The compact KOBOLD Vortex flow meter Type DVZ is used for measuring and monitoring smaller and medium-sized flow of low viscosity, water-like liquids in pipes. The device works using the vortex principle, making it virtually maintenancefree. This involes the installation of a sharp-edged object ( the vortex generator ) in the flow duct. Vortices are created behind the object whose frequency is proportional to the velocity of flow of the liquid. The flow volume can be determind 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 fitted with swittching, frequency or analogue outputs.
There is also an optional compact electronics package that includes a digital display, and bot a switching and analogue output. Dosing and metering electronics are currently being developed.
