Description

Technical Field

[0001] The utility model relates to the technical field of liquid level meters, in particular to a radar liquid level meter with high measurement accuracy. Background Art

[0002] The radar level meter is a microwave level meter that works by transmitting energy waves through a device that can transmit energy waves. 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.

[0003] For example, a radar level meter with high measurement accuracy with authorization announcement number CN220322489U includes a shell, a control terminal and a level meter body. A dehumidification component is arranged in the shell, and the dehumidification component includes a heat insulation sleeve. An air inlet groove and an air outlet groove are respectively opened in the shell. Although the above document can effectively prevent water vapor from entering the radar level meter to release heat and condense to affect the measurement accuracy; however, when the radar level meter is in use, during the process of measuring the liquid position, since the bottom of the radar level meter is always in an open state, when the radar level meter is not in use, dust in the outside air passes through The opening at the bottom of the radar level meter may cause the inside of the radar level meter to fall, resulting in dust accumulation inside the radar level meter. Errors are likely to occur during measurement, thereby reducing the measurement accuracy of the radar level meter. At the same time, when the radar level meter measures the liquid position, the radar level meter is installed at the specified position through the cooperation of the flange and bolts. During installation, the staff needs to use external tools to turn the bolts to install the radar level meter. Without external tools, the installation cannot be performed, thereby reducing the convenience of installation of the radar level meter. Utility Model Content

Then the staff rotates the fixing devices 7 on both sides in the opposite direction, removes the circular plate 6, and starts the radar level meter body 3. The radar level meter body 3 emits radar waves into the container. After the radar waves contact the liquid in the container, they are reflected back into the radar level meter body 3 to measure the position of the liquid level inside the container.
