4.3 Valves
Control valves or shut-off valves should always be installed downstream from the sensor
to assure that the pipe is always full of liquid.
Downstream, the minimum recommended distance to a disturbing element is 5 x DN.
4.2.1 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 shorter, readings may be unstable.
