Why isn this mass flow meter indicating flow rate, temperature or totalization correctly ?
Check the flow meter’s functionality, specification, installation, and validate the comparison standard. If you suspect that your newly installed flow meter isn’t indicating correctly, start your troubleshooting procedure with a flow meter functionality test, but don’t stop there. Review your application parameters against the Gas Flow Meter Selection Chart and seek advice from the product vendor if your flow meter appears to have been incorrectly specified. Next, confirm that the flow meter has been installed per the manufacturer’s installation guidelines. Finally, check the measurement method or calculation that was used as the reference or comparison standard. Many “reference” methods are, at best, estimates (generic blower curves, valve positions, operator experience, stoichiometric calculations). As a last resort, make zero and span adjustments.
