Sonic
Nozzle Calibration System for Gas Flowmeters
TCV Series Sonic Nozzle
Systems
Sonic Nozzles are internationally
recognized as the best Flow
Transfer Standard for
gas flow measurement and Calibration.
The TCV series of calibration stands operating
under our CFlow+ data acquisition and control software feature
nozzle manifolding and pressure control for optimal flexibility.
This PC based, gas calibration system offers truly exceptional
accuracy and stability using advanced flow calculation algorithms
and compensation techniques.
