Rotameter Introduction
Corrections for Gas Flow
Gas Flow from Air Flow:
Corrections for Liquid Flow

Corrections for Temperature and Pressure:
Correction for Temperature
(Note: for liquids the effect of pressure is negligible):
General Correction equations for approximating gas
or liquid flow from air or water flow readings.
The Variable-Area type flowmeter, or Rotameter, is one
of the most economical and reliable of flow
measurement instruments. In various configurations it
can be designed to withstand high pressures, corrosive
fluids, high temperatures, and is completely
independent of factors influencing electronic meters.
They can be calibrated to measure nearly any gas or
liquid, because their principles of operation are simple
and well understood. The flow indication is obtained
from a balance of the fluid forces underneath the float
