为什么选择超声波液位计?
Why choose ultrasonic liquid level meter?

因为,超声波液位计由声波的发射和接收之间的时间来计算传感器到被测物体的距离。无机械可动部分,可靠性高,安装简单、方便,属于非接触测量,且不受液体的粘度、密度等影响精度比较低,所以选择。
Because the ultrasonic liquid level meter calculates the distance from the sensor to the measured object by the time between the transmitting and receiving of the sound wave. No mechanical movable part, high reliability, simple installation, convenient, belongs to non-contact measurement, and is not affected by the viscosity and density of the liquid, the accuracy is relatively low, so choose.

超声波液位计特点及工作原理
Characteristics and working principle of ultrasonic liquid level meter
超声波液位计是由微处理器控制的液位数字仪表。在测量中超声波脉冲由传感器发出,声波经液体表面放射后被传感器接收,通过压电晶体或磁致伸缩器件转换成电信号,由声波的发送和接收之间的时间来计算传感器到被测液体表面的距离。超声波液位计采用非接触测量,对被测介质几乎不受限制,可广泛用于液体固体物料高度的测量。
Ultrasonic liquid level meter is a digital liquid level instrument controlled by microprocessor. In the measurement, the ultrasonic pulse is sent out by the sensor, the sound wave is radiated by the liquid surface and then received by the sensor, which is converted into electrical signal by piezoelectric crystal or magnetostrictive device.

Ultrasonic liquid level meter adopts non-contact measurement, which is almost unlimited to the measured medium. It can be widely used in the height measurement of liquid and solid materials.
