3.4 Valves
Control valves or stop cocks should always be installed downstream from the sensor to
assure that the pipe is always full of liquid.
3.3 Mixtures
If liquids of different conductivities are mixed it is necessary to install the sensor a
minimum of 50 x DN from the point of mixture in order to obtain a uniform conductivity of
the liquid and stabilize the readings.
If this distance is less, the readings may be unstable.
50 DN
3.5 Pumps
Pumps should be mounted upstream from the sensor to avoid the suction part of the pump
(vacuum).
