Abstract: A method for monitoring quality of a water flow in a pipe, by diverting a flow into a laser particle counter to count particles within a particle size interval in the water, to continuously determine the number of particles within the size interval, comparing the count with a reference value and taking a sample of the water from the pipe when the count exceeds a threshold value, and also diverting a flow of water from the pipe into a unit that separates the flow into fractions, and taking a sample of at least one of said fractions when the count exceeds a threshold value, and also sending an alarm signal when the count exceeds a threshold value. When the count exceeds at threshold value, the water is treated with ozone.

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.

Abstract: The method is for monitoring water quality in a water system. A pipe is provided for conveying water therein to a water system having a first particle sensor in operative engagement with the pipe. A second particle sensor of a monitor device is provided in operative engagement with the pipe upstream and outside the water system. The second particle sensor senses particles in the water of the pipe. The second particle sensor triggers a shut off of a valve, disposed downstream of the second particle sensor and upstream of the first particle sensor only when a sensed value of particles in the water reaches a predetermined level to prevent the water from entering the water system. The water in the pipe is diverted into a re-circulation line.
