  • WO2010 / 039045 Al discloses a water management system with a valve and a flow meter in the water line, which throttles the stepwise water supply when the water consumption exceeds a limit. In case of leakage, the valve is closed. When throttling the inflow of water, the hydraulics are changed. There is a risk of unwanted noise.

Since the server receives the data of a variety of leakage protection arrangements, these data can be evaluated, if necessary, with the consent of the resident and / or anonymously in their entirety and statistics are created. This opens up new possibilities of quality control for the manufacturer to the manufacturer or service provider.
  • the central server can be set up and managed by the manufacturer or an administrator.

  • the flowmeters are formed by a turbine, from whose rotational speed and number of revolutions the flow rate and the flow volume made can be calculated. But there are also other flow meters, such as ultrasonic knife for determining a flow rate conceivable.
  • the sole use of a pressure sensor is not suitable since it only measures the pressure, but not the flow rate, and requires a shut-off during the measurement.
  • At least one of the fitting parts additionally has an additional pressure sensor and / or temperature sensor.

For this purpose, in a period in which a water withdrawal at a tapping point is unlikely, such as late at night, shut off the water supply with the barrier. Before and after the shut-off period, the pressure is determined with the pressure sensor. In the case of a pressure drop, leakage is assumed.

  • one of the valve parts with control unit is centrally located in the water supply of the water installation and all other fittings parts with control unit are hydraulically installed behind it.
  • Each water flow is thus once registered and evaluated at the central control unit (master) and at the local control unit (slave).
  • the central control unit can determine whether a very large flow rate is due to the simultaneous withdrawal of water at several taps or to a loss of water in only one place.

  • a comparatively high maximum flow rate must be set. The resulting damage is then limited badly.
  • the use of multiple fittings allows one to set the maximum flow rates to smaller values towards the end because they monitor the flow of fewer parts of the fitting.
  • the front fitting part is set to a larger maximum flow, but can be controlled via the controller so that it checks first or check at the central server, whether the flow distributed to the underlying dashboard parts or whether this exclusively from that of this fitting part monitored area is coming. Only in the latter case, a barrier is required. As with the use of a branched arrangement, it is also easier to localize the cause of the leakage. In addition, the barrier can be targeted.
  • a control unit works both as a master and as a slave. The control unit usually belongs to the fitting closest to the water supply.
  • the data with the flow rates at each ECU can also be stored in a dynamic database in the central server. Then it can be determined whether a high total flow rate at the water inlet is due to conventional water extraction at several taps or to a pipe break. Accordingly, the tolerance of the fitting part at the water inlet can be set to a low value. For higher values, it is first checked where they come from before the shut-off for the entire building. Only if no correspondingly high total removal is registered at the slaves will be blocked.

  • the backflow preventers 332 and 334 open in the outlet direction. No water can flow from the installation behind it back into the supply line. If a component, such as the water meter or the pressure reducer to be replaced, the barrier is closed. This prevents water from flowing from the supply line into the valve.

Downstream of the barrier 418, a turbine-type flowmeter is disposed in the housing 412. A commercial, calibrated water meter 424 with a consumption indicator 426 is disposed downstream of the housing 412. Both the flow meter and the water meter 242 provide a flow representative signal to the controller 420. The controller may monitor leakage in this manner. In addition, the consumption detected by the calibrated water meter 424 may be communicated to a central server. It is no longer necessary to have the water meter read by a person.
