Oil Level Indicator
Product Description
The Acrylic Bolt-On Oil Level Indicator is a compact mechanical device designed for direct visual monitoring of oil inside tanks and equipment. Its transparent acrylic body forms a vertical viewing channel, allowing operators to check the oil level quickly without opening the tank or using electrical sensors.
The indicator is mounted vertically to the tank wall using upper and lower bolts. Oil enters the viewing channel through the lower connection and rises to the same level as the oil inside the tank. The upper connection balances the pressure, enabling the displayed level to follow changes inside the tank.
The transparent PMMA body provides clear level visibility and is suitable for many common oils and compatible industrial fluids. Fluid compatibility should be confirmed for specific chemical or temperature conditions. Compared with a glass tube assembly, its one-piece structure is compact, lightweight, and less susceptible to accidental breakage. A marked level line, scale, or MIN/MAX indication can be added for easier inspection.

Application
This bolt-on oil level gauge is commonly used on:
- Distribution transformer tanks and conservators
- Hydraulic oil reservoirs
- Gearboxes and reduction units
- Lubrication systems
- Pumps, compressors, and industrial machinery
- Low-pressure oil storage equipment
