Aluminum Liquid Level Gages can be used to view liquid levels in hydraulic reservoirs, gearboxes, bearing housings, crankcases, transformers and machinery oil reservoirs.  Their use can be extended to many industrial liquid level viewing applications.  This gage was designed to a customer’s specifications.


This sturdy liquid level gage is made of corrosion and rust resistant milled aluminum.  The glass viewing sight is protected by the aluminum body on three sides.  A clear polycarbonate shield spans the front of the gage to completely enclose and protect the glass sight.  Leak-proof construction is achieved with Viton seals.  A white background enhances liquid level visibility.  Silkscreened “F” and “L” labels indicate the full and low liquid levels, while the “Idle” label clarifies the safe liquid level range.


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 centerline.  The distance between the center of the tank holes must be within 1/32” of the centerline measurement. This gage is mounted from the front of the tank with (2) M12 X 1.5 plated steel bolts.  The mounting bolts should be torqued to 90 in-lbs.


This gage tolerates up to 150 PSI and 225° F.
