Laser-Doppler flow sensors differ from other types in that they measure flow at a point, not over an entire area. They are typically used to scan a flow field to gain specific details.

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.

The MR flow transmitter combines state-of-the-art digital signal processing with the technology of a piston-type variable-area flowmeter.

Accessing real-time data provides operators with continuous data on flow rates, pump performance and well levels, allowing ...
