Our sight flow indicators can be made of stainless steel 1.4408, cast iron GS-C 25 or grey cast iron GG25. Whether you choose soda-lime-glass or borosilicate glass, the sight glass is then mounted between the mounting and the base flange using screws. The manufacturer also includes a graphite-seal. Sight-flow-indicators with flap, drip nozzle and rotor can be manufactured as thread sight glasses or flange sight glasses. Thread sight glasses come with internal threads from ¼“ - 2“ inch. Flange sight glasses come in nominal sizes ranging from DN15 to DN200. They are approved for up to PN16, from nominal size DN150 on only for PN10. Sight-flow-indicators withstand temperatures of up to +150°C. They can be mounted in any position, just keep the flow direction in mind. Buy your sight-flow-indicator directly from our online shop, or call our hotline if you need help choosing the right one. We would love to help you find the sight glass that fits your application and medium.
