什么是水位传感器？

水位传感器是一种用于测量固定容器中液位过高或过低的设备。按测量液位的方式可分为接触式和非接触式。输入型水位变送器是一种接触式测量，将液位高度转换为电信号输出。是目前应用广泛的水位变送器。水位传感器是一种用于测量固定容器中液位过高或过低的装置。按测量液位的方式可分为接触式和非接触式。输入型水位变送器是一种接触式测量，将液位高度转换为电信号输出。是目前应用广泛的水位变送器。水位传感器is a device for measuring too high or too low a liquid level in a fixed vessel. According to the method of measuring liquid level, it can be divided into contact type and non-contact type. The input type water level transmitter is a contact measurement that converts the level height into an electrical signal output. It is a widely used water level transmitter at present.

Where to use water level sensors?

The use of water level sensors includes the following applications:water level sensors includes the following applications:

1.Pools and tanks

2.The water level of rivers and lakes

3.Ocean water level surveyAcid-base liquid

4.Oil level measurement of oil truck and mailbox

5.Swimming pool water level control

6.Tsunami warning and sea level monitoring

7.Water level control of cooling tower

8.Water level control of sewage pump

What are the benefits of water level sensors?

1, simple structure: no activity or elastic components, high reliability, no need for regular maintenance in the process of use. The operation is simple and convenient.

2, easy to install: when using, first connect one end of the wire correctly, and then put the other end of the water level probe into the solution to be tested.

3.测量范围可选：可测量1-200米内的水位，也可定制其他测量范围。

4、应用范围广：适用于高温高压、强腐蚀、高污染等介质的液位测量。建在河岸上的电子水位计可用于潮汐监测。

5、测量介质范围广：从水、油到高粘度膏体均可高精度测量，温度补偿范围广，不受被测介质起泡、沉积及电特性的影响。

6、使用寿命长：一般液位传感器在正常环境下可以使用4-5年，在恶劣环境下也可以使用2-3年。

7、功能强大：可直接连接数显表实时显示数值，也可连接多种控制器设置上下限，控制容器内的水量。

8、测量准确：内置优质传感器，灵敏度高，响应速度快，准确反映流量或静态液位的细微变化，测量精度高。

超声波液位传感器-水位监测系统-水位计

超声波液位传感器是根据超声波原理研制的一种测距仪器。它利用发射的声波脉冲在接收端测量时间来计算距离。超声波液位计由ABS材料制成，重量轻，无需维护和现场校准，可与计算机、数据采集器或其他符合RS485标准的采集设备配合使用。
