Feature: 1. ESSENTIAL PART: This level gauge is an essential accessory for oil tank, lubricating device, cooling box and gear transmission box to display liquid level and fluid. 2. MULTI PURPOSE: This oil liquid level meter is applicable to mineral oil, water in oil, water glycol and other working media. 3. HIGH PERFORMANCE: The liquid level gauge has reasonable structure, novel appearance, clear display of liquid level and temperature, superior assembly performance, firmness, crack and shock resistance. 4. SELF SEALING: Liquid level gauge is equipped with a self sealing valve. When replacing or repairing, just unscrew the mounting screw, and the self sealing valve will automatically close and cut off the oil circuit. 5. WIDE USAGE: The liquid level gauge can be used in the shipbuilding industry, chemical industry, automobile manufacturing, engineering machinery, metallurgy industry, mechanical equipment. Specification: Item Type: Oil Liquid Level Gauge Material: Alloy, Glass Model: YWZ 80T Temperature: 20 to 80 Pressure: 0.1 to 0.15MPa. Package List: 1 x Oil Liquid Level Gauge Note: Installation Method:1. According to the specification and size of the selected level gauge, two mounting holes shall be machined on the side plate of the oil tank as required.2. For example, when the wall thickness of the oil tank is less than or equal to 10mm, the two installation holes are 11mm.3. If the wall thickness of the oil tank is greater than 10mm, the two mounting screw holes are M10.4. If self sealing valve is selected, the two installation holes are D19mm. The machining tolerance of the center distance between the two mounting holes on the oil tank is required to be 0.2mm.Note:1. The plane of the mounting hole should be straight to prevent oil leakage after installation.2. When installing the level gauge screw, the tightening force should be moderate, sealing properly without oil leakage and avoid damaging the level gauge. Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures. Please allow slight dimension difference due to different manual measurement.
