Practical Guides for Water Quality Monitoring

Selecting the right water quality monitoring system requires more than choosing an individual instrument. The application, water conditions, monitoring parameters, installation environment, communication method, and data requirements all need to be considered.
Our monitoring guides provide practical information to help you understand these factors and make informed decisions when planning an online water quality monitoring system.

Water Quality Monitoring Topics

Water Quality Parameters

Understand commonly monitored parameters such as DO, pH, ammonia nitrogen, COD, turbidity, conductivity, salinity, and temperature.

Monitoring Equipment

Learn about online water quality analyzers, multi-parameter monitors, sensors, monitoring stations, and data acquisition equipment.

System Configuration

Understand how sensors, monitoring equipment, data acquisition, communication, and remote platforms work together.

Parameter Selection

Learn how monitoring parameters can be selected according to water type, application, monitoring objectives, and monitoring points.

Online Monitoring

Understand the basic principles and advantages of continuous online water quality monitoring.

Remote Monitoring & IoT

Learn how 4G, LoRa, Internet connectivity, data acquisition, and IoT platforms can support remote water quality monitoring.

Understanding Water Quality Monitoring

Water quality monitoring involves measuring selected physical, chemical, and environmental indicators to understand changes in water conditions.
The appropriate approach depends on the water type and monitoring objectives.
Single-parameter measurement · Multi-parameter monitoring · Online continuous monitoring · Outdoor monitoring stations · Remote data acquisition · Cloud or IoT-based monitoring
  • Depending on the application, monitoring may involve:

How to Select the Right Water Quality Parameters

Parameter selection should start with the application and monitoring objective, rather than the equipment itself.

01. Identify the Water Application

Examples include:

02. Define the Monitoring Objective

Determine whether you need:

03. Select the Required Parameters

Typical parameters may include:

04. Determine the Monitoring Configuration

Consider: Process monitoring · Environmental monitoring · Water quality assessment · Early warning · Treatment monitoring · Continuous data collection · Number of monitoring points · Sensor configuration · Installation environment · Communication method · Power supply · Data transmission · Remote monitoring requirements

An online monitoring system continuously collects water quality data from the monitoring point. The data can be processed, transmitted, stored, and displayed through an integrated monitoring architecture.
Depending on the configuration, users can access real-time measurements, historical data, trends, alarms, and device information remotely.

Online Monitoring vs. Manual Measurement

Online monitoring and manual measurement can serve different purposes. For applications requiring continuous observation, early warning, or remote management, an online monitoring system can provide a more continuous source of measurement data.

How to Choose Water Quality Monitoring Equipment

Different monitoring requirements call for different types of equipment.

Online Water Quality Analyzers

For continuous online analysis of applicable chemical and water quality parameters.

Multi-Parameter Water Quality Monitors

For integrating multiple sensors into one centralized monitoring system.

Water Quality Sensors

For direct measurement of individual water quality parameters.

Water Quality Monitoring Stations

For outdoor and distributed monitoring applications.

Data Loggers & Telemetry

For data acquisition, transmission, remote monitoring, and system connectivity.

Typical Monitoring Configurations

For continuous monitoring of pond and aquaculture water conditions.

Aquaculture

DO + pH + Temperature + Ammonia Nitrogen + Nitrite Nitrogen

Wastewater

COD + Ammonia Nitrogen + TN + TP + pH + Turbidity

River & Lake

DO + pH + Temperature + Turbidity + Conductivity

Water Treatment

pH + Turbidity + Conductivity + Residual Chlorine

Industrial Water

pH + Conductivity + Temperature + ORP

From Field Measurement to Remote Data

Online monitoring systems can connect field measurement equipment with remote data platforms.

Measurement

Sensors and analyzers collect water quality data.

Acquisition

Data acquisition equipment collects and organizes measurement data.

Communication

Data can be transmitted through available communication methods such as 4G, LoRa, or Internet connectivity.

Platform

The monitoring platform can provide data visualization, historical records, alarms, and device management.

Access

Users can access monitoring information through PC, web, or mobile applications depending on the system configuration.

Consider the Monitoring Environment

The installation environment can affect equipment selection and system configuration.

Indoor Monitoring

Suitable for treatment plants, laboratories, equipment rooms, and controlled monitoring environments.

Outdoor Monitoring

Requires appropriate protection, installation structure, power supply, and communication configuration.

Floating Monitoring

Suitable for selected rivers, lakes, reservoirs, aquaculture areas, and ecological water applications.

Distributed Monitoring

Multiple monitoring points can be connected to a centralized platform for remote data management.

Frequently Asked Questions

How do I know which water quality parameters I need?

Parameter selection depends on the water type, application, monitoring objective, and monitoring location. Common parameters include DO, pH, ammonia nitrogen, COD, turbidity, conductivity, salinity, and temperature.

A single-parameter system may be suitable when only one indicator needs to be monitored. A multi-parameter system can be more appropriate when several water quality indicators need to be monitored at the same location.

Consider the required parameters, measurement method, monitoring environment, installation method, communication, power supply, number of monitoring points, and data management requirements.

Yes. Depending on the system configuration, data can be transmitted through 4G, LoRa, Internet, or other available communication methods and accessed through a remote platform.

Yes. Monitoring parameters, sensors, installation, communication, power supply, and data management can be configured according to project requirements.
