Application Example 1
In this application we have a system consisting of (4)
multivariable tank level gauges connected to (2)
DPM-100 Modbus scanners 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.
