Threaded Flow Indicators

Flow indicators with threads for pipe connections. These models offer view inside any pipeline through back and front windows. Flapper style indicators are recommended for monitoring either horizontal or vertical lines with upward flow. Rotators style indicators are best for quick visual assessment if there is any flow in a pipeline. The rotator wheel has high contact against fluids of any color. Drip tube indicators are for vertical lines with downward flow direction having low or intermittent flow rates, such as distillation process. Plain view indicators can be installed in any position to observe flow in any direction, or to detect the presence or absence of solutions.

Plain Style NPT Threaded Flow Indicators, Carbon Steel or 316 Stainless Housings

Plain Style NPT Threaded Flow Indicators, Carbon Steel or 316 Stainless Housings
Visual flow indicators with NPT threaded female ports. Thread form complies with the ASME B1.20.1 standard, in carbon steel or 316 stainless housings. Designed with front and back windows for backlighting making it easy to see flow variations inside any pipeline, even when used with dark liquids. There are no inserts between the two windows, these flow indicators are best suited for - non-homogeneous fluids to see bubbles, color changes and any indication of flow variations within the fluid.

These flow indicators are installed in-line of the pipeline between two threaded pipe ends. This model offers pipeline view through toughened borosilicate glass windows internally sealed to the metal housing with flat gaskets. May be installed in any position to observe flow in any direction. These indicators are usually employed to detect either the presence or absence of solutions, or to observe fluids for turbulence, color or clarity.

Rotator NPT Threaded Flow Indicators, Carbon Steel or 316 Stainless Housings

Rotator NPT Threaded Flow Indicators, Carbon Steel or 316 Stainless Housings
Visual flow indicators with NPT threaded female ports and a rotator wheel in the flow path. Thread form complies with the ASME B1.20.1 standard. Designed with front and back windows for backlighting making it easy to see flow variations inside any pipeline, even when used with dark liquids.

There is a rotating wheel between the two windows enabling to quickly see if there is any flow going through the pipe. The visibility of the rotor motion makes this style particularly well suited for monitoring clear, translucent or solutions with dark colors, as the rotator is clearly distinguished from the background of the fluid.
