摘要

摘要: 流量是工业检测重要参数之一。流量检测技术随着微机械电子系统（MEMS）技术的发展与应用，向着小型化、高精度、智能化的方向发展。基于MEMS技术设计了一种梁膜结合的压差式流量传感器结构，分析了其基本工作原理，采用硅微加工工艺对传感器进行了流片加工，然后对封装完成的传感器样机进行了气流和水流静态性能测试。气流测试灵敏度为0.3508mV/（ms^-1）²，测试基本精度为0.5885%FS；水流测试灵敏度为41.5241mV/（ms^-1）²，测试基本精度为0.9323%FS。结果表明，所设计传感器具有较高的灵敏度与基本精度，从而能完成流量信号的检测。

Abstract: Flow is one of the important parameters in industrial detection. With the development and application of the Micro Electro-Mechanical Systems (MEMS) technology, flow detection is developing towards miniaturization, high precision and intelligence. A MEMS beam-membrane structure based differential pressure flow sensor is designed, and its working principle is analyzed. The sensor is fabricated by the silicon micromachining technology, and then the airflow test and water flow test are conducted. The sensitivity by the airflow test is 0.3508mV/(ms^-1)² and the basic accuracy is 0.5885%FS. The sensitivity by the water flow test is 41.5241mV/(ms^-1)² and the basic accuracy is 0.9323%FS. The results show that the designed sensor has sufficient sensitivity and basic accuracy for the flow measurement.
