which compares the electric signals being proportional to the water flow with the pre-determined limits, and when the flow is in excess of the upper limit and/or below the lower limit, a signal is immediately given to the motor valve (6), which will shut off the water flow in the system.
