TC-MW type bull's eye two-color water level gauge is a direct reading instrument used to monitor the water level of subcritical and supercritical boilers and pressure vessels. This type of two-color water level gauge has a self-flushing structure in the body, which can prevent the observation hole from hanging on, and improve the display effect and the service life of the window. This type of water level gauge has the function of steam tracing, which uses the saturated steam in the steam drum to trace the water level gauge to reduce the water level difference caused by the temperature difference between the steam drum and the water level gauge, so that the water level measurement is more accurate. TC-MW type bull's eye two-color water level gauge has explosion-proof function and is suitable for the application of explosion-proof sites in the petrochemical industry and other industries.

TC-MW type bull's eye double-color water level gauge window sealing structure is divided into winding type and disc spring type. The disc spring type sealing structure is specially designed for the working conditions of frequent starting and stopping of cracking furnaces in the petrochemical industry. Airtightness ensures safe, reliable and stable operation of the device.
