Item # B3950-22700BN4W, Broad Face Nylon Liquid Level Gage with Dial Thermometer, 27" Centerline, 3/4" Male NPT Adapters

Broad Face Nylon Liquid Level Gages with Dial Thermometers feature a large dial thermometer and wide rectangular sight, allowing liquid level, clarity and temperature to be easily viewed from a distance.  These gages can be used on machinery oil reservoirs, tanks, gearboxes, bearing housings, crankcases, hydraulic equipment, transformers and other applications requiring visual indication of both liquid level and liquid temperature.


This Liquid Level Gage has a clear, durable nylon sight that is rectangular in shape.  The front viewing area is 1 3/4” wide.  A 1/8” wide red line on the back of the sight enhances liquid level visibility.  Easy-to-read “High” and “Low” level markings provide additional visual cues.  Two aluminum tie rods run through the center of the sight connecting the aluminum end blocks.  Leak-proof construction is achieved with Buna-N seals.  Temperature is indicated in both degrees Fahrenheit and Celsius on the 2 3/64” diameter stainless steel thermometer.  It displays 0 ° F (-20° C) to 250° F (120° C).  The unit tolerates up to 50 PSI and 205° 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 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) aluminum bolts with 3/4" male NPT adapters.


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