How to calibrate a metal tube float flow meter
Thread Content
The metal tube float flow meter used in the additive system has a diameter of 15, and it has been in use for 5 years. Now we would like to have it calibrated to assess its performance. Where can I take it for calibration? The location is Lanzhou; the Gansu Provincial Metrology Institute is currently unable to handle it
The gas flow rate is represented by air, and the liquid flow rate by water; then correction values are used to adjust for any deviations. To understand the specific principles and methods, just find a reference book on rotameter knowledge and read it carefully.
The China National Institute for Testing and Certification can conduct tests; for liquids, testing is done using water, and then calculations are performed using correction formulas
