Multi-Parameter Water Quality Analyzer in Smart Secondary Water Supply Pump Stations

Application Case of DABECO W770 Multi-Parameter Water Quality Analyzer

1. Application Background: Water Quality Challenges in Secondary Water Supply
As the “last mile” of urban water supply, secondary water supply systems directly impact residential drinking water safety. However, traditional pump stations face persistent challenges:

Delayed monitoring: Reliance on periodic manual sampling results in poor data timeliness and delayed detection of risks such as insufficient residual chlorine, microbial growth, or turbidity caused by pipeline contamination.

High maintenance workload: Frequent manual cleaning and calibration increase operation and maintenance costs.

Limited functionality: Conventional systems monitor only a few parameters and lack integrated management of flow rate and pressure, making them unsuitable for smart water management.

To address these issues, a city launched a smart pump station upgrade project aimed at real-time monitoring, automatic alarms, and intelligent operation & maintenance. The project selected the DABECO W770 Multi-Parameter Water Quality Analyzer as the core monitoring device.

2. Solution Overview: Why DABECO W770
The W770 was chosen for its accuracy, reliability, and intelligent integration—perfectly suited to secondary water supply applications:

Comprehensive parameter coverage: Simultaneous measurement of residual chlorine, turbidity, pH, conductivity, and temperature, compliant with Hygienic Standards for Secondary Water Supply Facilities (GB 17051-1997).

High-precision sensor configuration:

Residual chlorine sensor (0–5 mg/L, ±5%)

Digital pH sensor (0–14 pH, accuracy <0.1 pH)

Low-range turbidity sensor (0.001–100 NTU, ±2%)

Digital conductivity electrode (0–200.0 mS/cm)

Intelligent operation & maintenance: Automatic cleaning, fault diagnostics, and over-limit alarms significantly reduce manual intervention. With a self-cleaning design, key components offer a service life of up to 3 years.
