Known as the Rotary Drag valve, the new device represents a major step forward in valve engineering because it combines the best features of ball valves and control valves. Developers of the product ...

In one such experiment on suspended animation, using a mixture of gases which required to be present in precise proportions within a mixture at very low flow rates, Dr. David Kraus, Ph.D. experienced ...

The FCI ST100A Flow Meter helps them more accurately control the application of ammonia (NH3) for nitrous oxide (NOx) removal ...

Precisely formulated gas mixtures with known concentrations of particular target gases are referred to as calibration gas standards. To guarantee the accuracy of gas concentration measurements, almost ...

As today's science and engineering focuses more and more on micro technology, the requirement to be able to measure and control extremely low gas mass flow rates has become very important. With ...

A mass flow controller (MFC) is a device that precisely measures and controls the flow rate of gases. It is widely utilized in industrial processes, research, and analytical applications where precise ...

We report the design, fabrication and characterization of a microelectromechanical systems (MEMS) flow control device for gas chromatography (GC) with the capability of sustaining high-temperature ...

Integrated slug-flow optimization can mitigate flow problems in a wide range of both offshore and onshore operating conditions. Slug flow is one of the most common flow states in horizontal and ...

The FMA7400/7500 (elastomer seal) and (-SS) (metal seal) Series thermal-mass flowmeters and controllers overcome the limitation of many thermal-mass flow units when changing gas types. The unit’s ...

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 ...
