Function: A monodirectional
possible directions (raise OR lower measured value).
Application: This affects, for example, a disinfection process, in
which chlorine is added to water. The incoming water has a
chlorine concentration of 0 ppm and is to be adjusted to 0.5 ppm
by the addition of sodium-calcium hypochlorite. The addition of
sodium-calcium hypochlorite raises the measured value.
