Primary standardization of pressure

The methodology for the implementation of pressure standardization in Inmetro's Pressure Laboratory is based on the dimensional measurement of a piston cylinder assembly with 50 mm of diameter. The measurement includes optical and mechanical contacts for the measurement of shape and diameter

  • f the assembly. A numerical post-processing procedure is applied to generate accurate three-

dimensional data of the surfaces of the cylinder piston assembly required to determine its area.

Research projects

System of mass flowmeters calibration from 3 kg/h to 120 kg/h using a differential pressure measurement standard.

Pressure measurements have an extensive and important application in industrial processes. For example, in the petroleum, petrochemical, meteorological, aerospace, aviation, etc. industries. The reliability of these measurements is associated with trade, quality, health, safety, etc. The initial objective of the research is to create a system for the calibration of low flowmeters (Coriolis), used in the field, from differential pressure and mass measurements. One of the applications of differential pressure is in flow measurement, which requires increasingly better

  • uncertainties. The meters used in the flow measurements

require a calibration with better accuracy to guarantee its performance.
