Turbidity sensors may also be installed directly into a flowing pipe system provided that the water
does not contain a lot of entrained air. It is best to install the sensor in a vertical pipe section with water
flowing upward. This assures that air pockets cannot develop at the sensor. If installed in a horizontal run
of pipe, place the sensor at the 3 or 9 o’clock position. Never mount the sensor on the top or bottom of
the pipe. It is also good practice to install a bypass system around the sensor for maintenance and
calibration purposes. Figures 8 and 9 show a typical installation and assembly.
