Cold high-pressure fractionator float level gauge for hydrogenation unit
Thread Content
The working principle of the cold high-pressure float level gauge in hydrogenation units, which is used to measure the interface between oil and water; what impact does changes in oil density have on this measurement?
Buoys are definitely affected by density! As the density increases, buoyancy increases as well, resulting in a liquid level reading that is higher than the actual level!
If the density of the oil is close to that of water, what is measured is the liquid level, not the interface
All floating tanks operate on the same principle; their design takes into account the density of the medium being measured, and when the density changes, recalibration is necessary
Changes in density would affect the measurement results of the float, right? It is calculated based on ρ*g*h anyway.
