Abstract

The invention relates to a device for detecting a water leak in a network, including a water meter, a pulse emitter adapted for transmitting information from the meter to a data processor. The data processor includes at least two pulse meters adapted for operation according to a given flow value of the network and a device for measuring network flow capable of selecting the meter adapted to the measured flow.

Claims

1. Device for detecting a water leak in a network, comprising a water meter, a pulse emitter transmitting information read from said water meter to data-processing means, wherein said data-processing means comprises at least two pulse meters operating according to a given network flow-rate value and means for measuring said network flow-rate permitting to select the meter adapted to the measured flow rate.

2. Device according to claim 1, wherein the means for measuring the network flow-rate comprises a time meter measuring the time of a pulse of a consumed quantity, and wherein said data-processing means further comprises means for selecting the meter depending on this measured time and then comparing said measured time with a value in memory, the value being a time value of a preceding pulse increased with a delta.

3. Device according to claim 1, wherein the data-processing means comprise a programmable automate having at least seven pulse meters, each meter being associated to a given network flow-rate value.

4. Device according to claim 1, wherein the measuring means for measuring the network flow-rate are comprised of a water meter provided with a flow-meter the needle of which is provided with a target and to which is connected, through adapted means, a pulse emitter.

5. Device according to claim 1, further comprising:

a connection adapted for fixing the pulse emitter to the water meter.

6. Device according to claim 1, wherein the data-processing means for processing the data can preferably be formed of a programmable automate.

7. Device according to claim 1, wherein the processing means of a set of electronic cards with a locked program performing the same operations as said programmable automate.

8. Device according to claim 7, wherein said at least one combination of a meter and an emitter in each area of the network are monitored.

9. Device according to claim 8, wherein a differential existing between at least two successive combinations is calculated by establishing the flow-rate difference between these two combinations, in order to obtain a value that, when not equal to zero, shows a leak on the network.

10. Method for implementing the device for detecting a water leak according to claim 1, the method comprising the steps of:

measuring a time of a pulse corresponding to a consumed quantity;

selecting a meter corresponding to a value of said time;

comparing said value with a time value stored in a memory;

determining either said value is lower than or equal to said time value in memory, wherein a corresponding meter is incremented with the consumed quantity and said value is saved in the memory; and

determining said value is higher than said time value in memory, said value being saved in the memory serving for calculating a reference value for a next measurement of pulse time.

11. Method according to claim 10, wherein the time value in memory corresponds to a time value of a preceding pulse increased with a predefined delta.
