Two-channel operation

The transmitter is able to operate two independent measuring channels (measuring channel 1 and
measuring channel 2). A pair of sensors is connected per measuring channel. Both measuring
channels operate independently of one another and are supported by the transmitter to an equal
extent.
Two-channel operation can be used for the following measurements:
• Two-channel measurement = flow measurement at two separate measuring points
• Two-path measurement = redundant flow measurement at one measuring point
3.3.1

Two-channel measurement

The flow is measured at two separate measuring points in the case of two-channel measurement.
The measured values of the two measuring channels can be processed and displayed differently.
The following measured values can be output for two-channel measurement:
• Individual measured values per measuring channel (output independently of one another)
• The difference between the two measured values
• The sum of the two measured values
The two measuring channels can be configured individually. This makes it possible to independently
configure and select the display, outputs, sensor type and type of installation.
