Derive
the used amount from a value obtained by a level or weight-measuring transmitter
using the reverse calculation function of the M2UDS Reverse Transmitter.
Details: The function
of a Reverse Transmitter is to take an input signal, invert it and produce
an inverted output signal. For example, an inverted input signal of 100%
produces an output signal of 0% and vice-versa. i.e. Output % = 100% - Input
%
In the graph, the dotted line is the output value of a sensor measuring
the quantity remaining in the tank. The unbroken line is the output value
calculated by the Reverse Transmitter, which shows the inverse value of
the sensor and therefore indicates 'how empty the tank is', i.e. the amount
used up since the tank was last filled to 100%. |
