WIPO Patent Application WO/2024/027777
Kind Code:
A1
Abstract:
Provided in the present application is an ultrasonic flowmeter, comprising a body, transducer assemblies, limiting devices and spacer assemblies. The body is provided with an accommodating cavity therein, a side wall of the body is provided with fixing holes in communication with the accommodating cavity, and one transducer assembly, one spacer assembly and one limiting device are located in each fixing hole; the transducer assembly is in sealed connection with an inner peripheral wall of the fixing hole, a first end of the transducer assembly faces the accommodating cavity, a second end of the transducer assembly faces the limiting device and is in clearance fit with the limiting device, the spacer assembly is sleeved on the second end of the transducer assembly, and the limiting device comes into contact with the transducer assembly by means of the spacer assembly; the limiting device is fixedly connected to the inner peripheral wall of the fixing hole; and the spacer assembly comprises a spacer, and at least one face of the spacer is provided with one or more protrusions. In the ultrasonic flowmeter in the embodiments of the present application, the provision of spacer assemblies reduces the effect of clutter from the body on the transducer assemblies, thereby improving the measurement precision of the ultrasonic flowmeter.
