Vortex Flow Meter (KVO)

Vortex Flow Meter (KVO)

According to proven laws of physics, the frequency at which the vortices are alternately shed is directly proportional to the flow velocity. As flow passes a bluff body in the flow stream, the vortices create low and high pressure zones behind the bluff body, or shedder bar. The KVO uses a piezoelectric crystal sensor to detect the pressure exerted by the vortices on the velocity sensor. The piezoelectric converts these “pulses” into electrical signals. The meter uses an all welded sensor design to create a robust sensor and to minimize potential leakages.
