System introduction
The QMS water quality online monitoring system is used for comprehensive remote monitoring and management of water quality by advanced intelligent water quality sensor, wireless transmission system, wireless communication, early warning system and intelligent management system. Plenty of historical data can be saved and analyzed to guide production and management, ensuring high productivity in aquaculture and increment, improving the quality of the crops grown and avoiding the environmental problems arising from water pollution.
System features
● Data monitoring: The water quality monitoring system is capable of online real-time monitoring of five general parameters of water quality by the sensor equipment (temperature, turbidity, pH value, conductivity and dissolved oxygen), permanganate index, ammonia nitrogen, various water quality ions, total phosphorus, total nitrogen and riverway flow.
● Data transmission: The online water quality monitoring technology can be used to upload the data acquired by the monitoring point to the client within a very short period of time with data promptness and effectiveness ensured. Compared to traditional manual sampling monitoring, it simplifies the bureaucratic procedure and saves the monitoring time.
● Monitoring and early warning: The user can set the security domain of the parameters monitored by the system platform. Once the water quality parameter in a place monitored by the front-end sensor exceeds the security domain, the system will send the alarm information to notify the user for timely treatment and ensuring the water quality of the impounding reservoir and reservoir is good.
● Data analysis: As for the water quality monitoring system, the monitoring period can be set with automatic acquisition, but no manual care. The system automatically generates the data sheet and the user can intuitively understand the water quality changes. The acquired data can be saved, and the historical data can be viewed at any time and used for analysis to sum up the experience for user's aquaculture and crop planting and guide management.

System application
The QMS water online monitoring system is used to monitor and measure the types of pollutants in the water body and concentrations and variation trends of various pollutants and evaluate the water quality. Its monitoring scope is wide, including natural water not polluted and having been polluted (river, lake, sea and underground water) and various industrial water drainages. It's widely used for online monitoring of plant sewage discharge in the industries (such as electric power, chemical engineering, printing and dyeing, papermaking and lithium battery new energy) and online monitoring of water quality and water samples for government water management, fishery management, aquaculture farmer, farmer households, agricultural cooperative and home farm.
