TL;DR: In this article, a new methodology for measurement of the instantaneous average exhaust mass flow rate in reciprocating internal combustion engines is presented, which is used to determinate real driving emissions on light duty vehicles, as part of a Portable Emission Measurement System (PEMS).

TL;DR: In this paper, the performance of a turbine meter in two-phase (water/air) flow in a vertical pipe is assessed and a technique for using measurements of the fluctuations in the turbine meter rotor velocity to determine void fraction (= air flowrate/total flowrate) is described.

TL;DR: The measurement of flow is a technique used in any process requiring the transport of a material from one point to another and can be used for quantifying a charge for material supplied or maintaining and controlling a specific rate of flow.
Abstract: Publisher Summary This chapter discusses the measurement of flow as it is a technique used in any process requiring the transport of a material from one point to another It can be used for quantifying a charge for material supplied or maintaining and controlling a specific rate of flow In many processes, plant efficiency depends on being able to measure and control flow accurately Properly designed flow measurement systems are compatible with the process or material they are measuring They must also be capable of producing the accuracy and repeatability that are most appropriate for the application Flow can be measured as either a volumetric quantity or an instantaneous velocity The basic principles of flow measurement are: streamlined and turbulent flow, viscosity, and so on Streamlined flow in a liquid is a phenomenon, and viscosity is the frictional resistance that exists in a flowing fluid
