The intelligent vapour recovery system VARECO Plus (Stage II) with the vortex flow sensor works completely automatic, self regulating and self monitoring, independent of temperature, pressure and density. It continually controls and regulates the vapour flow during the fuelling process.
The system is equipped with additionl interfaces (RS232 and RS485) for the connection to the dispenser calculator or POS system and can also be optionally adjusted, e.g. with LAN or WLAN.
VARECO Plus meets all the standards as the 21 BImSchV (German Federal Pollution Control Act) and the European Standard EN 16321.

The VARECO Plus system can also be used as a vapour recovery monitoring system purely.
