DEVICE FOR MEASURING RATE OF GAS-LIQUID FLOW Russian patent published in 2007 - IPC G01F1/74 G01F1/66 G01N22/00 E21B47/10 

FIELD: measuring technique.

SUBSTANCE: device comprises three open radiowave cylindrical high-frequency resonators for measuring relative concentration of flow components. The resonators are axially aligned inside the tubular metallic housing. Each resonator is made of a short-circuited conductor shaped into a rectangular meander and is provided with two mutually perpendicular input-outputs. The device is additionally provided with controlled high-frequency generator and commutator, two output amplifiers, controller of the flow regimes, and six shielded receiving-transmitting channels connected with the corresponding inputs-outputs of the resonators and inputs of the computing control unit. The end sections of the pipe are provided with short-circuited arresting turns, and short-circuited arresting-separating turns are interposed between the resonators.

EFFECT: enhanced precision.
