Description

Technical Field

[0001] The utility model relates to the technical field of closed pipeline flow measurement, in particular to an adsorption and fixing device based on a handheld ultrasonic flowmeter probe. Background Art

[0002] In closed pipe flow measurement, a handheld ultrasonic flow meter probe is usually used for measurement. When the handheld ultrasonic flow meter probe is in use, after the probe finds the optimal point of the signal, the handheld ultrasonic flow meter probe needs to be fixed on the pipe wall for measurement.

[0003] The existing handheld ultrasonic flow meter probe is generally fixed in a way that it has a built-in magnetic attraction. After the probe finds the optimal point, the probe is attached to the wall of the measured pipe through magnetic attraction. The magnetic attraction strength may decrease with the aging of the magnet or the difference in the material of the pipe wall, resulting in position slippage, making the measurement signal unstable and affecting the accuracy of the measurement data. The built-in magnetic attraction method is only applicable to metal pipes. For non-metallic pipes, they can only be fixed by using iron chains, iron clamps, screws or other binding methods. This fixing method is very cumbersome and usually requires at least two people to cooperate and consumes a lot of manpower. Utility Model Content
