See Boiler Water Level at Any Angle, Any Distance — Patent #7,047,806B2
The Simpliport® 180 System is a complete boiler water level gage solution consisting of a stainless-steel gage body, LED illuminator assembly, and wide-angle optic viewing hood assembly. There are no service parts associated with the viewing hood assembly.
Manufactured and installed to meet ASME Boiler Code Section I requirements, the Simpliport 180 is the only high-pressure gage with a repairable body — providing significant economic advantage over competitors. Over 15,000 units are in service worldwide.
The Simpliport operates on light refraction principles. Light does not refract through water on the same line that light reflects through steam. By calculated placement of a light source and gage glass, the gage provides an unmistakable two-color display:
Green Ports = Water
Ports at and below the water line display green — indicating liquid water present in the boiler.
Red Ports = Steam
Ports above the water line display red — indicating steam space above the water level.
Nipple Connections — Standard, ANSI Flanges, or Male/Female Socket Welds
The P4000 Series features a spiral wound sealing gasket, unique inner support ring, and cushion pad — eliminating the hot-torque step required on past models. The gage is ready-to-use upon installation. Gage bodies are manufactured from Type 304 stainless steel for extreme strength, light weight, and durability. The six-port Model P4006 (12-5/8 inch visibility) weighs only 14 lbs.
Direct reading to 3000 PSI (206 Bar)
Spiral wound sealing gaskets
No hot-torquing required
Highest quality (V1), thickest (30 mil) mica shields
Over 15,000 units in service worldwide
Repairable body — significant economic advantage
Visibility 10-1/4 in (260 mm) to 71-5/8 in (1819 mm)
Tightly spaced ports for maximum reading accuracy
