Tubular Industrial Liquid Level Gauge

Our Tubular Level Gauges use Borosilicate (Pyrex) tubing to view liquid levels. The tubing is designed to be thick-walled and durable, providing a clear view of the liquid levels inside your tank or process. All valves use a stuffing box configuration with a compressed elastomer ring to seal and feature ball check shutoff to prevent loss of vessel contents in case of glass failure. The carbon steel configuration is the most affordable option available, while 316 stainless steel provides excellent corrosion resistance for applications that might attack carbon steel. Regardless of your choice, our valves are designed for easy replacement of glass tubes.

Technical information can be easily downloaded in PDF format from the menus on the right. Please note that operating pressure and temperatures are subject to the limitations of the tubular gauge glass and washer composition. Our valve bodies are rated for 500 PSIG at 450F, but the actual pressure limitations are determined by the gage glass.

The following pressure values are for industry standard high pressure gage glass use (steam values are for reference only - for steam service, choose stainless steel valves). We can also provide extra long gauges, as well as armored level gauges according to your needs. We have expert engineers standing by for consultation and quotes, so please contact us.
