Liquid level sensor

SFU30B Ultrasonic Level Transmitter

Ultrasonic liquid level meter sends out ultrasonic pulse by sensor (transducer). The sound wave is received by the same sensor or an ultrasonic receiver after it is reflected by the liquid surface and is converted into electrical signal through a piezoelectric crystal. The transmission time of the sound wave is proportional to the distance from the sound wave to the surface of the object, the distance from the sensor to the surface of the measured liquid (solid) is calculated by the time between the transmission and reception of the sound wave.

Introduction:

Ultrasonic liquid level meter sends out ultrasonic pulse by sensor (transducer). The sound wave is received by the same sensor or an ultrasonic receiver after it is reflected by the liquid surface and is converted into electrical signal through a piezoelectric crystal. The transmission time of the sound wave is proportional to the distance from the sound wave to the surface of the object, the distance from the sensor to the surface of the measured liquid (solid) is calculated by the time between the transmission and reception of the sound wave.

Features:

- It has strong anti-interference ability and can be applied to the liquid level measurement in harsh environment

- Built-in temperature sensor can realize real-time temperature automatic compensation function

- Multiple output types can meet different industrial field interface requirements


- Minimum blind area is 6 mm, which has the leading position in the field of measurement in China


Applications:

- Liquid level inspection of tap water and sewage treatment

- Liquid level inspection of food processing

- Liquid level inspection of collection well and biochemical pool


- Liquid level measurement of various slurry
