Application Example 1
In this application we have a system consisting of (4) MTS M-Series multivariable tank level gauges
connected to (2) PD6080 displaying Product Level, Interface Level, and Average Temperature.
One of the Modbus Scanners is located next to the tanks and the other is located in the control room.
