To measuring the content of suspended sediment in the river on line,an U tabe sensor of Vibrations based CAN bus is applied. This paper briefly introduces the operational principle of the U tube sensor of vibrations and then designs a U tube sensor of vibrations based CAN bus.%为了实时监测河流中含沙量,提出了一种基于CAN总线的振动式U型管智能传感器.介绍了振动式U型管传感器的工作原理及基于CAN总线振动式U型管传感器的系统组成.
