[0002] Liquid level transmitters are widely used in industrial production, environmental monitoring, water treatment, agriculture, energy, transportation and other fields. In industrial production, they monitor the liquid level in storage tanks, reactors and other equipment in real time to ensure smooth production. During assembly, the transmitter host needs to be placed outside the container, and the guide rod for the float is set inside the container. The guide rod and the transmitter host must be installed between the container shell.

[0003] When the guide rod of the existing liquid level transmitter is assembled with the liquid container equipment, it is necessary to open multiple holes for the flange bolt installation on the shell of the container or equipment, which makes the installation of the liquid level transmitter difficult and greatly reduces the sealing of the container. Therefore, a guide rod mechanism of the liquid level transmitter is proposed to provide a set of transmitters that can quickly guide rod mechanisms for containers or equipment that require liquid level detection. It only needs to open holes for the guide rod on the container or equipment and pass them through, so that the transmitter host can be quickly installed on the container or equipment, greatly improving the convenience of use and installation efficiency of the liquid level transmitter.
