英文摘要：

In mobile bed experiments, the measurement of water level needs to be real-time and automatic. This paper represents the technology of fast measurement for water level and software platform constructing. The system consists of pressure sensor and analogue- digit transform card, the digit quantity is processed by the software. In software platform development, design pattern is applied to make the system extendable and maintainable.
