METHOD OF MEASURING FLOW RATE AND AMOUNT OF GAS MEDIUM Russian patent published in 2011 - IPC G01F1/86 G01F15/04 

FIELD: physics.

SUBSTANCE: proposed method consists in recording gas amount at supplier gas meter and consumer gas meter. Note here that measurement units are used at each said meter to determine operating time of said unit. Flow rate and amount of gas in operating and normal (standard) conditions, gas hourly average and daily average temperature and pressure. In control process, gas heat losses in transportation line are allowed for by determining current mass flow difference Δq_m(t) and current gas volume difference Δq_c(t) in normal conditions between supplier and consumer gas metering stations, as well as total losses as gas mass loss M and volume V under normal conditions. For this differences in current mass flow Δq_m(t) flows Δq_c(t) are integrated for normal conditions at control time interval τ₀.

EFFECT: higher accuracy of gas flow rate control.
