After adopting the above scheme, when in use, the liquid level transmitter body 1 can select different installation methods for different application scenarios. When short-distance transmission is adopted, two sets of clamping mechanisms 4 can be used to assemble and connect the fixed flange 2 and the liquid level transmitter body 1, and the liquid level transmitter body 1 can be fixed to the pipeline or liquid tank through the fixed flange 2.
