DVZ-...S00 DVZ-...F00 DVZ-...L44 DVZ-...L44 DVZ-...C... DVZ-...L0 (usage with AUF-000) (compact electronics) DVZ-...L4 Description The compact KOBOLD Vortex fl ow meter Model DVZ is used for measuring and monitoring smaller and medium-sized fl ow of low viscosity, water-like liquids in pipes. The device works using the vortex principle, making it virtually maintenancefree. This involves the installation of a sharp-edged object (the vortex generator) in the fl ow duct. Vortices are created behind the object whose frequency is proportional to the velocity of fl ow of the liquid. The fl ow volume can be determined with a very great degree of accuracy by measuring the vortex frequency. This achieves a very high linearity over the whole measuring range. The device can be fi tted with switching, frequency or analogue outputs. There is also an optional compact electronics package that includes a digital display, and both a switching and analogue output. Dosing and metering electronics are currently being developed.
