超声波流量计基本参数理论分析的基本任务是研究流速(或流量)与高频电信号的某一参数之间的关系,这个电信号是穿过被测液体之后的超声波,经接收的压电元件变换得来的。上述参数可以是在双通道和单通道相位测量的电子系统中的正弦电压的相位,脉冲的发送和接收之间传播的时间—在脉冲系统中和在 Ultrasonic flowmeter basic parameters Theoretical analysis of the basic task is to study the flow rate (or flow) and the relationship between a high-frequency electrical parameters, the electrical signal is through the measured liquid ultrasonic, the received piezoelectric element Transform it. The above parameters may be the phase of the sinusoidal voltage in the electronic system of dual-channel and single-channel phase measurements, the time of propagation between the sending and receiving of pulses - in the pulse system and at
