Name：Online Intelligent Water Corrosion Rate Monitor
Model：ERUN-SZ4-A-N7
Parameter：corrosion rate
ERUN-SZ4-A-N7 on-line intelligent water quality corrosion rate monitoring, its core role is to real-time monitoring and assessment of water quality on pipelines, equipment and other materials corrosion impact, so as to protect the safety of water quality and the integrity of infrastructure. Through real-time monitoring of water corrosion rate for the prevention of equipment corrosion, water safety and optimisation of maintenance management to provide a scientific basis.
Water supply system: monitoring the corrosion of water quality in urban water supply pipelines, preventing pipeline aging, leakage, and ensuring the safety of drinking water.
Industrial circulating water system: in the circulating water system of chemical industry, electric power, metallurgy and other industries, it monitors the corrosion rate of water quality on equipment materials, optimises water quality management and improves the service life of equipment.
Marine engineering: applied to harbours, offshore platforms and other marine engineering facilities, monitoring the corrosion of seawater on metal structures to ensure the safety of engineering structures.
Oil and gas pipelines: monitor the corrosive impact of water quality (such as groundwater, rainwater, etc.) on pipelines in oil and gas transmission pipelines, prevent pipeline leakage, and ensure the safety of energy transport.
Water conservancy project: in reservoirs, dams and other water conservancy facilities, monitor the corrosion of water on the materials of water conservancy facilities, and provide data support for the maintenance of facilities.
