摘要
点式超声波流速仪根据超声相位偏移测量原理设计而成。其核心是装在壳体内的单片机测控系统，能实时、连续、自动测量及显示特定测点的流速和流向。由于采用了声速补偿方法，保证了测量精度。
Tie pcint-type ultrasonic flow meter is designed with ultrusonic phase shift principle, its core is a single chip computer measurement control system which is fixed in the shell, so it can measure and display the velocity of flow and direction of flow continucusly and automatically in real time. Owing to adoptling the compesation of velocity of flow, the measurement precision is ensured.
