Abstract

In this paper, a metrological control proposal is described for exclusive application to ultrasonic flowmeters (USMs) operating at low (atmospheric) pressures. This is based on tests performed on 2 new flow meters DN150 (6") which were calibrated at first in PIGSAR (Germany) using natural gas at high pressure, as test fluid, and later characterized by air at atmospheric pressure in CDT de GAS (Columbia).
