Ultrasonic flow meters are non-invasive devices that use acoustic vibrations to determine the flow rate of a liquid. There are two types of ultrasonic flow meters – Doppler and transit time. Both ...

The Doppler effect, discovered in 1842 by Christian Doppler, is familiar to most of us; stationary observers of waves such as sound waves will see wavelengths that depend on the relative motion ...

Magnetic flowmeters are one of the few technologies (along with Doppler ultrasonic) that handle solids-laden and conductive ...

The Indus Doppler Flow Velocity System is a high-frequency, real-time pulsed Doppler measurement tool with built-in data processing software intended to assess small animals' cardiovascular health.

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.

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 ...
