Sight Flow Indicators

A sight flow indicators is a device installed into a pipe to provide a visual of verifying liquid flow for direction and accurate flow rate. Sight flow indicators allow operators to observe the color and clarity of liquids through a window. A sight flow indicator is a body with one or more viewing windows, usually with gaskets, and a way to mount the indicator to the pipeline, such as flanged, threaded, or sanitary clamp connections. Sight flow indicators are available to fit standard pipe sizes ranging from 1/4-inch to 16-inches and carry ANSI pressure ratings. Sight flow indicators allow direct observation that do not give a false reading, lose power, or unable to read. Sight flow indicators may be applied to almost every phase of movement, whether it is liquid, gas or powder. Operators of the Sight flow indicator can see the approximate rate of flow, direction of flow, and condition without interrupting process flow. To find out more about the John C. Ernst sight flow indicators, contact one of our specialists today.
