The SMF Mobile Flowmeter is designed as a compressed air operated gas flow meter. The calibration flow rate is adjusted with a combination of a high precision pressure regulating valve and sonic nozzles.

The calibration of the test element is performed in the following configuration: Compressed air – supply – SMF – test element – atmosphere.

Data acquisition and evaluation is carried out on the basis of a PC with software programmed in LabVIEW.
