Whitepaper Sight Flow Indicators and Their Applications in Process Systems
The ability to see what is happening inside a pipe can be invaluable to process operators. Despite technological advances, no sensor can equal the human eye which has more than 94 million photo receptors.
Process observation equipment falls into two major categories: sight glasses, also called sight glass windows, which are used on process vessels, and sight flow indicators, which are used in process pipelines. This white paper covers the latter. (For information on sight glass windows, see our Chemical and Pharmaceutical Sight Glass Application Handbook.)
A sight flow indicator is a device installed in a pipe to provide a visual means of verifying liquid flow for direction and approximate rate. Simple and low-cost, it also allows operators to observe the color and clarity of process fluids through a window. -
