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 gage is specially configured.


This sturdy gage is constructed with a 304 stainless steel body and internal cap. The external cap and mounting bolts are 303 stainless steel.  The glass sight has silk-screened level-markings to clearly indicate fluid level.  The sight is protected by 304 stainless steel on three sides.  Leak-proof construction is achieved with Viton seals.  The unit tolerates up to 125 PSI and 225° F. 


A standard configured gage has the viewing area facing forward, while this gage has the glass sight oriented at 90° angle to the tank.  The mounting bolts are reversible, allowing the gage to be installed with the sight oriented to the left or right side. 


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 8” centerline measurement.  This gage is mounted from the front of the tank with (2) 3/4”-16 stainless steel bolts.  The bolts should be torqued to 90 in-lbs.
