What is Ultrasonic liquid level sensor

Ultrasonic liquid level sensor detects the liquid level according to the principle of acoustic reflection. The biggest advantage is that it can detect the change of liquid level in real time, which is impossible for the other two non-contact liquid level sensors. Because the ultrasonic sensor can convert the water level into data and display it on the display board, the user can clearly know the real-time remaining water volume. The accuracy of ultrasonic liquid level sensor can reach ± 2mm, with high accuracy, which can detect the liquid level very accurately.

Because of the large volume of the ultrasonic sensor, there are requirements for the measuring range and the size of the measured liquid container. The container is too small to detect, so it is mostly used in the industrial field,. For example, the internal water tank of small household appliances such as coffee maker and water dispenser is not suitable for using ultrasonic liquid level sensor. And the price of ultrasonic liquid level sensor is high. When considering cost control, ultrasonic is not suitable for this kind of small household appliances.

The What is Capacitive Liquid Level Sensor

The capacitive liquid level sensor can detect the liquid level by sticking it on the container, so the installation process is simple. Capacitive liquid level sensors are mostly used in the field of household appliances, because the positioning is because the sensor has the characteristics of small volume and low price. If the capacitive liquid level sensor is installed on the body, the container can move freely.

The disadvantage of capacitive liquid level sensor is that it can only be used on non-metallic containers and can not detect liquids with low conductivity, such as diesel and gasoline. It is also unable to detect high-temperature liquid, which will cause sensor failure.

What is separated photoelectric liquid level sensor

The structure of the separated photoelectric liquid level sensor is to design the reflected light chasing part on the water tank, and the sensor does not directly contact the liquid, so as to realize non-contact detection. The separated photoelectric liquid level sensor has all the characteristics of photoelectric sensor. It is resistant to high temperature, high pressure and corrosion. It has high liquid level control accuracy and can control the liquid level within 1mm. The separated liquid level sensor also adopts resin sealing treatment for all internal components, and there are no moving parts inside, so it has high reliability. Because of the characteristics of small volume, high precision and high reliability, the separated photoelectric liquid level sensor is also commonly used in the field of household appliances and medical industry.
