Compact, Low Cost Inline Vortex Flow Meters<\/h3>\n

KOBOLD DVZ inline vortex flow meters for low viscosity liquids feature a long service life and low maintenenace as they do not utilize a mechanical means of measurement, where components can break or wear out, and are the perfect solution for applications requiring reliability and low cost.<\/p>\n

The DUK 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 DVZ 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.<\/p>\n

Vortex Measurement Principle<\/h3>\n

The DVZ senses flow rate using the vortex-shedding principle. A small obstruction, known as a bluff body or shedder-bar, is placed within the flow path. As flow occurs past the bluff body, small low-pressure vortices (swirls) are created just behind it. The vortices alternate to either side of the bluff body in a uniform pattern and the frequency of the vortex shift is directly proportional to flow rate. A very sensitive pressure sensor is used to detect the shifts and a scaled flow rate signal is produced.

Other Vortex Flow Meter Types<\/h3>\n

KOBOLD also offers the\u00a0DVE Insertion Vortex Flow Meter<\/a>\u00a0which is also a multivariable vortex flow meter. The\u00a0DVH Vortex Flow Meter<\/a>\u00a0is an inline multivariable flow meter for more demanding process elements.<\/p>\n
