| Abstract: | In the operation of 600 MW direct-air cooling unit in Datong power Generation Corp.,the reliability of boiler drum's,water level measurement was low.Through analysis the cause of larger error of original water level measurement device was defined and the retrofitting scheme was put forward,i.e.,to adopt the built-in balancing vessel measurement technology to retrofit the original drum's water level measurement mode.The retrofit result showed that,after the buillt-in balancing vessel measurement technology was adopted,the stability and accuracy of drum's water level measurement were obviously raised. |

| Keywords: | drum's water level reference water column differential pressure of water level built-in balancing vessel |
