Rotameter flow meters are devices that can measure the flowrate of liquids and gases. Generally, the rotameter is a tube made of plastic, glass or metal combined with a float, which responds linearly ...

Measuring exactly how much hydrogen flows through a pipe has remained an unsolved problem, ...

Until now, it has been almost impossible to measure the energy density of hydrogen precisely, but a new sensor can register ...

The flow of all fluids, whether liquid or gas, will have one of three states: laminar, turbulent, and transitional. This article discusses flow principles and pressure-based flow measurement. Laminar ...

A peak flow meter is a user-friendly, portable device that helps measure the ability of the lungs to expel air. It estimates peak expiratory flow rate which is a measure of how rapidly air can be ...

Flow transmitters provide electrical outputs that are proportional to flow inputs. They use flow meters to measure the flow of liquids and gases. Flow transmitters use three basic types of meters: ...

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 ...

The solids flow meters measure and weigh solid materials as they flow through manufacturing machinery at various stages. There are several different measurement methods used in solids flow meters, ...

The Fluid Components International ST51 flow meter is designed to measure the flow of biogases, methane, and other greenhouse gas mixtures. The flow meter comes in an explosion-proof instrument and ...

This article describes how a multivariable pressure transmitter with built-in dynamic compensation can correct for many of the errors and inaccuracies that can occur in differential pressure based ...
