Product Overview body detection probe and the corresponding electronic circuits and other components LUGB-V generated by the vortex flowmeter is designed vortex flow field. When the body fluid flows through the vortex, its sides formed two rows of alternating vortex, this vortex is called Karman vortex street. Strouhal on the basis of Karman vortex street theory proposed the velocity is proportional to the frequency of Karman vortex fluid, and gives the frequency and velocity relationship:
f = St × V / d
Where:
Vortex frequency of f
The average flow rate in both sides (m / s) V vortex
St 斯特哈罗尔 coefficient (constant)
These alternating vortices to form a series of alternating negative pressure, which acts on the detection probe, they form a series of alternating electrical signal converted by the preamplifier, shaping, amplification processing, output and Vortex synchronization proportional to the pulse frequency signal (or standard signal).
