[0002] Reactors are commonly used equipment in the chemical industry. In order to monitor the liquid level in the reactor, a liquid level display structure is generally set up. The principle of liquid level display is generally the principle of communicating vessels. However, the current liquid level display can only display the liquid level, and additional interfaces are required for pressure and sampling, which increases the difficulty of operation and production of the equipment. Therefore, we designed a reactor liquid level display structure. Utility Model Content
