### PART I: Basics of Specifying the Correct Sight Flow Indicator

I’ve been working in the process industry for a long time, and every now and then I come across a gem of information and try to pass it on. Here I’ll try to tell you a bit about how to select the correct sight flow indicator.

### Can You Trust Flowmeter Accuracy Specifications?

The majority of today’s flow technologies are volumetric, meaning the devices measure velocity and calculate volume by using a pipe’s inner cross-sectional area (Velocity (feet/second) x Area (Ft2) = Volumetric flow rate (ft3/s)). In every case without exception, the higher the velocity the more accurate the device’s measurements will be.
