Optical flow meter Principle Instrumentation Tools

A relatively recent development in industrial flow measurement is the use of light to measure the velocity of a fluid through a pipe. One such technology referred to as Laser-Two-Focus (L2F) uses two laser beams to detect the passage of any light-scattering particles carried along by the moving fluid: (adsbygoogle = window.adsbygoogle ...
