What is a water level sensor?
A water level sensor 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:
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
9.Remote monitoring of liquid level
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. Measuring range optional: can measure the water level within 1-200 meters, can also customize other measuring range.
4. a wide range of applications: suitable for high temperature and high pressure, strong corrosion, high pollution and other media level measurement. An electronic water gauge built on the riverbank can be used for tide monitoring.
5. the measurement medium range is wide: from water, oil to high viscosity paste can be measured with high precision, and the temperature compensation range is wide, not affected by the foaming, deposition and electrical characteristics of the measured medium.
6. long service life: general liquid level sensor in normal environment can be used for 4-5 years, in harsh environment can also be used for 2-3 years.
7. powerful function: can be directly connected to the digital display table real-time display value, can also be connected to a variety of controllers to set the upper and lower limits to control the amount of water in the container.
Ultrasonic level sensor-water level monitoring system-water level meter
The ultrasonic level sensor is a distance measuring instrument developed based on the principle of ultrasonic waves. It uses the transmitted sound wave pulse to measure the time at the receiving end to calculate the distance. The ultrasonic level gauge is made of ABS material, is light in weight, does not require maintenance and on-site calibration, and can be used in conjunction with a computer, data collector or other RS485-compliant collection equipment.
1. One notable feature of ultrasonic level sensors is their non-contact measurement capability. Unlike traditional level sensors that require physical contact with the liquid or solid material, ultrasonic sensors can measure levels from a distance. This makes them ideal for applications where direct contact is not possible or where contact may contaminate the substance being measured.
2. Another key characteristic is their versatility. Ultrasonic level sensors can be used to measure levels in a wide range of liquids and solids, including water, chemicals, oils, and bulk materials. They can be employed in various industries such as wastewater treatment, industrial manufacturing, food and beverage, and storage tank monitoring.
3. Ultrasonic level sensors are also known for their high accuracy. They provide precise level measurements with minimal error, ensuring reliable monitoring and control of fluid levels. Additionally, these sensors are capable of measuring both short and long distances, making them suitable for applications where the depth or height of the substance being measured varies.
4. Furthermore, ultrasonic level sensors are easy to install and operate. They are typically compact and require minimal space for installation. Once installed, they can be integrated with control systems or monitoring devices, allowing for easy data collection and analysis.
