Embodiment Construction

[0030] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only the parts related to the present invention are shown in the drawings but not all of them.

[0031] see Figure 1 to Figure 6 , The embodiment of the present invention provides an ultrasonic flowmeter, which is suitable for measuring liquid or gas, such as the detection and measurement of oil field wellhead gas, high-pressure natural gas, and process fluids in industries such as energy and environmental protection.

[0032] The ultrasonic flowmeter comprises a pressure-bearing housing 2 and at least one set of transducer assemblies.

[0033] The pressure-bearing shell 2 is connected to the fluid ...

Abstract

The invention discloses an ultrasonic flowmeter. The ultrasonic flowmeter comprises a bearing shell and at least one set of transducer assembly, and the bearing shell is connected with a fluid channel; each set of transducer assembly comprises two ultrasonic transducers, each ultrasonic transducer comprises a transducer base and a transducer probe, each transducer probe comprises a probe protection shell made from metal, one end of each probe protection shell is connected with the corresponding transducer base, and the other end of each probe protection shell is provided with a metal matching layer and is inserted into the bearing shell through a mounting hole in the bearing shell. The pressure bearing capacity of the probes is improved through the bearing shell, the probe protection shells and the metal matching layers, the probes can bear the pressure of 42MPa, a complicated decompression technology is avoided, and the cost is saved.

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 in the pipeline. When the pressure in the pipeline is high, the transducer will be damaged due to high pressure, resulting in medium leakage; in order to measure high-pressure fluid, the production process will be changed in some occasions. For high-pressure fluid Perform depressurization treatment, and then measure again, the depressurization process is complicated, time-consuming and laborious, and the cost of ...
