The transducer in Ultrasonic Level meter sends out high frequency ultrasonic pulses.When a pulse hits liquid surface, it is reflected back.The reflected ultrasonic wave is received by the transducer and converted into an electronic signal through piezoelectric crystals.The time interval between transmitted ultrasonic pulse and received ultrasonic pulse is directly proportional to the distance between transducer and liquid surface。the distance between transducer and liquid surface.is calculated from the time interval between transmitted ultrasonic pulse and received ultrasonic pulse.
 

According to the above principle, If you want to improve the measurement accuracy of ultrasonic level meter, you must ensure that the time difference between sending and receiving pulses t and the sound velocity (c) in the current environment are monitored very accurately.
 

ULever Meter R & D personnel firstly improve the basic time base accuracy of MCU and improve the response speed in the monitoring of time difference t. So as to ensure quick response and accurate time.Then use the time redundancy expansion technology to increase the sampling points to enhance the judgment of the echo signal.Monitoring of sound velocity C adopts multi-point step temperature monitoring method.When the sound velocity value at the current temperature is accurately obtained, and the temperature change is monitored in real time during the working process to correct the sound velocity value. The UVUS type of Ultrasonic Level meter launched by ULEVER meter.are designed to meet the needs of users. Ulevel Mete recently launched four styles ultrasonic level meter, Integrated Ultrasonic Level meter、Split Ultrasonic Level meter、Small volume Ultrasonic Level meter、small dead zone Ultrasonic Level meter. They have the characteristics of high accuracy, quick response and strong adaptability.
