The radar measurement method plays a progressively important role in the wastewater and water field. This is specifically revealed by the "Metering outside of the medium" trend. Flow measurement by ...

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 ...

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 ...
