Regarding the issue of inaccurate measurement of liquid ammonia!
Thread Content
The company’s ammonia recovery rate is calculated inaccurately, and the main reason for this is a measurement issue: there is a discrepancy between the two liquid ammonia flow meters (the value indicated by the outlet meter is higher than that indicated by the meter connected to the storage tank). Has anyone encountered this problem? How can it be resolved? Can the flow meter provide accurate corrections? Pipeline transportation (about 3 kilometers)
Ammonia flow meters are most sensitive to vaporization issues; once vaporization occurs, it leads to measurement errors. The process should consider how to avoid gasification.
It’s because liquid ammonia isn’t delivered continuously; vaporization is the main reason, I guess! There has still been no solution!
First, close some of the valves behind the instrument to increase the pressure in that area and prevent too rapid pressure loss. Second, take insulation measures to prevent vaporization
Do you mean the gauge behind that is the one for the savings tank? Can I add you on QQ to learn more from you?
