  • Simplifies consumption optimizing

Operating principle :

Function :

CONTOIL flow meters work on the volumetric principle rotary piston meters (positive displacement meters).

The main features of this measuring principle are large measuring range, high acuracy, suitability for high viscosities and independence from power supply;flow disturbances do not influence proper operation.

Leading manufacturrs of oil burners and operators of hearing systems, ships or diesel engines relyon CONTOIL fuel oil meters – and good reasons.
