LRV and URV of Interface Level Transmitter

USE “SEARCH” TAB ON the top right side FOR ALL INSTRUMENTATION RELATED TOPICS

I WILL DESCRIBE A SIMPLE PROCEDURE TO DETERMINE THE LRV AND URV OF INTERFACE TYPE LT CAPILLARY TYPE

LET US CONSIDER THE INTERFACE AS BELOWLT

FOR INSTANCE THE TAP TO TAP MEASUREMENT OF CAPILLARY FLANGES BE 3400mm WC (LEVEL TO BE MEASURED), THE HIGHER SPECIFIC GRAVITY LIQUID BE WATER OF SPECIFIC GRAVITY 1.05 (YOU CANNOT EXPECT 1.00 BEACAUSE IT IS NOT MINERAL WATER INSIDE TANK) AND LOWER SPECIFIC GRAVITY LIQUID BE CRUDE OIL OF 0.876,THEN INTERFACE MEASUREMENT CAN BE DONE USING A SIMPLE WAY AS EXPLAINED BELOW,

  1. INSTALL THE LT AND POWER UP THE TRANSMITTER,ISOLATE THE PROCESS AND VENT TO ATMOSPHERE AND DRAIN THE PROCESS, THE TRANSMITTER WILL SHOW A VALUE LIKE -3042mmWC (EXAMPLE) DUE TO PRESSURE OF SILICONE OR GLYCOL FILLED INSIDE CAPILLARY OF HP AND LP,NOTE THIS VALUE

  2. FOR LRV(0% INTERFACE LEVEL  4 mA) CONSIDER THE TANK OF HEIGHT 3400 FULLY FILLED WITH CRUDE OIL OF SPECIFIC GRAVITY 0.876,THAT IS THERE IS NO WATER IN TANK THEN LRV CAN BE FOUND AS LRV=3400*0.876 PLUS -3042 WHICH WE GOT DURING STEP 1 , THAT IS     LRV=(3400*0.876)+ (-3042 ) =2978.4-3042=  -63.6 mmWC

  3. FOR URV(100% INTERFACE LEVEL 20mA),CONSIDER THE TANK FULLY FILLED WITH WATER OF SPECIFIC GRAVITY 1.05,THAT IS THERE IS NO CRUDE IN THE TANK OF HEIGHT 3400 URV CSN BE FOUND AS FOLLOWS URV=3400*1.05 PLUS (-3042)                 =3400*1.05+(-3042)

    =3570-3042=528mmWC

  4. THUS LRV= -63.6 mm WC

  5. URV= 528 mm WC

NOTE THAT THIS IS FOR INTERFACE LEVEL MEASUREMENT DONT CONFUSE THIS WITH DIRECT LEVEL MEASUREMENT
