Turbine Meter Operation, Calibration Systems, Viscosity Effects, Real Time Correction for Viscosity and Density Variation
Turbine flow meters have been an effective flow measurement technology for many years. Advancements in other measuring technologies in recent years have provided many options when selecting a meter for a flow measurement application. This has the benefit of allowing the user to select the measuring technology that provides the optimum characteristics for the specific application. The downside of all these measurement options is the user must have a significant understanding of many technologies in order to make the best educated decision when selecting the meter.
The intent of this paper is to provide the reader with a basic understanding of the operational characteristics and calibration methods of turbine flow meters. The information provided is targeted at liquid meter applications. Turbine meters are also successfully used in gas applications. The operational characteristics of gas meters are basically the same as liquid meters, however the calibration methods and procedures are worthy of a paper specific to gas applications and will not be address at this time.
