Volume flow – rotary piston CONTOIL® (Aquametro)

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.


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.
