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 ...

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.

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

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 ...
