PERFORMANCE IMPROVEMENT OF LIQUID FLOW CALIBRATORS BY APPLYING SPECIAL MEASUREMENT AND CONTROL STRATEGIES

Rainer Engel, Hans-Joachim Baade, Andreas Rubel
  • Abstract:
    PTB?s new "Hydrodynamic Test Field", which represents a high-accuracy water flow calibration facility, will serve as the national primary standard for flow measurands: volumetric and mass flow rate, respectively, and total flow measurement, i.e. the quantity of fluid (volume or mass) passing a flowmeter. Owing to this application aspect, the main design goal was to realize a total expanded measurement uncertainty as low as 0,02 % for total volumetric flow-rate measurement. To meet this decisive requirement, low-uncertainty components were combined with state-of-the-art measurement and control strategies.
