The average temperature of the gas at the time in the tank is determined in degrees K.

A method for controlling a monitoring unit for the residual supply time for the gas present in a pressurized container includes associating with a plurality of angular positions respective residual time values in accordance with a selected flow; measuring the angular position of the control element by means of a magnetic tunnel effect angle sensor. A residual time value is determined in accordance with the selected flow corresponding to the angular position of the rotary control element; measuring an intensity of the magnetic field by means of the magnetic tunnel effect angle sensor TMR. A limit intensity value is defined for the magnetic field. A display device displays the residual time value in accordance with the selected flow only if the intensity of the magnetic field measured is less than the limit value.

A release gas capture and repurposing system and method designed for use in oilfield operations. The system includes a collection assembly that is attached to oilfield equipment to gather gas released during operation. Once collected, the release gas is channeled to a pressure vessel where the release gas is securely captured. A meter is installed in fluid communication with this vessel, which serves to measure the amount of captured release gas. The system also incorporates a conduit network that prevents the release of gas and condensate vapors to open-top tanks by directing the captured release gas to a designated location. Further, the system includes an emissions calculator that estimates a reduction in greenhouse gas emissions based on a quantity of release gas captured and redirected by the system relative to conventional methods and quantified by the meter.
