The water level sensor is a device that measures the liquid level in a fixed container that’s too high or too low. In accordance with the tactic of measuring the liquid level, it may be divided into two types: contact type and non-contact type. The enter type water level transmitter we call is a contact measurement, which converts the height of the liquid level into an electrical signal for output. It’s currently a widely used water level transmitter.
How does the water level sensor work?
The working precept of the water level sensor is that when it is put into a sure depth in the liquid to be measured, the pressure on the sensor’s front surface is transformed into the liquid level height. The calculation formula is Ρ=ρ.g.H+Po, in the formula P is the pressure on the liquid surface of the sensor, ρ is the density of the liquid to be measured, g is the local acceleration of gravity, Po is the atmospheric pressure on the liquid surface, and H is the depth at which the sensor drops into the liquid.
Where to use water level sensors?
The uses of water level sensors embody the next applications:
1. Water level measurement of pools and water tanks
2. Water level measurement of rivers and lakes
3. Marine level measurement
4. Level measurement of acid-base liquids
5. Oil level measurement of oil trucks and mailboxes
6. Swimming pool water level management
7. Tsunami warning and sea-level monitoring
8. Cooling tower water level management
9. Sewage pump level control
10. Remote monitoring of the liquid level
What are the benefits of water level sensors?
1. Simple structure: There are no movable or elastic parts, so the reliability is extraordinarily high, and there is no need for normal maintenance during use. The operation is simple and convenient.
2. Convenient installation: When utilizing, first connect one finish of the wire appropriately, after which put the opposite finish of the water level probe into the answer to be measured.
3. Ranges are optional: you possibly can measure the water level in the range of 1-200 meters, and other measurement ranges can also be customized.
4. Large range of applications: suitable for liquid level measurement of high temperature and high pressure, robust corrosion, high pollution, and other media.
5. Vast range of measuring medium: High-precision measurement can be carried out from the water, oil to paste with high viscosity, and wide-range temperature compensation will not be affected by the foaming, deposition, and electrical characteristics of the measured medium.
6. Long service life: Typically, the liquid level sensor can be utilized for four-5 years in a normal surroundings, and it may also be used for two-three years in a harsh environment.
7. Strong function: It may be directly connected to the digital display meter to display the value in real-time, or it may be connected to a variety of controllers and set the higher and lower limits to manage the water quantity in the container.
8. Accurate measurement: The constructed-in high-quality sensor has high sensitivity, fast response, and accurately reflects the subtle adjustments of the flowing or static liquid level, and the measurement accuracy is high.
9. Number of types: liquid level sensors have numerous structural designs equivalent to input type, straight rod type, flange type, thread type, inductive type, screw-in type, and float type. It could actually meet the measurement needs of all totally different places.
