1、Superior Performance: The liquid level gauge has a reasonable structure. Novel appearance, clear display of liquid level and liquid temperature, with connectors, and superior assembly performance. Liquid level meter has the advantages of superior performance, firmness, crack resistance, shock resistance, etc. 2、Intuitive Liquid Level: Suitable for the measurement of the liquid level and interface of the liquid medium in the container, transparent glass medium,intuitive and eye catching. 3、Excellent Airtightness: The level gauge is isolated from the measured medium, with good airtightness, high reliability and safe use. 4、Optimized Design: A self sealing valve is added to the liquid level gauge. When replacing or repairing the liquid level gauge, just unscrew the installation screws, the self sealing valve will close by itself, cut off the oil circuit, and remove the oil without releasing the oil in the fuel tank. Level gauge is very convenient to use and maintain. 5、Wide Applications: Oil liquid level gauge meter is used for liquid level measurement and control in the production process of machinery, electric power, petroleum, chemical industry, metallurgy, environmental protection, shipbuilding, construction, food, catering and other industries.
