The Kobold DVZ series vortex flow meter is the perfect solution for applications where
reliability and low cost are desired.
The Kobold DVZ series vortex flow meter senses the flowrate of low viscosity liquids using
the vortex shedding principle. A small obstruction called a bluff body is placed in the
flowpath. As fluid flows across the bluff body, a small low-pressure area called a vortices
is created just behind the bluff body. The position of the vortices alternates to either side
of the bluff body in a uniform pattern. The frequency of the vortices shift is directly
proportional to flowrate. This shift in the vortices is detected by a very sensitive pressure
sensor and processed as a flowrate signal.
The Kobold DVZ series vortex flow meter has no moving parts and thus is very reliable. The
Kobold DVZ series vortex flow meter is available with a Ryton body and a choice of either
nickel plated brass or 316 stainless steel fittings. The bluff body is available in either
ryton or ceramic, which has excellent long term wear characteristics. The available outputs
are frequency, 4-20 mA, adjustable relay, and compact electronics with digital flowrate display,
4-20 mA output and adjustable transistor switch options.
