Discussion: With a throttle orifice plate, two differential pressure transmitters are used – one to measure high flow rates and the other to measure low flow rates. How can these two differential pressure transmitters be switched for measurement within a DCS system?

Set a condition for DCS: display A if the flow rate is greater than a certain value, display B if it is less than another value, and hide it if the flow rate does not meet that threshold.

Can orifice plates be used this way too? The range ratio of the orifice plate itself isn’t high; is this meaningful?

There are two transmitters, displayed on the DCS – why switch?
