Applications of Oil Liquid Level Indicator Sight Glass Gauge Glass Tube Level Gauge

1. General Machinery Lubricating Oil Tanks

Gearboxes, hydraulic stations, rolling mill thin oil stations, air compressor oil tanks. Directly observe lubricant volume to prevent oil shortage and equipment abrasion. Brass valve small glass tube oil gauges are widely used for low-cost routine monitoring.

2. Generator & Diesel Engine Fuel Tanks

Diesel generator sets, agricultural machinery fuel tanks, vehicle auxiliary oil boxes. Check residual fuel visually; simple structure, easy on-site inspection without power supply.

3. Boiler & Thermal Oil Heating Systems

Heat conduction oil expansion tanks, fuel oil storage auxiliary tanks. Monitor oil level to avoid dry burning and oil overflow faults.

4. Light Industry & Factory Central Oil Depots

Small diesel, lubricating oil storage barrels and transfer tanks. Low pressure normal temperature oil medium, economical glass tube oil gauges meet daily patrol observation demands.

5. Hydraulic Equipment & Injection Molding Machines

Injection molding, stamping machine hydraulic oil tanks. Quickly judge oil shortage or oil leakage faults during equipment maintenance.

6. Construction & Agricultural Machinery Equipment

Excavator auxiliary oil tanks, irrigation diesel power machine oil boxes, breeding heating fuel tanks. Outdoor low-pressure working condition, easy to replace broken glass tubes on site.

Core Matching Advantages

Fully mechanical, no electricity, reliable for power-off equipment.
Low price, simple installation, spare parts cheap and easy to obtain.
Clear transparent glass, direct real-time observation of oil height and oil quality.
Compact size, fits narrow installation space on small oil tanks.

Limitations

Only for low-pressure normal-temperature light oil media; not applicable for high-temperature, high-pressure or corrosive oil.

Common Failures & Solutions for Glass Tube Oil Level Gauge

Oil leakage at valve jointsCause: Aging, cracked or uneven gaskets; loose bolts/cocks.

Solution: Replace intact gaskets; tighten fasteners evenly diagonally.
Blurred, foggy glass tube, hard to read oil levelCause: Oil dirt, carbon deposit and scale attached on tube inner wall.

Solution: Close cocks, drain oil, remove and clean the glass tube thoroughly.
Glass tube brokenCause: Impact, uneven bolt tightening, thermal shock.

Solution: Shut off valves to isolate the gauge; replace new glass tube and install protective cover.
Cock valve stuck, cannot open/close smoothlyCause: Oil sludge, impurities stuck inside valve cavity.

Solution: Discharge residual oil, rinse valve body; replace the cock if severely jammed.
False oil level, slow liquid level responseCause: Air trapped inside the glass tube; blocked connecting pipeline.

Solution: Open drain cock to exhaust air; clear blockages in connecting pipes.
Self-sealing steel ball fails to block oil after tube breakageCause: Ball stuck by dirt, can not slide freely.

Solution: Disassemble and clean the cock, ensure steel ball moves flexibly.
