Model 819 Tubular Level Gauge
Brand: John C. Ernst Co, IncThese Shielded Gauges provide you with safe viewing of fluid levels in your tank and a wide option of scales.
This design is simple to install and provides additional gauge glass protection. Glass protection is assured by a metal housing with a Lexan face which protects the glass tube.
The standard tube is 5/8" OD Clear Glass (borosilicate) and can be furnished as Redline Glass, Lexan, PVC, or Acrylic tubing.
Both gauges can be mounted with Model 324 Proximity Switches for High and Low Level Alarms.
Multiple sections of gauge glass are spliced together to meet the higher-pressure ratings up to 300 PSIG. Some applications can be rated to 400° F with reduced pressures.
Model 819 is designed with Integral Shutoff Valves with Automatic Ball Checks. The valves are offset for easy cleaning of the glass tubing through 1/4" vent or drain.
