| Abstract: | 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. |
