New flow meter CONTOIL® VZF3 with Modbus protocol

The CONTOIL® VZF3 flow meter brings a new level of accuracy and reliability to fuel consumption monitoring and serial communication via Modbus RTU over RS-485. Designed for demanding industrial and marine applications, it combines advanced functionality with a user-friendly design to deliver accurate, dependable performance.

Built with future requirements in mind, the modular architecture of the CONTOIL® VZF3 supports optional plug-in modules, enabling easy expansion and customization as application needs evolve. This design ensures long-term adaptability without compromising performance.

CONTOIL® VZF3 - a benchmark in precision,  connectivity and usability.
  • Mass flow measurement
  • Integrated temperature sensor
  • Simple burner setting with flow rate display
  • Simple consumption monitoring with limiting value switch Qmin/Qmax
  • Manual dosing feature, with a resettable counter be mounted on the pressure or suction side of a pump
  • Space-saving installation, because no straight inlet/outlet sections are required
  • Flexible mounting of the meter in horizontal, vertical or inclined positions
  • Accurate measurement result, since the reading is independent of the temperature and viscosity of the fluid
  • Minimum failure costs due to simple function monitoring, rapid fault analysis and the possibility of simple repairs on site
  • For information about the PEEK flowmeter type, please contact our sales department (Contact)

Areas of application

  • To measure heating fuel consumption by oil burners (for example, in heating boilers, industrial furnaces, tar processing plants)
