GrandMfg® Tubular Oil Level Indicators

Monitor hydraulic fluid or oil level in gear boxes, crank cases, and other reservoirs.

These indicators mount from the outside of your tank. The gauge shield, which protects the indicator from impact, rotates 360° for optimal viewing.

Use these indicators in nonpressure applications.

All have a vent to prevent pressure from building up and causing an inaccurate level to display. You can also unthread the vent and replace it with your own vent, plug, fitting or sensor.

Indicators with a swivel fitting have a two-piece construction, so they can be quickly disconnected.

Indicators with a drain allow you to sample hydraulic fluid from the reservoir.
