Principle of constant current at critical compression ratio
Thread Content
The principle behind level measurement in blow-out type level gauges is the constant-flow principle based on the critical compression ratio. I would appreciate it if someone could clarify whether this compression ratio refers to the pressure ratio between the upstream and downstream of the gas shutoff element in such gauges, or rather to the pressure ratio at the interface where the gauge gas comes into contact with the fluid Thank you for the advice!
Refers to the pressures at both ends of the throttling element. In engineering, it is estimated based on the pressure inside the container and the gas supply pressure.
In a sealed container, how can one determine whether there are trace amounts of bubbles forming? Thank you!
Is the principle behind a blow-out level gauge the Bernoulli equation?
