Mass flow measurement is the basis of most technoeconomic formulations in the chemical industry. This calls for reliable and accurate detection of mass flow. Flow measurement laboratory experiments were conducted using various instruments. These consisted of orifice plates, various sized rotameters, wet gas meter and soap bubble meter. This work was aimed at evaluating appropriate operating con...

The Venturi meter is a straightforward pipeline device used for the metering of gas and liquids. This article presents a brief summary of the creation and characterisation of the modern Venturi meter, including the historic development of public domain algorithms to derive two phase (gas and liquid) flow rates from differential pressure measurements. The use of Venturi meters in multiphase oil ...

The new semi-experimental method for simulation of the turbine flow meters rotation in the transitional flow has been developed. The method is based on the experimentally established exponential low of changing of dimensionless relative turbine gas meter rotation frequency and meter inertia time constant. For experimental evaluation of the meter time constant special facility has been developed...
