Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of flow meters, in particular to an adjustable transducer fixing frame. Background Art
[0002] The transducer is the core component of the ultrasonic flowmeter. The basic condition for the normal operation of the ultrasonic flowmeter is that the transmitting and receiving transducers are on the same straight line. The key to the installation and positioning of the transducer is that the angles of the transmitting and receiving transducers relative to the installation reference are consistent. For example, in the design of a box-type ultrasonic open channel flowmeter, the angle between the designed sound wave transmission direction and the installation reference is 45°. However, during actual installation, the processing accuracy of the larger box is difficult to guarantee, resulting in an angle deviation of the installed transducer. This difference will cause the received ultrasonic signal to weaken or the shape of the wave to change, making the ultrasonic open channel flowmeter unable to work properly. Utility Model Content
