Measuring air flow in an HVAC duct can be a tricky business. Paddle wheel and turbine flow meters introduce not only resistance but maintenance issue due to accumulated dust and debris. Being able to ...

Rather than building ever-larger Coriolis, vortex or ultrasonic sensors, engineers can use smaller measuring paths and combine their outputs to accurately measure flow in large-diameter pipelines.

Titan Enterprises reports on increasing use of its proprietary Atrato ultrasonic flowmeter technology for medical applications including real-time drug monitoring, metering of coolants for ...

Ultrasonic flow measurement exploits sound waves to determine the velocity and volume of fluids in pipes and open channels. The most common approach, the transit-time method, measures the difference ...

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 ...

Ultrasonics refers to signals that are above the human hearing span (>20 kHz), and usually in the 40- to 70-kHz range. These signals are used like radar—they’re radiated toward a target and reflected ...
