Our Flow Calibration benches for liquids work based on a volumetric displacement principle. They measure the exact volume of the liquid flowing through the flowmeter under test during the calibration and compensate in real time for changes in the viscosity and temperature of the liquid.

Our Flow Calibrators are high-precision devices, which can be traced to national and international standards (PTB, LNM, NIST).

The different models of the liquid calibrators can be used for nearly all types of flowmeters, including turbines, MID, Coriolis, PD, VA, and Vortex meters.

All Flow Calibration benches have the popular CFlow+ LabVIEW based data acquisition and control software ensures optimal man-machine interface and ease of operation. This PC based, liquid calibration system offers truly exceptional accuracy and stability using advanced flow calculation algorithms and compensation techniques.
