Use a double-flange device to measure the oil-water interface; must the interface be located between the two pressure tapping points? How is the location of the pressure tap determined?
This post was last edited by ylb913 on 2016-11-29 at 12:12; two pressure tapping points are required, one at the top and one at the bottom of the interface. The measurement range depends on the height range that can be controlled via the interface; generally, the range for measuring liquid levels is in multiples of 200 + 300, with the unit being millimeters. Such as 500, 800, 1100, 1400, 1700, 2000…; these actually represent a series of glass level gauges. Double flange versions do not have to follow this series.
Generally, a glass tube level gauge or sight glass is added
As long as the interface is between the two pressure tapping points, with the normal interface being located in the middle of them; as for how much space there should be above and below, that depends on the process requirements
The boundary position is between the two pressure tapping points; however, how to determine the location of these tapping points depends on the process
Then, if I use a float level gauge, are there such requirements as well?
