Problems solved by technology

Due to the high viscosity of the commonly used liquid couplant, even if it is wiped in time after the test is completed, some parts will remain on the surface of the equipment, resulting in damage to the appearance of the container, which is not allowed in quite a few fields
In addition, viscous liquid couplants can bond with atmospheric dust to form a scale, rendering the site no longer detectable
And when the equipment is located higher than the ground or close to the live parts, if it is necessary to apply a viscous couplant for each detection and then wipe it off, the operation process is too cumbersome and has a certain degree of danger. The viscous liquid couplant not applicable

Abstract

The invention provides a solid coupling agent for a portable ultrasonic liquid level detector. The solid coupling agent is mainly composed of base glue and a filler. The solid coupling agent has goodelasticity, and can be obviously deformed under the action of an external pressure; and an air gap between a piezoelectric ultrasonic probe and tested equipment can be eliminated, so that the purposeof eliminating air layer blockage is achieved.

Description

technical field [0001] The invention belongs to the technical field of coupling agents for ultrasonic liquid level instruments, in particular to a solid coupling agent for portable ultrasonic liquid level detectors. Background technique [0002] Ultrasonic liquid level gauge, as a typical non-contact measuring instrument, is widely used in liquid level measurement occasions in many fields such as industry and national defense. The principle is that ultrasonic waves have a great penetrating ability to liquids and solids. When encountering an interface composed of two different media, significant reflections will occur, forming reflected echoes, and thus calculating the distance from the liquid surface. Since the ultrasonic wave can hardly pass through the air-solid (liquid) interface, there must be no air medium between the ultrasonic probe and the object to be measured, otherwise the formed air-solid (liquid) interface will block the propagation of the ultrasonic wave and ca...
