Gentlemen, both single-chamber equilibrium vessels and double-chamber equilibrium vessels can be used to measure the level of liquid in a drum. What are their respective advantages and disadvantages?
It should be; when used in a drum, a two-chamber design is better. The difference between the two lies in the fact that in a single-chamber balance vessel, the temperature of the medium on the low-pressure side differs from that on the high-pressure side, which leads to measurement errors. It is recommended that the medium for high-pressure and low-pressure measurements be under one specific operating condition, as this yields more accurate results.
Whether it is a single-chamber or dual-chamber design, the pressure measurement function remains the same. . . Wearing one pair of underpants versus wearing two – what are the advantages and disadvantages for waterbirds, do you think? . In single-chamber mode, the temperature difference across the differential pressure gauge can be ignored. . . Only a fool would make the pressure guiding tube too short, resulting in a temperature difference of 50°C or 100°C between its two ends. . . Even a difference of 100°C results in only a 2% temperature uncertainty error; in other words, if the differential pressure range is 1 meter, then a 100°C temperature difference leads to an uncertainty error of approximately 2 centimeters. {:2_32:}
