Author's Workplace：Shandong Natural Gas Pipeline Co., Ltd.,

Key Words：Flow meter; Noise reduction; Signal processing; SNR

Abstract：

Noise interference is an important factor affecting performance of ultrasonic flow meter. Conducted is analysis on noise sources and introduced are several kinds of commonly used noise control technologies. Combined with a typical case in production, analyzed are the causes affecting performance of ultrasonic flow meter and proposed is a reasonable solution. Operation results show that ultrasonic flow meter noise reduction effects are good and ultrasonic flow meter can accurately meter rate of flow after reconstruction.
