流量计滤波系统和方法
摘要：
依据本发明的实施例的一种流量计滤波系统(200)包括：噪声通过滤波器(203)，其被配置以接收流量计信号的第一版本，并且从所述流量计信号中滤出所述流量计数据以剩下噪声信号；噪声计量器(204)，其被配置以接收来自所述噪声通过滤波器(203)的噪声信号并测量所述噪声信号的噪声特征；阻尼调整器(205)，其被配置以接收来自所述噪声计量器(204)的噪声特征，并且基于所述噪声特征来产生阻尼值；以及滤波器元件(206)，其被配置以接收所述流量计信号的第二版本以及接收来自所述阻尼调整器(205)的阻尼值，所述滤波器元件(206)被进一步配置以基于所述阻尼值来阻尼所述流量计信号的第二版本，以便产生滤波的流量计信号。
摘要（英）：

The embodiment of the invention discloses a flowmeter filtering system (200) which comprises a noise pass filter (203), a noise counter (204), a damp adjuster (205) and a filter component (206), wherein the noise pass filter (203) is configured to receive a first edition of a flowmeter signal and filter the data of the flowmeter from the flowmeter signal to retain a noise signal; the noise counter (204) is configured to receive the noise signal from the noise pass filter (203) and measure the noise characteristics of the noise signal; the damp adjuster (205) is configured to receive the noise characteristics from the noise counter (204) and generate a damp value based on the noise characteristics; the filter component (206) is configured to receive a second edition of the flowmeter signal and receive the damp value from the damp adjuster (205); and the filter component (206) is further configured to damp the second edition of the flowmeter signal based on the damp value so as to generate a filtering flowmeter signal.
