The DULCOMETER ®
ference variable. This interference variable affects the actuating variable calculated by the
DULCOMETER D1Cb as a function of this external signal.
®
Depending of the nature of the effect on the actuating variable, it is referred to either as a
n
multiplicative interference variable or an
n
additive interference variable
The interference variables input can process digital signals up to 500 Hz.
When "commissioning", the zero point signal of the flow gauge has to be checked without flow (must
be ≥ 0).
