How is the gas phase in liquefied gas balloon tanks measured? What type of measuring instrument will be used for measurement? How effective is it?
The gas phase is generally not used for metering; a balance tube is installed in the gas phase to achieve balance. If measurement is required, an orifice plate flow meter can be used for it.
The gas phase is generally not measured, and moreover, the gas phase in spherical tanks also changes
It has been clearly explained upstairs: this gas phase is there only to achieve equilibrium. If a meter is installed, you need to take into account the issue of meter reversal.
By \"owner,\" does it refer to the measurement in the gas-phase return pipe during quantitative loading with a flow meter? If so, an orifice plate flow meter can be used for this purpose. However, penalties for overloading liquefied gas are quite strict these days; it is recommended to use a load cell-based quantitative loading system.
What needs to be measured is, I assume, the mass of the gas phase! Calculate the volume based on the tank capacity table and the liquid level, then determine the density by referring to a table, and thus the calculation can be completed. Trade settlement is more accurate and reliable than flow meters.
