I、Specification：
HBLU ultrasonic liquid level meter is a non-contact, high reliable material level measurement instruments. The transducer(probe) sends out high frequency ultrasonic pulse,was reflected back when met the surface of the measured medium,some of the reflected echo is received by the same transducer and changed into the electrical signals.Ultrasonic pulse spread by wave velocity,from launch to receive the ultrasonic pulse interval and required is directly proportional to the distance of the transducer to the surface of the measured medium to measure the level.Is widely used in power plants,metallurgy,pharmaceuticals,cement, food and other industries.

II、Main Features： 
1.Use the advanced digital filter tracking algorithm,can capture the real echo in a noisy electric and acoustic noise efficiently. 
2.Built-in temperature compensation
3.Large screen LCD backlight display
