METHOD FOR REGISTERING THE REMOVAL OF SOLID FRACTIONS IN A GAS STREAM Russian patent published in 2022 - IPC G01N15/06 

FIELD: gas industry.

SUBSTANCE: invention relates to the field of monitoring the operation of gas wells. A method for registering the removal of solid fractions in a gas stream, based on the reception of acoustic signals by a piezoelectric sensor installed on the outer surface of the pipe from collisions of solid fractions with the inner surface, consists in the fact that high frequencies are isolated from the received signal with a boundary corresponding to ultrasonic waves capable of propagating in the walls of pipes with a given range of wall thicknesses, then quadratic detection is carried out, then low-frequency industrial noise and the original carrier frequencies are excluded from the detection result, then the received amplitude modulation signal is detected and measured, then the measurement result is declared proportional to the mass rate of removal of solid fractions.

EFFECT: increase in the reliability of the data obtained when registering solid fractions in a gas stream under conditions of industrial interference.
