A kind of level measuring method of closed pressure vessel measuring device, which is characterized in that steps are as follows: S1: after every
First sensor component is set at plate minimum liquid level h1, second sensor component is set at the vertical liquid level h2 of rear bulkhead, rear
3rd sensor component is arranged in partition top；
S2: air cushion cabin minimum liquid level h1, vertical liquid level h2 are measured by first sensor component and second sensor component
Pressure P1, P2 at place, vertical drop Δ h=h1-h2, then according to P1-P2=ρ g Δ h, fluid density ρ in the dunnage that can bring about the desired sensation；
S3: air cushion cabin upper gas pressure P0, air cushion cabin upper gas pressure and gas are measured by 3rd sensor component
Pressure is equal at highest liquid level h in dunnage, then according to P1-P0=ρ gh, it can be seen that highest liquid level h in air cushion cabin.
The utility model uses the sensor of three corresponding ranges, is arranged in container outer wall different location, measures in container
The pressure of different height carries out simple programming conversion using pressure calculation formula, fluid density and continuous in out-put container
Liquid level, to complete the real time monitoring of fluid density and liquid level in container.In addition, can directly hold when sensor degradation
Malfunction elimination is completed on the outside of wall and is more changed jobs, and is avoided detection with pressure, is improved operating safety factor.Meanwhile being arranged on socket
Dredge flush-through connection, can periodic flushing sensor proximity glutinous absurd creature, avoid the measurement accuracy for blocking or causing sensor.This reality
Density and liquid level in closed container can be measured in real time with novel, and easy to maintenance, avoid warehouse entry with pressure, have preferable practical
Property.
