Introduction of water quality sensors


Water sensors are devices used to detect water levels in various applications. Water sensors can come in many variants including ultrasonic sensors, pressure sensors, bubblers and float sensors.

working method

Ultrasonic sensors work by transmitting sound waves that reflect off the surface of the liquid and are picked up by the sensor. The sensor measures the time interval between the transmitted signal and the received signal, which is then converted into a distance measurement by means of electronic circuitry within the sensor to measure the liquid level.

Floating sensors work by turning a pulley or spring-loaded shaft to change the resistance of the potentiometer inside the sensor. Bubbler sensors, on the other hand, measure water level by sensing the pressure of a submerged aerated tube with an opening at the bottom. When the water level is high, there is more static pressure at the end of the pipe, so more air pressure is required to fill the pipe.

Water quality sensors are used in nuclear power plants, automobiles to measure the amount of gasoline remaining in fuel tanks, engine oil, cooling water, and brake/power steering fluid.

Industrial applications for water level sensors include water level sensing in transportation and storage tanks as well as water treatment tanks. Manufactures different types of level gauges for use in municipal areas as well as in the food and beverage industry.

Water quality sensors make a difference

With the attention paid to environmental protection, water pollution is becoming a global problem. In order to monitor various pollutants in water, water quality sensor has become one of the essential tools. Water quality sensor is a kind of equipment that can detect the concentration of various chemical substances and physical parameters in the water body. It can monitor the water quality in real time and carry out early warning and management of water pollution.

Water quality sensor is mainly composed of sensor and data acquisition system. Sensor is the core part of water quality sensor. Water quality parameters can be detected by optical, electrochemical, electronic and other technical means. Different types of sensors can detect different water quality parameters. Such as temperature, PH, dissolved oxygen, turbidity, conductivity, ammonia nitrogen, total phosphorus, total nitrogen, etc. The data acquisition system digitizes the signal collected by the sensor. Transfer to the data processing unit for data processing and analysis.

Water quality sensors make a big difference

Water quality sensors have a wide range of applications. For example, in drinking water treatment, water quality sensors can be used to detect harmful substances in water to ensure the safety of drinking water. In aquaculture, water quality sensors can be used to monitor parameters such as oxygen and ammonia nitrogen in water to ensure the stability of aquaculture environment and the healthy growth of fish. In sewage treatment, water quality sensor can help to monitor the treatment effect, so as to achieve better water purification effect.

At present, water quality sensor technology has been very mature. There are various types of water quality sensors on the market. Such as portable water quality sensor, online water quality sensor, mobile water quality sensor, etc. At the same time, with the development of Internet of Things and cloud computing technology. Water quality sensors are gradually combined with intelligence and automation to realize remote monitoring and control.

Advantages of multi-parameter water quality monitoring stations

Multi-parameter water quality monitoring station is an important water quality monitoring equipment, which can meet the needs of various water quality monitoring. It has the characteristics of high precision, comprehensiveness and good stability, which can realize the real-time monitoring and control of water quality parameters.
