The working principle and application of water level sensor

1. What is the water level sensor?

The water level sensor is an instrument that can transform the water level parameter at the measured point into the corresponding power signal in real time.

 

2. Working principle of water level sensor

The water level sensor in the container will feel the water level signal to the controller, and the computer in the controller will compare the measured water level signal with the set signal to derive the deviation, then according to the nature of the deviation, the electric valve for water supply will be issued "open" and "close" instructions to ensure that the container reaches the set water level. After the water feeding procedure is completed, the computer in the temperature control section issues an "open" command to the electric valve supplying the heat medium, so the system starts to heat the water in the container. When the set temperature is reached. Only when the controller issues the command to close the valve, cut off the heat source, and the system enters the heat preservation state. The programming process ensures that the system does not reach the safe water level, the electric control valve of the heat source does not open the valve, thus avoiding the loss of heat and the occurrence of accidents.


3. What is the role of the water level sensor?

Take the fire fighting water tank for example, when filling water in the tank, you can set the upper and lower water level values. When the water is insufficient or exceeded, the water level sensor will issue an alarm, according to the alarm information data, and then the site regulation. It realizes wireless signal transmission and information interaction without manual inspection, which saves manpower and construction costs and helps users achieve timely and efficient supervision of the pipe network.

 

4. Application fields of water level sensor

Widely used in water plants, oil refineries, chemical plants, glass plants, sewage treatment plants, high-rise water supply systems, reservoirs, rivers, oceans, etc. for the measurement and control of supply pools, distribution pools, water treatment pools, wells, tanks, water tanks, oil wells, oil tanks, oil pools and static and dynamic liquid levels of various liquids.

The working principle of carbon dioxide detector

图片
The working principle of carbon dioxide detector The working principle of the CO2 detector is mainly based on the infrared light source absorption principle. The following is the detailed working mechanism: Infrared absorption principle: Carbon dioxide detectors detect carbon dioxide gas in the environment through the absorption properties of infrared light sources. Specifically, carbon dioxide molecules have absorption properties for infrared light of specific wavelengths, especially infrared light with a wavelength of approximately 4.26 microns (4260 nanometre ). Measuring chamber and light source: The gas to be measured is introduced into a measuring chamber with an infrared light source mounted at one end of the chamber and a filter and detector at the other end. The filter allows infrared light of a specific wavelength to pass through, while the detector measures the luminous flux through the chamber. Detector Measurement: The amount of light flux received by the detector depends...

Introduction of temperature and humidity data recorder A temperature and humidity data logger is a device used to monitor and record changes in temperature and humidity in the environment. It has an important role in many areas, such as: In the laboratory, it can ensure that the experiment is carried out under the appropriate temperature and humidity conditions to ensure the accuracy of the experimental results. In the storage place, it helps the management to monitor the temperature and humidity inside the warehouse to prevent the goods from getting damp or mildew. In the production workshop, the temperature and humidity of the production environment can be monitored to ensure the normal progress of the production process. Type of temperature and humidity data logger Digital temperature and humidity recorder Features: The temperature and humidity data in the environment is collected by the sensor and displayed in digital form. This type is more common, simple and intuitive operation,...

Weather Forecasting

图片
  The Importance of Weather Forecasting Weather forecasting has an extremely important impact on our daily lives, economic activities and social security. The following are some of the main aspects: 1. Prevention of natural disasters Weather forecasts can predict possible weather disasters in advance, such as heavy rain, typhoons, snowstorms, etc., so as to take appropriate precautions to reduce the loss of life and property.   2. Planning life and production activities People can understand the future weather changes through the forecast, reasonable planning of travel, tourism, outdoor activities, etc., to improve the convenience and safety of life. For agricultural production, weather forecasts can provide farmers with references for agricultural activities such as sowing, fertile  application, irrigation, etc., so as to improve the efficiency of agricultural production and yield.   3. Emergency response When emergencies occur, such as epidemics, earthquakes, etc.,...
