Water is used in a wide range of applications, and a variety of applications have arisen. One of them is the monitoring of water, and different applications, some can be in direct contact with the liquid to monitor the level, some require no contact with the liquid to achieve the protection of water quality. So what are the sensors suitable for non-contact liquid level monitoring?
Non-contact detection of liquid level sensors, photoelectric principle and capacitive principle, and ultrasonic principle.
Non-contact photoelectric level sensors, using optical principles, need to design prisms on the water tank (can contact us to cooperate with the design), you can realize the detection of liquid. Advantages include: high reliability, high accuracy, versatile installation, and less likely to harbor dirt.
Non-contact photoelectric level sensors can also be realized to detect whether the tank is in position or not.
Capacitive level sensor, because it is the capacitive principle, so for the tank material requirements, the requirement is non-metallic material. Secondly, the thickness of the tank will also affect the detection, so the wall thickness of the tank will also have requirements. The installation method is close to the outer wall of the water tank detection. Its advantages are easy to install and convenient to use. But compared with photoelectric level sensor, the accuracy will be low. Suitable for equipment that does not require high precision.
