Levelux Liquid Level Gages provide illumination of the liquid level. A motion activated LED light not only enhances visibility of the fluid level, but also draws attention to the gage. It helps operators or maintenance individuals monitor the contents and avoid depleting the oil. Levelux is particularly useful in dimly lit areas or where the line of sight is partially obstructed.Standard Steel Liquid Level Gages can be used to view liquid levels in hydraulic reservoirs, tanks, large steel mill pumps, gearboxes, bearing housings, crankcases, transformers and machinery oil reservoirs. Their use can be extended to any industrial liquid level viewing application.","This sturdy gage is made of plated steel. The glass sight is protected by steel on three sides. A red line on a white background enhances liquid level visibility. Leak-proof construction is achieved with Buna-N seals. The unit tolerates up to 125 PSI and 185° F.","Fluid enters through the cross hole in the hollow lower bolt. The gage is vented into the tank through the cross hole in the top bolt. The length between the center of the two bolts is referred to as the center line. The distance between the center of the tank holes must be within 1\/32 of the center line measurement. This gage is mounted from the front of the tank with (2) 1\/2-20 plated steel bolts. The bolts should be torqued to 90 in-lbs.","To view NPT Adapters for this steel liquid level gage, click here.
