Both gas and liquid flows can be measured in volumetric or mass flow rates. With noncompressible liquids, these measurements are nearly the same, sans the effects of temperature. With compressible ...

Embedding Methodology in the Control System of a Plant Increases Its Utility Biotech processes should be standardized as much as possible to produce optimum product yields. On-line off-gas analysis is ...

Oil field operators can use several practical equations for calculating flow rates of natural gas through venturi gas-lift valves. For critical flow, this analysis derived such equations from a ...

Industrial emissions, automobile exhaust and household waste produce a wide range of pollutants. These include chemical gases such as NOx as well as fluorocarbons. Together with CO 2 and methane, they ...

Equipment for gas chromatography, liquid chromatography and mass spectrometry is complex, with multiple subsystems that control the flow of sample analyte, carrier gas and solvent fluids. The ...

Three additions to the GF100 Series offer higher flow, improved accuracy and a faster response time for gas flow control in semiconductor and LED manufacturing processes. The GF101 high-purity mass ...
