Multi parameter monitoring system for manholes
GNST-226GWWS monitoring of manhole liquid level is an important means of warning urban waterlogging and protecting urban water level safety. The waterproof multi parameter water quality measurement and control terminal can not only monitor the liquid level, but also expand parameters such as pH, conductivity, dissolved oxygen, ammonia nitrogen, COD, turbidity, suspended solids, etc. It can monitor the water quality status of urban drainage pipelines and manholes in real time and assist relevant departments of municipal and sewage treatment plants in effectively determining excessive discharge outlets. The battery and data collection transmission are integrated with waterproof design, and the battery is easy to replace and suitable for easy operation and maintenance. Monitor the micro power consumption and multifunctionality of the body, providing intelligent management for urban drainage.
