Threaded Double Window Indicator – Stainless Steel

Stainless Steel Double Window Flow Indicators are devices used in various industrial applications to monitor the flow of liquids in pipelines. Threaded Double Window Indicator They feature a cylindrical body made of stainless steel, a durable and corrosion-resistant material. The key characteristic of these indicators is the presence of two windows, typically made of tempered glass or acrylic, positioned opposite each other. These windows provide a clear view of the fluid passing through the indicator. Stainless Steel Flow Indicators – Applications: These double-window threaded flow indicators are particularly useful in food and beverage processing, pharmaceutical, chemical, and other industries where direct observation of tank contents is essential for process monitoring and control.

After correctly welding the cover flange (2) to the vessel wall, assemble the gasket (3), the sight glass (4), the gasket (3), and the cover flange (2) in that order. Tighten the bolts (1) according to the torque values indicated in the technical information table (always tighten bolts in diametrically opposite sets). Threaded Double Window Indicator - Benefits Enhanced Quality Control: Enables direct visual inspection, helping to prevent quality issues before they escalate. Operational Safety: Allows observation without opening the tank, minimizing exposure to hazardous substances. Ease of Maintenance: Weldable and robust design simplifies installation and maintenance of the sight glass.
