01 · 2021 · Liangshan, Sichuan, China

Water-plant inlet and outlet chlorine monitoring

Project background: A town water plant in Liangshan supplies production and domestic water and required continuous online measurements to strengthen water-supply safety and process oversight.
Implementation: In June 2021, flow measurement and online analyzers were installed at inlet and outlet points so operators could identify water-quality risks and review disinfection performance continuously.
Monitored parameters: Free chlorinepHSuspended solidsChlorine dioxideFlow
Chlorine configuration: PDCL-600 was documented for online free-chlorine measurement alongside pH, suspended-solids and chlorine-dioxide monitoring.
Project role: The system improved early warning at key process points and provided continuous data for plant water-safety management.

English-screen chlorine controller and black sensor installed on a secondary water-supply pipeline

02 · 2022 · Wuhan, Hubei, China

Secondary water-supply residual-chlorine monitoring

Project background: Secondary water-supply facilities form the final link between the municipal network and residents. Aging or inefficient equipment can reduce the disinfectant residual and increase water-quality risk.
Implementation: In September 2022, an online analyzer was installed to track free chlorine in the secondary-supply pipeline continuously and provide timely visibility of disinfectant residual.
Monitored parameters: Free chlorinePipeline flow-cell conditions4–20 mA signal
Chlorine configuration: PDCL-500M was documented as the online free-chlorine analyzer for the pipeline installation.
Project role: Continuous measurement supported safer secondary supply by showing whether an effective chlorine residual was maintained through the final distribution stage.

Automation cabinet, sample line and touchscreen water-quality unit in an integrated monitoring room

03 · 2023 · China

Integrated county water-supply monitoring platform

Project background: A county water-supply integration project upgraded water-plant automation and connected water-quality equipment to a central information-management platform.
Implementation: In April 2023, pipeline monitoring was installed to combine pH, turbidity, dissolved oxygen, conductivity and residual chlorine for routine inlet, outlet and distribution-water checks.
Monitored parameters: Free chlorinepHTurbidityDissolved oxygenConductivity
Chlorine configuration: PDCL-500M supplied the residual-chlorine measurement within the integrated distribution-water monitoring system.
Project role: The project improved visibility from the water plant to end users and supported safer, more reliable county-wide supply management.
