I have a level transmitter with a small range of 641mm that corresponds to a level glass on a bridle. I need to mount the transmitter at grade and the taps (located on the bridle) will be mounted above it. Will I have to take the transmitter being below its taps in consideration or is this when auto zero on the transmitter comes into play? The vessel is a KO drum operating pressure of 68.2 psi. I have found conflicting information on the web.
See page 2. www2.emersonprocess.com/siteadmincenter/.../00816-0100-3206.pdf
On page 2 it says the transmitter should be mounted at or below it's taps. In their below calc there isn't any reference to a dimension if the transmitter is mounted below it's lower tap.
Also, when is Auto-Zero function to be used?
Thank you,
Ariel
