Double Window Threaded Steel AC AI304-AI316 Catalog

DOUGLASS flow sight glasses, manufactured in steel, allow for fluid visibility within the pipeline. They can be manufactured with a threaded NPT connection at 150 PSI. Depending on the type of fluid, they can have different viewing options:

  • · Free passage type, where the flow is easily visible, and anomalies are inspected.
  • · Rotor type, where the fluid is translucent, and the inspection is focused on flow presence.
  • · Fin type, which serves as an alternative to the rotor and measures flow intensity.
  • · Drip type, designed for gases.

These indicators are forged as a single piece, ensuring excellent resistance to pressure and harsh conditions. They are manufactured for connections of 1″, 1-1/2″, 2″, and 3″, and the choice of seals and glass materials will be recommended based on operating conditions.
