Sight Flow Indicators

Standard inline sight flow indicators for general process monitoring. Available with flapper, drip tube, or rotary flow indicators. Bodies in bronze, carbon steel, or 316 stainless steel with borosilicate glass windows. Threaded or flanged end connections.

Compact inline sight flow indicators designed for space-constrained installations. Suitable for monitoring flow direction and approximate flow rate in standard process piping. Available in multiple sizes and end connection styles.

Built for demanding high-pressure service with extra heavy wall cylinders. Suitable for steam, hydraulic, and high-pressure chemical applications. Available with flapper, drip tube, or rotary indicators and multiple body material options.

Cylindrical glass body provides a 360° unobstructed view of the process stream for maximum visibility. Constructed from carbon steel or stainless steel with flanged or threaded ends. For high-pressure applications, extra heavy wall cylinders are available.

All wetted parts lined with PTFE (except the borosilicate glass) making them inert to corrosive fluids including chlorides, sulfates, bleach solutions, solvents, acids, and phenols. Ideal for chemical processing and corrosive service applications.
