Abstract

The method is for monitoring water quality in a water system. A water pipe is provided for conveying water therein. A particle sensor is in operative engagement with the water pipe. The particle sensor continuously counts particles in the water of the water pipe. The particle sensor triggers the taking of a water sample only when the particle count reaches a predetermined level.

Claims

1. A method for monitoring water quality in a water system, comprising:

providing a pipe for conveying water therein, a particle sensor in operative engagement with the pipe;

the particle sensor continuously sensing particles in the water of the pipe; and

the particle sensor triggering a taking of a sample only when a sensed value reaches a predetermined level.

2. The method according to claim 1 wherein the method further comprises the particle sensor counting particles in the water.

3. The method according to claim 1 wherein the method further comprises diverting water to a flow regulator and then to the particle sensor to counting particles.

4. The method according to claim 1 wherein the method further comprises the particle sensor automatically taking the water sample when the particle count reaches the predetermined level and storing the water sample in a refrigerator.

5. The method according to claim 1 wherein the method further comprises the particle sensor triggering a processor to open and close valves.

6. The method according to claim 5 wherein the method further comprises the processor sending an alert signal to an operator only when the particle count has reached the predetermined level.

7. The method according to claim 1 wherein the method further comprises diverting water in a pipe directly from the water pipe into the refrigerator without passing through the particle sensor.

8. The method according to claim 1 wherein the method further comprises diverting water in a downstream pipe directly into the refrigerator without passing through the flow regulator.

9. The method according to claim 1 wherein the method further comprises the operator sending a crisis signal to a crisis contact.

10. The method according to claim 1 wherein the method further comprises the particle sensor taking the water sample when a particle count has reached a peak value.
