files/img/hardware/kritische-duesen.jpg

Sonic Nozzles are internationally recognized as the ideal solution for gas flow measurement and Calibration.

Rangeability and accuracy are limited only by the choice of pressure transducers used for measurement of the upstream flow.

PC based data acquisition systems offered with PTB/DKD approved algorithm for mass flow calculation.
