Reliance Simpliport® 180 Bi-Color Ported Water Gage Glasses & LED Illumination (Clark-Reliance)

The Reliance Simpliport® 180 Bi-Color Ported Water Gage Glasses & LED Illumination (Clark-Reliance) provides direct-reading boiler water level indication with bright red and green visibility. The system helps operators see steam and water level from any position within 180° of the viewing hood, reducing time spent near the boiler while supporting clear, code-required visual confirmation.

This Simpliport water gage system combines a stainless-steel gage body, LED illuminator assembly, and wide-angle optic viewing hood. Red ports indicate steam, while green ports indicate water level. The LED illuminator uses high-intensity, long-life red and green LEDs, which remove the need for traditional red and green glass colour strips.

The Simpliport 180 system supports ordinary, non-classified locations and hazardous, classified locations when configured with the appropriate illuminator and power supply. It also supports indoor and outdoor use, making it a strong choice for Canadian boiler rooms, power plants, industrial facilities, and retrofit applications.

Westech Industrial offers the Reliance Simpliport 180 Canada-wide, along with product selection support, service capabilities, and custom fabrication for integrated boiler instrumentation solutions, panels, and project-specific requirements.

Description

180° Wide-Angle Boiler Level Visibility

The Simpliport water gage gives operators a clear view of boiler water level from almost any angle. Wherever personnel stand within 180° of the wide-angle hood, they can see the bright red or green indication. As a result, teams can check level from a safer and more practical viewing position.

The wide-angle optic viewing hood improves visibility from different distances as well. In many applications, it also removes the need for mirrors. This helps simplify the boiler area and gives operators a more direct view of the gage.

Bright LED Illumination with Red and Green Indication

The Simpliport LED illuminator uses high-intensity red and green LEDs to show steam and water level. Red indicates steam above the water line, while green indicates water in the boiler. This bi-colour indication helps operators interpret boiler level quickly.

In addition, the LED design removes traditional red and green glass colour strips. The LEDs generate no heat and use low power, which helps reduce maintenance concerns around the illuminator. Depending on the configuration, LED service life can reach up to 10 years. Therefore, it offers a longer-lasting option than older incandescent or halogen lamp designs.

Built for High-Pressure Boiler Service

The Simpliport water gage provides direct-reading boiler level indication up to 3000 PSI or 206 Bar. It uses the proven principles of light refraction to show the difference between steam and water. This gives facilities a dependable visual indication method for critical boiler applications.

The 4000 Series gage body uses spiral wound sealing gaskets with an inner support ring and cushion pad. This design removes the hot-torque step required on earlier models. Therefore, the gage arrives ready for use after installation.

Repairable Stainless-Steel Construction

Clark-Reliance manufactures Simpliport gage bodies from Type 304 stainless steel. This construction gives the gage strength while keeping it relatively lightweight. The repairable body also helps operators reduce lifecycle costs compared with non-repairable high-pressure designs.

The gage includes high-quality V1, 30 mil mica shields. It also uses “all-around” spring support for glass disc modules. This support creates more uniform loading, which helps prolong glass life in demanding boiler conditions.

Retrofit-Friendly Viewing Hood

The wide-angle viewing hood can improve visibility on existing Simpliport gages. It can provide clearer readings from dirty or contaminated gages, depending on site conditions. Because of this, the Simpliport water gage works well for retrofit projects where operators need better visibility from existing equipment.

The hood also installs easily with thumb screws. Teams can remove or install the illuminator hood without special tools. An optional sun shield supports outdoor visibility and adds only 5 inches, or 127 mm, to the viewing hood length.

Ordinary and Hazardous Location Options

The Simpliport water gage supports ordinary, non-classified locations. It also supports hazardous classified locations with NEC Class I, Division 2 illuminator options. Hazardous location models can use local or remote power supplies, which gives installers more flexibility.

For remote hazardous configurations, the power supply can sit up to 1000 feet, or 303 metres, from the illuminator. This helps facilities place electrical components where they best fit the site layout.

Applications

The Reliance Simpliport 180 supports boiler water level monitoring where operators need direct, clear, and dependable visual indication. It works well in facilities that need high-pressure boiler gage glasses, improved operator visibility, and indoor or outdoor installation flexibility.

  • High-pressure steam boilers
  • Boiler drums and steam drum level indication
  • Power generation facilities
