Installation and maintenance
Installation: To ensure the real measurement result, data distortion caused by air bubble or dead water in conductance cell should be avoided. The installation should be performed strictly according to the following drawing:

Conductivity-meter6

Notes
1. The electrode should be installed at a lower location in the pipe where the flow speed is steady and air bubbles are seldom generated.
2. No matter the conductance cell is horizontally or vertically installed, it should be deeply inserted into the moving water.
3. The conductivity/Resistivity signal is weak electronic signal and its collecting cable should be separately installed.
When threading cable joint or connecting terminal board is used, to avoid wetting interference or breakdown of measurement unit circuit, they should not be connected to the same group of cable joint or terminal board with the power or control line.
4. When the measurement cable needs to be lengthened, it’s recommended to use the cable provided by the original manufacturer, and the joint should be subject to reliable damp-proofing insulation disposal. When a longer distance is involved, the length of the cable (<30m) should be agreed on before delivery, and if the length is over 30m, a transmitter should be used.

Electrode Maintenance
1. The electrode cell should not be soaked in strong acid or alkali liquid, and the platinum black coating should not be wiped or it will lead to electrode surface damage and the constant and response capability will be affected. The right way should be: when the electrode is dirty, soak it in 10% dilute hydrochloric acid for a short while, then rinse it with pure water to keep the surface clean.
2. The measurement cable is special cable and should not be changed at will or it will cause significant error.
