The Bell Prover, a primary standard gas calibration system, is used to accurately measure a displaced volume of any non-hazardous gas at a constant pressure over time so that precise flow rate measurement can be performed.
The popular CFlow+ LabVIEW based data acquisition and control software ensures optimal man-machine interface and ease of operation.
This PC based, gas calibration system offers truly exceptional accuracy and stability using advanced flow calculation algorithms and compensation techniques.
