The sensor measures the density of liquids in a microelectromechanical system (MEMS). Within the MEMS, the liquid is directed to an omega-shaped microchannel, known as the omega chip. This tiny silicon tube – it is hardly thicker than a hair – is vibrated for the purposes of the measurement. The density of the medium to be measured can be derived from the natural frequency of this oscillation: The denser the medium, the smaller the oscillation.
The sensor measures the density of liquids during the process itself – no need to go to the laboratory. Thanks to a sub-millimeter measuring channel, the properties and quality of a liquid can be precisely monitored even in confined spaces.
The conversation was highly helpful to me. I want to know about the suitable sensors that can be used for level measurements for conical tank systems. Mr. Pedro has quickly responded and explained in very ease way. It was nice interacting with him.
