压力传感器在给水管道阻力系数测试中的应用

摘要

The application of pressure sensor in testing water pipe resistance coefficient is introduced. During the performance of water network a thick layer of eaten rusts and sediments arose gradually. These changed the resistance coefficient and blocked the water pipe. When analyzing the water network performance, it is necessary to test the resistance coefficient of water pipe. This coefficient can be calculated with the pressure values from four pressure sensors on the pipe.%介绍了高精度压力传感器在测试给水管道阻力系数中的应用，给水管道在长年的运行中，内壁形成一层很厚的锈蚀物和沉积物，使管道阻力系数发生变化，降低了管道的通水能力。在给水管网平差计算、工况分析时要实测管道的阻力系数。通过四支压力传感器所测压力值可以计算出管道的阻力系数。
