Water Level Sensor

Water level sensors, often known as the level sensors, are used to detect the level of substances that can flow. The water level sensor is restricted to check the level of water. Though it may also be used to check the level of other fluids that can flow, including the slurries, granular materials, and also powders, you will need a water level sensor when you need to check the level measurements inside a container or even a river or a lake. It’s a simple way to determine the number of materials that are found within a closed container or even the water flow in an open channel.

Water Level Sensor

There are many types of water level sensors that you can choose from the market! They all do what every water level sensor should do. Notably, the primary water level sensors can be used to identify that point at which a liquid falls or rises above the maximum. They have unique features that make the water sensing to be possible. Some will use a magnetic float that can rise or fall with a liquid in a container. The liquid rises with a magnet until a specific point where a magnetic reed switch is activated.

A water level sensors exist in a myriad of types. They can come in several variations, including the ultrasonic sensors, the bubblers, the float sensors, and pressure transducers. All these are the options that you can expect a water level sensor to be! Many forms may be available, but they still do the same.

If you intend to acquire one of the best water level sensors, then you can always choose the best from the best-selling platforms! It will be wise to check the price, the features, and more so what the buyers are saying about the water level sensor! A cost-effective water level sensor will be an excellent investment!

Key Features

  • ✅ The CQRobot non-contact liquid level sensor realizes non-contact detection of the liquid level in a closed container. It adopts advanced signal processing technology and high-speed signal processing chip, breaking through the influence of container wall thickness. It is simple to install and easy to use, and can detect the level of various toxic substances, strong acids, strong alkalis and various liquids in high-pressure airtight containers.
  • ✅ The principle is to use the inductive capacitance of water to detect whether there is liquid. When there is no liquid close to the sensor, the sensor has a certain static capacitance to the ground due to the existence of distributed capacitance on the sensor. When the liquid level slowly rises and approaches In the case of an inductor, the parasitic capacitance of the liquid will be coupled to this static capacitance, making the final capacitance value of the inductor larger.
  • ✅ The changed capacitance signal is then input to the control IC for signal conversion, which converts the changed capacitance into a change of a certain electrical signal, and then a certain algorithm is used to detect and judge the degree of this change. When the change exceeds a certain amount It is considered that the liquid level has reached the sensing point when the threshold is reached.
  • ✅ High stability, high sensitivity, strong interference ability, no external electromagnetic interference, special treatment for power frequency interference and common mode interference, strong compatibility, penetration of various non-metallic containers, such as plastic, glass, For ceramics and other containers, the sensing distance can reach more than 12mm; liquid, powder, and particulate matter can be detected.
  • ✅ The sensor comes with 2 DIP switches, the right DIP switch controls the output voltage (high level) of the signal terminal (green line); when the DIP switch is dialed up, the high level is 5V; when the DIP switch is facing When dialing down, the high level is 3.3V. Compatible with Arduino, Raspberry Pi and Other Motherboards.
