Answer / sam

Ok I think I understand what you are asking. In most SMART
transmitters you have a digital indication on the
transmitter and you want to change what is displayed on this
indicator. You also said that you have changes the unit of
measure inside the transmitter with the HART, and this also
changed the UOM that is displayed.

There is a different parameter that you need to modify to
change the display. The parameter is normally something like
"set disply" or something like that.
Be aware that it will only display UOM or percentage or
display a switching between the two. What ever you have set
your UOM to inside the transmitter, will be displayed on the
indicator as the UOM. You cannot set the UOM to mmH2O inside
the transmitter and then display mBar on the display.
Also note that for a level application this display is
normally set to percentage and not UOM. If the operator look
at it he needs to see % level and not mm level. In a
pressure, flow or temp applications you want this display to
indicate UOM again.
Good luck

First of all,parameter's which need to be diagnostic in
transmitter with any of communicator will be in percentage .
Like for flow eg: Kgs,temp eg:cc fh level eg: % ,pressure
psi or bar.

1.what is controller proportional gain 2.what is the controller intergral action time. 3.A proportional plus derivative controller that has a proportional band of 20% and a derivative action time of 0.1 minutes. Construct the shape of the output waveform for the triangular input if the input rises and falls at the rate of 4 units per minute.

HELLO FRENDS ,, I M IN THE MIDST OF TROUBLE .. JUST LITTLE HELP ME... SUPPOSE ,, I HAVE A CLOSE VESSELE TANK ( HEXANE MEDIA ) ,, I M USING ROSEMOUNT 2051 DPT FOR LEVEL APPLICATION .. ITS CALIBRATE RANGE IS.. . 0 TO 950 MMH20 ..I DID CALIBRATED DPT WITHOUT REMOVING IMPULSE LINE OF HIGH AND LOW TAPPING.. & WITHOUT DISTURB 3 WAY MANIFOLD..!!! BUT ,,, DURING CALIBRATION I SELECT RANGE BY HART LRV IS 900 MMH20 & URV IS 1300 MMH20 ,, BUT ,TANK LEVEL SOMETIMES 100 % AT 1100 MMH20 , SOMETIMES 1300 MMH20 ..IN THIS CONDITION .. WHOLE LOOP FAILED ,, MAIN THING IS THAT ,, HOW TO CUSTOME RANGE SELECT ?? AND IF I USED RANGE OVER THE ORIGINAL CALIBRATE RANGE ,,,THEN WHAT ERROR WILL BE COME ??? HOW TO ZERO CALIBRATION OF DPT... HOW TO ZERO TRIM BY MANIFOLD ?? AND FOR TANK LEVEL PURPOSE ... WHICH UNIT I CAN USE ??? IS THERE ANY CALCULATION OR CALIBRATION .. IF YEH .. THEN PLZ JUST GIVE ME CALIBRATION STEPS FOR DPT.. THANKS YOURSSSSSSS
