Feature:1. [Self Sealing Valve] Water liquid level gauge adopts self sealing valve. When you remove the mounting screw, the self sealing valve will close by itself and cut off the oil line.2. [Basic Accessories] This level meter is the oil tank, lubrication device, cooling box and gear box to display the level and liquid necessary accessories, suitable for mineral oil, water a glycol and other working media.3. [Superior Performance] The level meter has reasonable structure, novel appearance, clear display of liquid level and liquid temperature, superior performance, sturdiness, crack proof, shock proof, and leak proof.4. [Simple Installation] The water liquid level meter is simple for installation and you just need to get the size of the mounting holes and you can easily install it.5. [Compact and Small] The compact size of this water level meter makes it easy to use and maintain, and very convenient.Specification:Item Type: Oil Liquid Level GaugeMaterial: Alloy, glassTemperature: 0-100Pressure: 0.1-0.15MP.Package List:1 x Oil Liquid Level GaugeNote:Installation method: 1. According to the specification size of the selected level meter, two installation holes are processed on the side plate of the tank as required. For example, if the wall thickness of the tank is less than or equal to 10mm, the second installation light hole is 11mm, if the wall thickness of the tank is more than 10mm, the second installation screw hole is M10.2. If you choose to use a selfsealing valve, the second installation light hole is 19mm, and the tolerance of the center distance of the two installation holes on the tank is 0.2mm, and the plane of the installation holes should be straight to prevent oil leakage after installation.3. When installing the level meter screws, the tightening force should be moderate to moderately seal without oil leakage to avoid damaging the level meter.
