Frequently Asked Questions
What is a reflex flat gauge glass?
A reflex flat gauge glass is a type of sight glass used in boiler water level gauges. The reflex prism creates a sharp contrast between water and steam, making level indication clear and easy to read in marine applications.
How do I choose the correct size?
Measure the length, width, and thickness of your existing gauge glass, or refer to your gauge assembly's specifications. Our standard sizes include various lengths; ensure a proper fit for a leak-tight seal.
What is the maximum operating temperature and pressure?
These reflex flat gauge glasses are designed to withstand temperatures up to 250°C and pressures up to 30 bar, making them suitable for typical marine boiler systems.
Are these gauge glasses compatible with all marine boilers?
They are manufactured to standard marine and industrial specifications (IMPA 813201) and are designed to fit most common reflex gauge assemblies. However, always verify dimensions and ratings before installation.
