CONTROLLED MEDIUM PRESSURE MEASUREMENT Russian patent published in 2014 - IPC G01L9/00 

FIELD: instrumentation.

SUBSTANCE: invention relates to active nondestructive control and can be used for controlled medium pressure measurement. Proposed method comprises pressure oscillation signal measurement by transducer, conversion of signals via ADC and registration of received digital signals. Note here that signal is transmitted to ADC to generate digital signal in dimensionless units while conversion in pressure dimension is executed by two U-like pressure gages tuned to measure maximum pressure by one arm and minimum pressure by another arm. In case maximum pressure is measured check valve transmits fluid level difference towards atmosphere and suppress towards measured medium. In case minimum pressure is measured, it transmits towards measured fluid and suppresses towards atmosphere. Software of computer converts sound change digital signal into pressure in dimensionless units and dimensionless units in dimension of pressure or velocity.

EFFECT: accurate and comprehensive measurement.
