| Abstract: | Airflow online measurement,which used dynamic pressure mean pipe combined difference pressure transmitter,is presented. The method can realize real time measurement when there is no straight pipe section or airflow is not stable. Dynamic measuring of traction motor cooling airflow during running of locomotive can also be available using this method. |
