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 ...

Pressure is the amount of force applied per unit area. Pressure can be measured by a pressure gauge, but it is important to know the type of pressure the gauge is reading. This article will cover the ...

Flow measurement is one of the most important aspects of process control after pressure and temperature. This is one of the variables most used and important for most of the processes in a variety of ...

Two-wire transmitter technology came about from an agreement among various instrument suppliers in the 1950s to standardize on 4-20 mA current loops as a means of sending a flow, temperature, pressure ...

Nuclear power plants measure the dynamic response of their safety-related pressure, level, and flow transmitters for one or more of at least four reasons: To comply with a plant’s technical ...

Pressure transmitters used in the process industries are very durable and reliable instruments. Even so, they still require periodic maintenance and calibration to ensure optimal performance. This is ...

We describe a method based on a Fabry-Perot interferometer at the tip of an optic fiber with a diameter of 0.25 mm for direct measurement of tracheal pressure in pediatric respiratory monitoring. The ...
