2- and 3-Elektode systems. A nozzle of the flow-through chamber with 6mm diameter approximately 15 millimeters distance brings a constant jet of fluid (symbolized by a blue arrow) with the disinfectant in a direction plumb to the membrane (1). The membrane allows molecules of the disinfectant mainly pass through . These molecules put a pathway in the electrolyte liquid (2) to the working electrode (3) back. The working electrode (3) is of precious metals (gold or platinum) so they do not corrode. The working electrode (3) is with a very small but accurate electrical voltage.

Function of the cleaning device at the amperometric sensor

In the membrane-covered amperometric sensor, the working electrode is separated from the water and disinfectant by a most sensitive membrane. A cleaning device is not realizable. This membrane may be by substances, which are located in water, be contaminated. This contamination holds the molecules to be measured back and reduces the sensitivity of the measurement. Caused by the membrane, a membrane-covered amperometric sensor is sensitive to pressure. For some disinfectant there is the possibility, carry out the measurement without membrane. The missing membrane leads to a pressure stability of the sensor. At the same time this case, the working electrode is exposed, so that the surface can be cleaned mechanically.

Sometimes it really depends on the size!

Thoughts on the raw water tank. Usually he leads a lonely existence, the raw water tank. No one wanted him, now the overflow channel makes it necessary. Previously, yet everything was so easy, now you have to make a head, when the gray box in the earth needs a new water. Sometimes, the box is also suspected, just drink the water away. The necessary "selection" of things, that arrive in the tank as litter of the overflow, not exactly stimulates to unbridled enthusiasm. It seems so simple: "A lot of (tank volume) helps a lot!“, as so often in life, it is then not so simple.
