Description

Technical Field

[0001] The utility model relates to the technical field of ultrasonic flowmeters, in particular to an ultrasonic flowmeter with a protective structure. Background Art

[0002] An ultrasonic flowmeter is an instrument that uses the change in the propagation speed of ultrasonic waves in a fluid to measure fluid velocity and flow rate. It calculates the fluid velocity and flow rate by measuring the difference in propagation time between ultrasonic waves in a stationary medium and in a flowing medium, as well as the propagation time of ultrasonic waves traveling downstream and upstream.

[0003] Common ultrasonic flow meters generally have anti-drop pads installed on the surface of the flow meter to provide additional protection, and use protective covers to protect sensitive components on the flow meter. Rubber blocks are installed on the surface to provide cushioning when the sensitive components of the flow meter are impacted, reducing the possibility of damage.

[0004] Existing solutions generally install a protective cover on a rubber block on the outside of the sensitive components of the flow meter to reduce damage caused by accidental drops or impacts. However, when the protective cover and the rubber block are impacted, the vibration will be transmitted to the sensitive components of the ultrasonic flow meter. The protective cover and the rubber block can only protect against impacts, and the vibration generated by the impact will still cause the transmitter and receiver to vibrate, making the transmitter and receiver easily damaged.
