The energy waves are reflected by obstacles, and a receiving device receives the reflected signal. It determines the level change by measuring the time difference of the energy wave movement process. The microwave signal is processed by an electronic device and finally converted into an electrical signal related to the level to work.

The filling mechanism includes a No. 1 ring plate, a No. 2 ring body, a sealing ring, an airbag, a storage tube, a movable rod and a limit head. Through the provided filling mechanism, the No. 2 ring body is upwardly inserted into the gap between the protective sleeve and the horn head, and the sealing ring makes the No. 2 ring body and the protective sleeve sealed, and the gas is introduced to expand the airbag, and the airbag and the side of the horn head are squeezed and contacted with each other to seal, fill the gap between the horn head and the protective sleeve, and prevent the volatile corrosive liquid and volatile gas from entering, corroding and damaging the horn head, so that the radar level meter is more suitable for use with chemical liquids.

[0004] However, during the implementation of the above technical solution, it was found that there were at least the following technical problems:

In addition, the flange needs to be fixed with multiple bolts during installation, which makes the installation more laborious. Therefore, the existing device has the problem of being troublesome to install and disassemble.

[0006] 2. The existing device uses a protective sleeve to strengthen the seal, but there are gaps on the outside of the protective sleeve that can allow toxic gases to seep out, so the existing device is still lacking in sealing. Utility Model Content
