| Abstract: | Applying the pseudo code digital correlated technology in the ultrasonic level measurement to compose the level measuring system of the steam drum. The relative characteristics of the pseudo code are analyzed. With discussion on the principle of ultrasonic level measurement based on pseudo code technology, the level measuring system is designed. It is proved that the system has a high measuring accuracy and could be applied in the measurement of drum water level. |
