If the height of this spherical tank is 1850 meters, then
it has got to be the biggest spherical tank in the world.
It would be almost 2 Kms high. Check your numbers.

Answer / jabi

suppose the total height of tank is 18.5 mtr
LRV= 1mtr above from ground
URV= 14 mtr above from the ground(4.5mt below the top heigt)
Low pressure side total height= 13mtr

Differential pressure at LRV:
P(high)= height x SG
= 1 mtr x 0.53
= 530 mmWC
P (low)= 13 mtr x 0.53
= 6890 mmWC

LRV is equal to P(high)-P(low)
= 530-6890
= -6360 mmWC

Differential Pressure at URV:
P(high)= 14mtr x 0.53
= 7420 mmWC
P(low)= 13 mtr x 0.53
= 6890 mmWC

URV is equal to P(high)-P(low)
= 7420-6890
= 530 mmWC

Answer / ghalib

first the question is not clear,the total height of the
tank given in mtr(1850)but the 0% is above 1000mm,ok,but
100% level is 450 below upper side,(this 450 is in what-mm
or meter,pls make it clear

Answer / imran

Mr Ghalib Its 450mm below upper side.

Answer / chinna babu

LRV=(1m * 0.53) -(18.5 m *0.53)

URV= (14 m * 0.53)- (18.5 m *0.53)

Answer / imran

It is 18.50mtr

Answer / nestor

let us consider at 100% 450meters upper side so the wet leg measures:
1850 - (450 meter + 1 meter) = 1399 meter
so height(specific gravity) = 1399 (0.53) = 741.47 meter
span = URV-LRV
LRV = 1 meter(0.53) = 0.53 meter
so URV = span+LRV = 741.47 + 0.53 = 742 meter

How can i solve the problem of ROSEMOUNT 5300 guided wave level transmitter of full range? For more clearfication , another guided wave level transmitter VEGA brand have the same problem and i solved it by drain the champer from water and make "false signal suppretion" from transmitter push buttons it's configuration to tell the transmitter to avoid any built-up signal ,,, so my question how can i avoid the problem that rosemount read full range while the champer empty or any other ????
