Aluminum Liquid Level Gages with Card Thermometers are for any application requiring visual indication of both liquid level and liquid temperature.  These gages can be used to view liquid levels and temperatures in hydraulic reservoirs, gearboxes, bearing housings, crankcases, transformers and machinery oil reservoirs.  The red fluid indicator on the card thermometer allows temperature to be easily viewed.  

This sturdy gage is made of corrosion and rust resistant milled aluminum.  The end pieces are permanently secured through a staking process.  The unit tolerates up to 175 PSI and 225° F.  The liquid viewing sight is glass.  Leak-proof construction is achieved with Buna-N seals.  Temperature is indicated with red fluid in both degrees Fahrenheit and Celsius on the 8 1/2” tall aluminum and glass thermometer.  It displays -20° to 220° F and -25° to 100° C. 

Fluid enters through the cross hole in the hollow lower bolt.  The gage is vented into the tank through 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) aluminum bolts with 1/2" male NPT adapters.

For additional mounting options, seals and fractional inch centerline distances, reference the “Other Options” document located on this page.
