Tubular Level Gauge


Tubular Level Gauges are designed to view liquid levels using clear or red line Borosilicate (Pyrex) tubing. All valves use a stuffing box configuration to seal the glass tube, and have a ball check shutoff to prevent loss of vessel contents in case of glass failure. Operating pressure and temperatures are subject to the limitations of the tubular gauge glass and washer composition; consult with PresSure Products for gauge glass ratings.
