For our custom process skids we have to provide precise measurement of pressure, temperature and flow. To this point we've not used multivariable transmitters, mostly because of our parts-stocking responsibility for our installed customer base. Are there any practical reasons why we shouldn't switch? Cost, wiring and time all seem to favor a multivariable approach for new builds. The vendors we talked to suggest we're dumb not to switch.
Send us your comments, suggestions or solutions for this problem. We'll include it in the August '10 issue, and post it on ControlDesign.com. Send visuals if you'd like - a sketch is fine. Email us at [email protected]. Please include your company, location and title in the response.
