4. Regulation Use
Any use of the Compact Vortex Flowmeter, model: Y-DVZ45001/PS25, which
exceeds the manufacturer’s specifications, may invalidate its warranty. Therefore,
any resulting damage is not the responsibility of the manufacturer. The user
assumes all risk for such usage.
5. Operating Principle
The compact KOBOLD Vortex flow meter Type Y-DVZ45001/PS25 is used for
measuring and monitoring smaller and medium-sized flow of low viscosity, water-
like fluids in pipes. The device works using the vortex process, making it virtually
maintenance-free. This involves the installation of a sharp-edged object (the
vortex generator) in the flow duct. A vortex is created behind the object whose
frequency is proportional to the velocity of flow of the fluid. The flow volume can
be determined with a very great degree of accuracy by measuring the vortex
frequency. This achieves a very high linearity across the whole measuring range.
The device can be fitted 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.
