推荐一种利用弯管作为流速传感器的测量系统,对圆形截面管道中的风量进行检测。根据当前工况下的温度压力折合到标准状态时的体积流量,从而可消除温度、压力变化对测量的影响,将该值作为送风流量的测量值,并将其转换成1～5 V DC标准电压输出信号和数字数出信号提供给DAS系统和自动调节系统使用。实践证明,这种方法是有效的,使风量测量的可靠性和准确性显著提高。
A measuring system that uses elbows as a flow sensor is recommended to detect the amount of air in a circular sectioned pipe. According to the current conditions under the temperature and pressure into the standard state when the volume flow, which can eliminate the temperature and pressure changes on the measurement, the value of the supply flow measurement, and convert it into 1 ~ 5 V DC Standard voltage output signal and digital output signal to the DAS system and automatic adjustment system. Practice has proved that this method is effective, so that the wind measurement reliability and accuracy significantly improved.
