Two-channel measuring devices

PROline Prosonic Flow 93 has two measuring channels which are independent of one
another. In other words, the transmitter supports the simultaneous operation of two sen-
sor pairs at two individual measuring channels. In doing so, the resources of the trans-
mitter are split evenly between the two channels.
This ability of the transmitter can be used in many different ways:
• For two-channel measurement
• For two-path measurement
The transmitter can output the measured values of both channels either individually or
arithmetically linked (as total, difference or mean).
3.3.1

Two-channel measurement

In the case of dual-channel measurement, the measured values of two independent
measuring points are determined and processed by one transmitter.

If required, the measured values of measuring channel 1 and measuring channel 2 can
be arithmetically linked together. The following possibilities for outputting measured val-
ues are suitable for dual-channel measurement:
• Individual output of measured values from channel 1 and 2
• Total of measured values from channel 1 and 2
• Difference of measured values from channel 1 and 2
The measuring device supports the individual configuration of the measuring channels
and the independent setting of the display and outputs. As a result, the sensor type and
type of installation, for example, can be selected and configured separately for both
channels.
