METHOD AND DEVICE FOR MEASURING FLOW OF GAS-LIQUID STREAM Russian patent published in 2006 - IPC G01F1/66 

FIELD: measuring equipment engineering, possible use when measuring flow of natural gas excavated at gas condensate deposits and containing liquid hydrocarbon phase in drop or spray form.

SUBSTANCE: device consists of frequency control block, swaying frequency generator, two cylindrical resonator, two detector sections, block for measuring and processing frequency, indication block, two connecting wave ducts, wave duct branch box. Into second open resonator excitation body is introduced, made in form of a set of resilient radial plates. Measurements are performed as follows: the flow is let through two open cylindrical resonators. Shift of frequencies of both resonators, working on oscillation types TM_mpq with even longitudinal index q, is measured. On basis of first resonator frequency shift, density of gas-liquid flow is determined. On basis of second resonator shift, speed pressure is determined. On basis of received data, volumetric and mass flows of gas-liquid flow in pipeline are determined.

EFFECT: increased flow measuring precision.
