Abstract
The invention is in a method of analyzing the water of an industrial water system wherein an analytical device is used to measure some parameter capable of being measured in the water of said industrial water system, the improvement involving using a water movement device that is capable of moving a sample of water into the sample chamber of said analytical device and is also capable of moving the same sample of water back out of said analytical device in a manner such that the filters present in the piping of said industrial water system are back flushed out every time the water movement device moves a sample of water in and out of said analytical device. Optionally an air sparge is used to enhance the cleaning of the filters.
