Fluid velocity transducer

摘要: A transducer for measuring the relative velocity of movement a body in liquid or gaseous medium employs no reciprocating parts and functions by sensing force applied to diaphragm (6) die its through towards diaphragm. The speed makes use Hall effect solid state device (7) that produces an output voltage when magnetic field is either surfaces. level proportional positive direction, i.e. acts on (Figure 1). Since takes into account differential forces, unwanted common acting both diaphragms simultaneously will have measured speed. tubular (1) which located may be made from any non-magnetic material suitable environment used.
