CONTOIL® VZF SERIES DN15-50 WITH ELECTRONIC DISPLAY

The volume flow 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.

Construction

Rotary piston, guide roller and drive are the only moving parts in contact with the liquid. Their movement is transmitted by a magnetic coupling through a sealing plate. The hydraulic part is completely separated from the totalising module.

CONTOIL® VZF II SERIE DN15-50 – HERSTELLER: AQUAMETRO OIL & MARINE

The CONTOIL® oil / fuel flow meter mechanical display models type VZF II and VZFA II:

Measurement of the mass flow rate
Integrated temperature sensor
Simple burner setting with flow rate display
Simple consumption monitoring with limit switch Qmin/Qmax
Manual dosing, with resettable totalizer, can be installed on the pressure or suction side of a pump
Space-saving installation, as no straight inlet and outlet sections are required
Flexible installation of the meter in a horizontal, vertical or inclined position
Accurate measurement result, as the meter reading is independent of the temperature and viscosity of the medium
Minimal downtime costs thanks to simple function monitoring, quick error analysis and the option of simple on-site repairs
