Abstract

The invention discloses an ultrasonic flowmeter, which comprises a pressure-bearing shell and multiple sets of transducer assemblies, the pressure-bearing shell is connected with a fluid pipeline, and the pressure-bearing shell can withstand a high pressure of 42 MPa; the multiple sets of transducer assemblies along the bearing The circumferential distribution of the pressure shell forms multiple channels, and the larger sound path can ensure accurate and efficient measurement; the adjacent two sets of transducer components are distributed along the axial direction of the pressure shell, which can form different channels in the pressure shell. The cross-section reduces the impact of the flow state in the pressure shell on the measurement accuracy and improves the overall measurement accuracy; each set of transducer components includes two ultrasonic transducers with an angle of 50 to 120 degrees, ensuring that one ultrasonic transducer The emitted signal can be received by another ultrasonic transducer, and the two ultrasonic transducers are alternately used as the transmitting end and the receiving end.

Description

technical field [0001] The invention relates to the field of flow measurement, in particular to an ultrasonic flowmeter. Background technique [0002] Ultrasonic flow meters are instruments that measure flow by detecting the effect of fluid flow on ultrasonic beams. Ultrasonic flowmeters are more accurate and stable flowmeters for measuring fluids. Many occasions that require high-precision measurement such as natural gas custody transfer, energy, and environmental protection will choose ultrasonic flowmeters. [0003] The existing ultrasonic flowmeter is installed and used in the pipeline. During the measurement process, due to the continuous change of the flow state of the fluid, large flow fluctuations are generated, resulting in low measurement accuracy of the flowmeter. At present, the measurement of high-pressure medium, especially the measurement of high-pressure gas medium, is relatively weak, and most of the existing ultrasonic flowmeters are used for low-pressure ...
