Rosemount 3051 diff pressure transmitter - programming?

[Airsporter1st]

Hi Gents,

I often encounter the above showing an alternating display of "mbar" and then "Nl/min".

Can anyone explain in simple terms how the transmitter is programmed to generate the flow from the measured deltaP?

All help much appreciated.

Paul.

First you need a Hart communicator to re-program it. But for flow measurements, the transmitter has a square-root function, based on low and high flow points.

See the manual.
