5) Open both plug at seal pot. 7) Remove tubing at high side of manifold. Level measurement using hydrostatic pressure. You may upload documents including specification sheets, Toolkit files or other information. X = Liquid level span Y = Zero level offset D = Wet leg height GL = Specific gravity of liquid in tank GS = Specific gravity of fill liquid SPAN = (X) (GL) = (40) (1) = 40 LRV = (Y) (GL) (D) (GS) = (5) (1) (45) (2) = 5-90 = -85 feet). Apply pressure as per calculation when level equivalent to zero. So I suggest to my collegues (the instrument technicians) to configure LRV as -236 and URV as -91 because the smart transmitter can accept the negative pressure but they didn't agree with me and they said that they have an old method: in fact, to eliminate the zero: they will consider LRV = 236 and URV = -91 - (-236) = 145 (span). Flow Sizing and Selection. Intelligent Communicator DCR3000 The LRV distance should comfortably exceed the URV span. Also question is, how is DP transmitter level calculated? For a dP level transmitter, the upper range value (URV) and lower range value (LRV) are defined as: URV = liquid specific gravity (SG) the distance between 100% and 0% (h 100%) + LRV; and. Calculation distance between both flanges is 1835 mm and density of fluid in tank is 1.15. transmitter is mounted below the high side flange. 1) Point level sensors are used to mark a specific single liquid height.
