Flow sight glass type GD200

Flow sight glass for demanding applications

Do you want to know what is flowing through your pipe? The GD200 flow sight glass makes it possible – in a clear and precise way. The sight glass is designed to meet the highest demands and can be used for oil, water, steam, chemicals, acids or bases. Manufactured in accordance with DIN 3237, this sight glass is temperature-resistant up to 280 °C thanks to borosilicate glass as per DIN 7080. Alternatively, it is also available with soda-lime glass – depending on the operating temperature and chemical resistance. Additionally, it comes with graphite seals that remain tight even at higher temperatures.

The GD200 sight glass is available in nominal sizes DN15-DN250, with standard flanges according to DIN PN16, PN25 or PN40. In addition to that, ANSI/ASME Class 150/300 is also available upon request. We can offer these flow sight glasses with bodies made of stainless steel (1.4408/Cf8M), cast steel (1.0619/GS-C25) and gray cast iron (GG25/EN-GJL-250), making them suitable for a wide range of gaseous/liquid media and operating conditions in industry and pipelines.

When it comes to tough applications in the pipelines and industries, the Fergo sight glass type GD200 offers the ultimate performance.
