Tempered Borosilicate Reflex Level Gauges DIN7081

What is Reflex Level Gauges? Made of tempered borosilicate, this type of reflex level glass for gauges is used in various applications requiring both chemical resistance and a low thermal expansion coefficient. The glass is manufactured in compliance with the international DIN7081 standard, ensuring quality and reliability. To standardize this type of sight glass across industries, the German regulatory institute, DIN, established standardized parameters for its production. Efficient Reflex Level Gauges - Features The main features of this standard include dimensional parameters, pressure resistance, chemical composition, characteristics of the reflective prisms, tolerance parameters for parallelism, and required acceptance tests. Since the glass has reflective prisms, the light spectrum reflects in such a way that where there is liquid, the glass appears opaque, and where there is no liquid, it appears bright. These glasses are mainly used in the petrochemical industry, oil industry, and general-purpose applications. Additionally, because the glass features reflective prisms, the light spectrum reflects so that areas with liquid appear completely opaque, while areas without liquid appear bright. These are primarily utilized in the petrochemical industry, refineries, and general-purpose applications.
