KOBOLD DVZ Series vortex flowmeters with no moving parts are the perfect solution for applications where reliability and low cost are desired. The DVZ Series vortex flowmeter senses the flow rate of low-viscosity liquids using the vortex-shedding principle. A small obstruction (bluff body) is placed in the flow path. As fluid flows across the bluff body, small, low-pressure areas (vortices) are created just behind the bluff body. The position of the vortices alternate to either side of the bluff body in a uniform pattern. The frequency of the vortex shift is directly proportional to flow rate. This shift in the vortices is detected by a very sensitive pressure sensor and is processed as a scaled flow rate signal. The DVZ Series vortex flowmeter has no moving parts and is thus very reliable. It is available with a PPS body and your choice of either nickel-plated brass or 316 stainless steel fittings. The bluff body is available in either the standard PPS or optional ceramic material, which has excellent long-term wear characteristics even under harsh operating conditions. Available outputs for the KOBOLD DVZ Series vortex flowmeter include pulse frequency, 4-20 mA, adjustable relay, and compact electronics with LED digital flow rate display, 4-20 mA output and adjustable transistor switch options.
