Measurement of Flowing Liquids - Methods and Influences

摘要

Measuring the volume of flowing liquids in closed pipes is the basis for many cases in practice. The traceable unit volume as a function of temperature, pressure, density and flow rate is often carried out with gravimetric weighing systems. Different calibration methods and operating modes are used for each single measurement. For a precise uncertainty analysis, several influences are discussed. For most influences measuring advices are introduced.
