Calculation channels
In addition to the ultrasonic measuring channels, the transmitter has 2 virtual calculation
channels Y and Z. The measured values of the measuring channels A and B can be cal-
culated via the calculation channels.
The result of the calculation is the measured value of the selected calculation channel.
This measured value is equivalent to the measured values of a measuring channel. All
functions which are possible with the measured values of a measuring channel (totaliz-
ing, online transmission of data, storing, outputs, etc.) can also be done with the values
of a calculation channel.

Characteristics of the calculation channels
The measuring channels to be used for the calculation and the calculation function have
to be entered in the program branch
Parameter
.
It is possible to define 2 cut-off flows for each calculation channel. The cut-off flow is not
based on the flow velocity as is the case with the measuring channels. Instead, it is de-
fined in the unit of measurement of the physical quantity selected for the calculation
channel. During the measurement, the calculation values are compared with the cut-off
values and set to zero, if necessary.
A calculation channel provides valid measured values if at least one measuring channel
provides valid measured values.

Parameterization of a calculation channel
• Select a calculation channel (Y or Z) in the program branch
Parameter
.
• Press ENTER.
Notice!
The values of the current series of measured values will be deleted if the FastFood
mode is deactivated and activated again without interrupting the measurement.
The values of the current series of measured values will be kept if the measurement
is interrupted before the FastFood mode is activated again. A new series of mea-
sured values is created when the next measurement is started.
Notice!
Calculation channels are only available if the transmitter has more than one measur-
ing channel.
