A versatile flow meter for oil, heavy oil and many other oil-like liquids. It is used for efficient consumption measurement of heat burners and various combustion engines. A reliable solution for any application where oil is consumed.
Proven mechanical flow measurement technology for simple integration and dependable onboard operation
With the CONTOIL® series VZF II we offer a modular system for consumption measurement. The basic module of the CONTOIL® series is the well-proven piston meter, which can be extended with a mechanical or electronic display. Both VZO and VZF II offer diverse options of data transfer and can also be exchanged during operation. This kind of upgrading with communication modules is unique and enables uninterrupted operation of the system.
Features:
- State-of-the-art design
- Electronic counter, mass flow, volume flow indication, multiple output signals
- Integrated temperature sensor
- No straight inlets or outlets required Independent of viscosity and temperature
- High vibration resistance
- Optional: metrological type approval
- Automatic medium switch based on temperature

Operating principle
Technical Specificationen
Models
CONTOIL® fuel oil meters work on the volumetric principle of rotary piston meters (positive displacement meters). The main features of this measuring principle are large measuring ranges, high accuracy, suitability for high viscosities, and independence from power supply. Flow disturbances do not influence proper operation
