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 ...

The trunnion ball valve design maintains a reliable seal under high differential pressure without excessive torque, ensuring ...

At large institutional facilities and educational campuses, particularly those located in colder climates, steam flow measurement is a critical challenge. Facility operators want to accurately track ...

Recent advances in flow sensing have resulted in more accurate, durable, and economical meters. Increasingly important is the ability to interface meters with a computer for instantaneous flow readout ...

AutomationDirect’s ProSense DPTW series differential pressure transmitters are precision engineered for accurate differential or gauge pressure measurement of a wide variety of liquids, gases, and ...

The operating software allows the field technician to specify the type of test and the number of traverse points to be sampled, perform leak and calibration checks on the pitot assembly, and then ...

The transmitters directly calculate the mass flow or standard volume flow for gases, vapors and liquids with dynamic flow compensation from three process variables of differential pressure, absolute ...

Some of the applications mentioned here require a room that maintains a higher or lower pressure compared to the surrounding ambient environment. If the isolated room has greater air pressure, it is ...

Feedwater control valves play a critical role in boiler operation. One important parameter of their design is the pressure drop at the rated condition as well as off-design conditions. However, ...
