Abstract: The invention presents a differential pressure type emission flow rate measuring method and apparatus and an emission measuring system using the same apparatus, capable of correcting measuring error occurring due to pulsation appropriately and enhancing the measuring precision of flow rate when measuring the flow rate of emission having pulsation.
The invention, in measuring the flow rate of an emission exhausted from an engine, determines an accurate flow rate in spite of pulsation by using a differential pressure type flowmeter as the flowmeter, resolving the detected differential pressure signal by frequency, and correcting by using a correction coefficient predetermined depending on each frequency obtained by frequency resolution.Abstract translation: 本发明提供一种差压型排放流量测量方法和设备以及使用该设备的排放测量系统，其能够适当地校正由于脉动而产生的测量误差，并且在测量排放流量时提高流量的测量精度 脉动。 本发明在测量从发动机排出的排放物的流量时，通过使用差压型流量计作为流量计，尽管存在脉动而确定了精确的流量，通过频率解析检测到的差压信号，并且通过使用 校正系数取决于通过频率分辨率获得的每个频率。
