Pipe Network Water Quality Monitor: Multi-Parameter Self Cleaning

As refined water environment governance requirements keep rising, in-situ online water quality monitoring equipment must meet higher standards: multi-parameter measurement, long-term stable operation and minimized manual maintenance. Integrating multi-parameter detection, intelligent self-cleaning and digital signal transmission, the multi-parameter self-cleaning water quality monitor delivers high-performance solutions for diverse water environment monitoring applications.

After traditional online water quality sensors are submerged for a period, algae, biofilms and suspended sludge adhere to probe surfaces and gradually cause measurement errors. Frequent manual cleaning and calibration become routine maintenance work. Equipped with an intelligent automatic cleaning unit, this monitor allows customized cleaning intervals and cycles according to site water conditions. It regularly flushes the probe to restrain microbial adhesion, reduce contamination interference on readings, cut manual workload and lower long-term project O&M costs.

With integrated compact design, the monitor measures up to 8 water quality parameters simultaneously. Users can flexibly select digital sensors for dissolved oxygen, COD, pH, ORP, conductivity, ammonia nitrogen and turbidity, with temperature monitored synchronously. All sensors output digital signals via RS‑485 bus and standard Modbus/RTU protocol for strong anti-interference performance. The device can connect directly to remote data acquisition platforms to build a complete online water quality monitoring system for real-time data upload, storage and access.

Quick-plug waterproof connectors enable easy assembly and disassembly for simple, efficient sensor inspection and replacement. The front sensor protective cover balances protection and water permeability. Its slotted structure blocks large particles and aquatic organisms from damaging probes without obstructing water flow to guarantee measurement accuracy. The sensors offer reliable performance with multiple optional ranges, suitable for clean water, sewage and other water conditions.

Powered by 12VDC with ultra-low power consumption of only 5W. A 5m cable is supplied as standard; extended cables can be customized for different installation distances. Widely used in river surface water monitoring, industrial wastewater discharge monitoring, sewage treatment process control and aquaculture water monitoring. One unit replaces multiple standalone water meters, simplifying on-site wiring and reducing project construction costs.

During the development of smart water environment infrastructure, the monitor provides consistent, credible water quality data thanks to its multi-parameter integration, intelligent self-cleaning, stable communication and low-maintenance features. It supports real-time water condition supervision and advances digital transformation of water environment governance.
