Abstract
The invention discloses a flowmeter for gas and liquid and belongs to the technical field of flow measurement. The flowmeter for gas and liquid solves the problem that under the condition that the mass of gas is similar to the mass of liquid, the error is large when the flow of a single-phase fluid is measured. According to the flowmeter for gas and liquid, a pressure sensor 2 is arranged at the position of an end mouth of the flowmeter 1 for gas and liquid and is connected with the gas-liquid mass flowmeter converter 3 through a circuit, the pressure sensor 2 can be arranged at the position of the front end mouth or the rear end mouth of the flowmeter 1 for gas and liquid, can also be arranged on an internal measurement pipeline of the flowmeter 1 for gas and liquid, can also be arranged on an external pipeline connected with the flowmeter 1 for gas and liquid and is connected with the gas-liquid mass flowmeter converter 3 through the circuit, and a gas and liquid mixer 4 and the pressure sensor 2 can be arranged on an external pipeline connected to the front end of the flowmeter 1 for gas and liquid and are connected with the gas-liquid mass flowmeter converter 3 through a circuit. By the adoption of the flowmeter for gas and liquid, the mixture liquid flow measurement accuracy is improved.
Description
One, technical field the invention belongs to the field of measuring technique of flow, particularly relates to a kind of by the mass flowmeter of gaging pressure differential pressure.
Two, background technology is current, along with scientific and technical development, mass flowmeter manufacturer has released the gas-liquid mass flowmeter that can measure gas-liquid mixture fluid, and it can measure the mass rate of gas-liquid mixture fluid and the operating mode density of volumetric flow rate and gas liquid mixture.But be of limited application, because the fluid larger or less to gas-liquid mass ratio measured monophasic fluid flow error less, in the time that gas-liquid mass ratio is tending towards close, measure monophasic fluid flow error just very large.
Three, summary of the invention the object of this invention is to provide a kind of gas-liquid flowmeter, when having solved gas-liquid mass ratio and being tending towards close, measure the large problem of monophasic fluid flow error, it is provided with pressure transducer in gas-liquid mass flowmeter port, and is connected with gas-liquid mass flowmeter converter circuit; Pressure transducer can be arranged on gas-liquid mass flowmeter front port place or rear port place, also can be arranged on the pipeline of gas-liquid mass flowmeter internal measurement, can also be arranged on the outside pipeline connecting of gas-liquid mass flowmeter, and be connected with gas-liquid mass flowmeter converter circuit; Air and liquid mixer, pressure transducer can be arranged on the outside pipeline connecting of gas-liquid mass flowmeter front end, and are connected with gas-liquid mass flowmeter converter circuit, have improved fluid-mixing flow measurement accuracy.
Four, brief description of the drawings Fig. 1 is built-in pressure transducer gas-liquid flowmeter structural representation;
Fig. 2 is external pressure transducer gas-liquid flowmeter structural representation.
Five, embodiment is described further gas-liquid flowmeter of the present invention below in conjunction with Fig. 1 and Fig. 2, is provided with pressure transducer 2 in gas-liquid mass flowmeter 1 port, and is connected with gas-liquid mass flowmeter converter 3 circuit; Pressure transducer 2 can be arranged on gas-liquid mass flowmeter 1 front port place or rear port place, also can be arranged on the pipeline of gas-liquid mass flowmeter 1 internal measurement, can also be arranged on the outside pipeline connecting of gas-liquid mass flowmeter 1, and be connected with gas-liquid mass flowmeter converter 3 circuit; Air and liquid mixer 4, pressure transducer 2 can be arranged on the outside pipeline connecting of gas-liquid mass flowmeter 1 front end, and are connected with gas-liquid mass flowmeter converter 3 circuit.So only gas phase mark condition density manually need be inputted to gas-liquid mass flowmeter converter 3, can calculate gas phase operating mode density; If gas phase is wet saturated steam, by pressure and density input gas-liquid mass flowmeter converter 3, also can calculate gas phase operating mode density; If gas-liquid medium is single component, as wet saturated steam, directly calculate liquid and gas operating mode density by gas-liquid mass flowmeter converter 3; By mixed flow regime density, gas phase operating mode density and the liquid phase operating mode density of gas-liquid fluid, by the calculation procedure of gas-liquid mass flowmeter converter 3, can calculate the percent by volume of gas-liquid fluid, the mixing quality being recorded by gas-liquid mass flowmeter 1 again and volumetric flow rate, can calculate gas phase and liquid phase volume and mass rate.
