Operating principle

The product enters the measuring chamber following the direction of the arrow. The rotor and blades assembly (1-2) is set in motion by the pressure of the liquid on blades. A certain
amount of liquid (3) is held between 2 blades and then directed to the discharge manifold. The volume of liquid measured at each rotation is therefore equal to 4 times the measured
quantity (3). The smooth curves the meter pieces provide a steady, non-fluctuating flow resulting in low head loss

Key points

Reduced pressure loss

 

0.3 to 0.5 bar at maximum flow rate.

Low maintenance costs

 

Simple and robust design with mechanical components
interchangeable between the different models.

Stability of measurements

 

Accuracy of measurement guaranteed over a period of many years without any drift in the calibration curve.

Modular design

 

Wide range of accessories for performing customized measurement applications.

Robust construction

 

Flowmeter manifold is separated from measurement chamber to eliminate any possible influence of external mechanical stresses on measurement accuracy. Few moving parts.
