Installation of the sensors

 

 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:

 

RO-8100

Sensor Apperance

RO-8100

 

 

Notes:
(1)The sensor should be installed at a lower location inthe pipe where the flow speed is steady and air bubbles are seldom generated.
(2) No matter the conductance cell is horizontally or vertially installed, it should be deeply inserted into the moving water.
(3) The conductivity signal is weak electronic signal and collecting cable should be separately installed. They should not be connected to the same group of cable joint or terminal board with the power line.
(4)When the measurement cable needs to be lengthened, it’s recommended to use the cable provided by the original manufacturer, 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.
