Flow Metering There are millions of gas and water meters installed all around the globe. Wiegand technology can help service providers and consumers by making these meters smarter and more efficient. A permanent magnet can be mounted on the meter 's rotating shaft, close to a Wiegand sensor. As the shaft turns, the rotation of the magnetic field triggers a pulse. The strength and duration of each current pulse is independent of how quickly or slowly the shaft rotates. This is one of the major benefits... (read more) -

Eastern Instruments
CentriFlow Meter: More Accurate than Impact Meters How It Works. The secret to the CentriFlow® Meter's accuracy lies in its zero-friction design, which is based on the principal of centripetal force. As particles travel over the measurement pan they travel in a circular path that accelerates them inwards towards the center of the circle along a radius. Because the particles are sliding across the curved measurement pan in this circular motion, the acceleration of the particles generates a centripetal force in the direction of the acceleration...

Infrasound in the flutter-jump display of Capercaillie (Tetrao urogallus ): signal or artefact?
The failure of the subwoofer to produce infrasound could only be detected with specialized infrasound-sensitive equipment (i.e., an infrasound -sensitive sound level meter or recording equipment), because human hearing typically rolls off below 40 Hz (Moss and Lockie 1979).
