Ultrasonic energy is widely used to sense the presence of nearby objects and even determine their distance if needed, as well ...

Flow meters are used to measure the rate of flow of liquids or gases, just like electric meters measure the amount of electricity consumed. However, unlike electric meters, which are either ...

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 ...

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 ...

In January, we looked at one of the most commonly used formulas (Formula 1) in hydronic heating design: 500 = fluid factor based on water as the system fluid This formula can be used to determine the ...

A graph of the scaling relationship between fluid flow and fracture stiffness is shown. The shape of the symbol indicates the fracture length scale from 0.0625 meter (circles) to 1 meter (triangle) ...

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 ...
