By incorporating high-performance digital signal controllers (DSCs), with their integrated architectures and small footprints, designers can simplify Doppler-based sensing systems, enhance their performance, and reduce development cycles.

Flow sensors are used to measure both gas and liquid flows in many monitoring and control applications. Flow can be variously defined (e.g., mass, volume, laminar, turbulent). The amount of a substance flowing (mass flow) is usually the one of interest, and if the fluid's density is constant, a volume flow measurement is generally the easiest to perform. Some technologies work for both gas and liquid flow; others are specific to what they are measuring.

We're mammals and we shed. We know this, plumbers know this, and the technical operators at the Wet 'n Wild Water Park in Orlando, FL, definitely know this.

You may have thought about using a rotameter to satisfy your flow measuring requirements. But do you really know enough about these simple, cost-effective devices to make the best decision? You will after you read this tutorial.

Originally developed to control gas vapor deposition in semiconductor fabrication, mass flowmeters and controller scan now be found in almost every industry that requires precise measurement or control of low-flow clean gases.

SBD underscores that sensor technology development should be highly focused on specific applications, which have significant growth potential in the marketplace.

Part 1 of this two-part article describes the applications, performance characteristics, mode and theory of operation, calibration, installation and maintenance procedures, and the design and construction of axial turbine flowmeters.
