Comparison of standards for liquid flow up to 28.5 t/h

Project Description

A coriolis flowmeter (connection diameter: DN50) will be calibrated by the participants and results will be reported as a comparison.

The project has been completed and the report can be downloaded here>>

A DN 40 ABB coriolis mass flowmeter was used as a transfer standard in the flow range from 3 t/h to 28.5 t/h. The meter tested on flowrates 3, 6, 14, 20, 28.5 t/h with 5 repeats.The statistical data of the flowmeter were included in the uncertainty value. The country and flow evoluation were made for each flowrate and the results of all partipiciants were consistent.

Progress Report 2019-04-10

Stability evaluation of the transfer standard was made. Country and flow rate evaluation is going on according to these values of flowmeter.
The comparison results were evaluated as mass flow because of the problem with the temperature sensor of the transfer meter.
