Problems solved by technology

[0002] Existing positive displacement flowmeters can be divided into waist wheel flowmeters, oval gear flowmeters, scraper flowmeters, double rotor flowmeters, rotary piston flowmeters, etc., which have the advantages of high measurement accuracy and no influence of installation pipeline conditions on measurement accuracy. It can be used for the measurement of high-viscosity liquids and has a wide range; but the disadvantages are that the structure is complex, the volume is large, the type of medium to be measured, the caliber, and the working state of the medium are limited, and the noise and vibration are large during operation, and it is easy to jam and wear. High failure rate and difficult maintenance, most instruments are only suitable for clean single-phase fluid

Abstract

A flowmeter with flexible rotor in ring type consists of main body, liquid inlet and outlet, end covers, central rotation shaft, ring type of metering chamber formed between internal wall of main body and external wall of rotation shaft, multiple rotor containers, multiple flexible rotors, metering space with set volume, liquid inlet - outlet guide in thickness being less than or equal to thickness of said metering chamber. Its design accuracy can be up to plus or minus 0.1 %.

Description

technical field [0001] The invention relates to an oilfield metering instrument, in particular to an annular movable rotor flowmeter. Background technique [0002] Existing positive displacement flowmeters can be divided into waist wheel flowmeters, oval gear flowmeters, scraper flowmeters, double rotor flowmeters, rotary piston flowmeters, etc., which have the advantages of high measurement accuracy and no influence of installation pipeline conditions on measurement accuracy. It can be used for the measurement of high-viscosity liquids and has a wide range; but the disadvantages are that the structure is complex, the volume is large, the type of medium to be measured, the caliber, and the working state of the medium are limited, and the noise and vibration are large during operation, and it is easy to jam and wear. The failure rate is high and maintenance is difficult. Most instruments are only suitable for clean single-phase fluids. Contents of the invention [0003] Th...
