| Abstract: | This paper describes the method measuring water level in dam piezometer pipe by using dam pie- zometer pipe and intellective capacitive transducer designed using copper wire whose insulating layer is polyterafluoroethylene as pole. The proposed transducer with USB interface can realize field measurement and debugging. And RS-485 data collection web is designed based on the proposed transducer. The proposed system has a simple circuit, easy installation and has high accuracy for measuring water level. |
