You need to do two things here. Your Rosemont is probably 4-20mv output. You need a calibrator to emulate that output, (or whatever output it is), to calibrate your controller/recorder. Basic stuff.

http://www.einstrumentsgroup.com/

Then I've made up a calibrator for the Rosemont itself. A pump up bulb, with shutoff, a calibrated gauge of the range I need, to the high and low pressure inputs of the Rosemont. So, then you've calibrated the whole system.

Tell me if I could have explaned this in any less words. I'm aiming for an "economy of words" program these days.

Rosemount transmitters are usually delivered with a manual or a CD that has a manual. You'll find calibration procedures in it.

If you don't have a manual, you can get one from their website.

In addition to the above, some device for determining the zero and span of the instrument will be required. Most likely this will be something like a tape measure, and the instrument will be set-up during the commissioning-with-water period on this project.
