[0002] Guided wave radar level meter is a liquid level measuring instrument in the chemical industry. It is a radar level meter based on the principle of time domain reflection. The electromagnetic pulse of the radar level meter propagates along the steel cable or probe at the speed of light. When encountering the surface of the medium to be measured, part of the pulse of the radar level meter is reflected to form an echo and returns to the pulse transmitter along the same path. The distance between the transmitter and the surface of the medium to be measured is proportional to the propagation time of the pulse between them, and the liquid level height is calculated.

When the two plug blocks 6 move in the opposite direction, the other end squeezes the two torsion springs 8. When the protective shell 9 drives the positioning rod 12 to move downward and contact the top of the mounting plate 3, the plug block 6 is released, and the reaction force of the torsion spring 8 drives one end of the two plug blocks 6 to move toward each other, so that the protective shell 9 can be installed and positioned. The protective shell 9 can be used to protect the outside of the liquid level meter body 1 from rain and dust, thereby improving its service life. When the staff needs to inspect the liquid level meter body 1, the protective shell 9 is disassembled and the two shift blocks 203 are shifted toward each other. When the two shift blocks 203 move toward each other, they squeeze the two springs 205 and drive the two plug rods 204 to move toward each other. After the two plug rods 204 move toward each other and leave the inner cavity of the jack 10, the positioning plate 201 and the liquid level meter body 1 can be taken out from the inner cavity of the mounting plate 3, thereby improving the maintenance efficiency of the staff.
