Water conservancy water

Water is the source of life, is an indispensable and precious natural resource for social and economic development.However, with the continuous deterioration of the world environment, the fresh water resources show a sharp decline, seriously hindering the development of the world economy.People can reuse the used water through sewage treatment, reclaimed water reuse and other ways to reduce the excessive exploitation of fresh water.Sewage treatment needs to control a series of parameters such as temperature, pressure, flow rate and liquid level, which will be used in our sewage treatment control system. The system integrates a series of products such as temperature sensor, pressure sensor, flow sensor and liquid level sensor for effective monitoring and control.

Therefore, the water treatment industry is getting more and more attention and is constantly promoted to carry out technological innovation and the development of the whole industry.Although China's environmental protection water treatment industry started relatively late, but with the continuous development of the economy and the government's attention is not increased, in recent years has been rapid development, and the future prospects are broad.


1. sewage treatment

The water and wastewater treatment industries are increasingly relying on pressure sensors to ensure reliable, reliable and high-performance systems.In water and wastewater treatment processes where reliability is critical, the use of pressure sensors can provide an important means of system protection and quality control.These devices can not only withstand extremely demanding conditions, such as extreme temperatures, mechanical shocks and vibrations, but also provide precision control.

Automatic control of liquid level is often encountered in water treatment engineering.Especially when the collecting pool is outdoors and the water treatment equipment is indoors, the sensor or its connecting line or contact point is exposed to the outdoor damp and causes loss of control, resulting in wrong action.General wastewater in the process of continuous treatment, often do not need to reach the highest level of the catchment tank to put into work, but the lower level is required to prevent the pump idling, especially some electrolytic treatment of wastewater equipment will be damaged due to water loss.

With the advent of products with excellent performance and affordable price, pressure sensors are bound to be widely used in various water and sewage treatment facilities.Some of the test data of these devices are excellent, such as pressure change response time as low as 1ms or even faster, accuracy nearly zero drift with time, and operating life of over 100 million cycles.These excellent performance and reliability are welcome in the water supply and water treatment industry for two reasons: ensuring plant safety critical accuracy and minimizing component maintenance and replacement in equipment that is not easily serviced.

Even in harsh or corrosive media such as seawater desalination plants or sludge treatment applications, pressure sensors can operate stably, and excellent vibration resistance enables them to be installed near pumps, which are ubiquitous in the water treatment industry.

2. Water resources and hydropower

The degree of automation is one of the important indicators to measure the level of modernization of hydropower plants. The computer monitoring system of hydropower plants is compared to the brain of the automation system, so the sensors are the eyes and ears of the computer monitoring system to complete process monitoring and control.Many stable and high-quality sensors and transmitters provided by hanga can adapt to all kinds of hydro-generator sets and auxiliary machinery systems of the plant, meet the requirements of monitoring the relevant physical quantities of each equipment and system of the hydropower plant, and provide help for the long-term, safe operation and protection of the hydropower plant.
