2.1 Device description
Vortex flowmeters measure and display the flow of flammable and non-flammable gases and
liquids. The signal converter includes either a 4...20 mA signal output with optional HART
®
communication or a bus connection. There are bus connections available according to the FISCO
model for connecting to the Foundation Fieldbus or Profibus PA. Signal converters with signal
output have a separate binary output and a separate current input.
The VTX3 W remote version consists of the SV18 flow sensor and the KV18 ..i-Ex signal converter.
2.2 Type code
The safety description code consists of the following elements*:
The remote version consisting of the flow sensor SV 18 and the signal converter KV 18 020 is
called the VTX3 W.
