# KLINGER > Borosilicate Gauge & Sight Glasses ## Pages - [Installation instruction for gauge glasses](https://klinger.co.in/installation-instruction-for-gauge-glasses/): Basically, gauge glasses must be installed in a clean and plane holder between two special KLINGER gaskets. Make sure that the contact surfaces of the… - [Why do we need to replace gauge glasses?](https://klinger.co.in/why-do-we-need-to-replace-gauge-glasses/): Gauge glasses in liquid level gauges on steam boilers are exposed to very high mechanical and chemical stresses. The interface between steam and water is… - [Operating principle of bi-colour type Liquid Level Gauges](https://klinger.co.in/operating-principle-of-bi-colour-type-liquid-level-gauges/): The bi-colour level gauge is in principle a transparent gauge in which the centre-piece has a wedge-shaped section. This design makes bi-colour indication possible. Two… - [Operating principle of Transparent type Liquid Level Gauges](https://klinger.co.in/operating-principle-of-transparent-type-liquid-level-gauges/): The liquid column is contained between the two gauge-glasses. When necessary an illuminator is mounted on rear-side of the gauge; its light rays are deflected… - [Operating principle of Reflex type Liquid Level Gauges](https://klinger.co.in/operating-principle-of-reflex-type-liquid-level-gauges/): The principle of the reflex glass is based on the difference in the refractive indices of liquid and gas or, in particular, of water and… - [Choosing the right liquid level gauge](https://klinger.co.in/choosing-the-right-liquid-level-gauge/): The determining factors for choosing a gauge are the medium and the pressure and temperature range within which the gauge is to be used. It… - [Transparent gauge glasses](https://klinger.co.in/transparent-gauge-glasses/): made of borosilicate glass “extra-hard”, long types KLINGER transparent glasses are manufactured from “extra-hard” borosilicate glass. The surfaces on both sides are finely ground and… - [Reflex gauge glasses](https://klinger.co.in/reflex-gauge-glasses/): made of borosilicate glass “extra-hard”, long types The side facing the medium chamber is provided with moulded grooves set at 90° angles. The moulding process… - [Borosilicate Gauge & Sight Glasses](https://klinger.co.in/): Borosilicate Gauge & Sight Glasses The gauge glass is the most important component of the liquid level gauge. The quality of a sight (gauge) glass… - [Blog](https://klinger.co.in/blog/) ## Optional - [Agent (MCP protocol)](websites-agents.hostinger.com/klinger.co.in/mcp) [comment]: # (Generated by Hostinger Tools Plugin)
