Measurement issues of differential pressure level gauges on low-temperature tanks
Thread Content
If the liquid level in a cryogenic storage tank is too high, and both the high-pressure and low-pressure sides of the level gauge are submerged in liquid, can a differential pressure level gauge still measure the level?
If the liquid level in a low-temperature storage tank is too high, and both the high-pressure and low-pressure sides of the level gauge are submerged in liquid, can a differential pressure level gauge still be used for measurement? No, the positive pressure tube is located in the liquid, while the negative pressure tube is at the very top ； In addition, a side fill valve is also installed at the upper part of the storage tank; both upper and lower purging can be carried out with reference to the measurements.
