Product Description

Principle:

LXW Series vortex shedding flowmeter is manufactured and designed according to the principle of Kármán Vortex Street.

When the fluid flows past a bluff body in the measuring tube, vortices are alternately formed on each side of this body. The frequency of vortex shedding down each side of the bluff body is directly proportional to mean flow velocity and therefore to volume flow. As they shed in the downstream flow, each of the alternating vortices creates a local low pressure area in the measuring tube. This is detected by sensor and fed to the electronic processor as a primary, digitized, linear signal.
