Release time：
2025-10-25
Water withdrawal measurement is the cornerstone of water resource management. By accurately measuring water extraction and monitoring usage dynamics in real time, it provides critical data support for industrial production, agricultural irrigation, urban water supply, and ecological environmental protection. Drawing on the technological practices of companies such as Xiamen Haichuan Runze IoT Technology Co., Ltd., the application of water withdrawal measurement equipment has expanded into multiple key sectors, driving water resource management toward greater precision and intelligence.
I. Agricultural Irrigation: The Foundation of Water Conservation and Efficiency
Agricultural irrigation is the largest consumer of water resources, accounting for over 60% of the nation's total water usage. Traditional irrigation methods often involve repeated water withdrawals and lack accurate measurement, leading to significant water waste. The introduction of water withdrawal measurement equipment enables real-time monitoring of irrigation water use, regulating irrigation timing and frequency, and promoting efficient water utilization.
Technical Support:
Smart Meter and Water Meter Integration: The "dual-control of well and electricity" system uses smart electricity meters to record pump operation time, combined with water meters to accurately calculate irrigation water usage per session.
Ultrasonic Flow Meters: These utilize the difference in ultrasonic wave propagation speed in fluids to enable non-contact flow measurement, avoiding interference from water quality or pressure.
Remote Monitoring Platforms: Real-time transmission of withdrawal data to management terminals allows operators to remotely control irrigation equipment and optimize water usage plans via smartphones or computers.
Application Value:
Precision Irrigation: Dynamically adjusts irrigation volume based on crop water needs, reducing soil salinization caused by over-irrigation.
Water Conservation and Emission Reduction: Feedback from measurement data guides farmers to adopt water-saving technologies such as drip and sprinkler irrigation, reducing agriculture’s share of water use.
Policy Implementation: Provides data support for agricultural water pricing reforms and promotes the implementation of policies based on "total control and quota management."
II. Industrial Production: A Core Tool for Water Management
Industrial water use accounts for over 20% of the nation’s total water consumption, covering high water-consuming sectors such as chemicals, textiles, paper, and steel. Traditional industrial water management relies on manual statistics, which are often delayed and inaccurate. The widespread adoption of water withdrawal measurement equipment enables real-time monitoring of enterprise water intake and analysis of usage patterns, helping companies optimize production processes and reduce water costs.
Technical Support:
Electromagnetic Flow Meters: Based on Faraday’s law of electromagnetic induction, these are suitable for measuring conductive liquids, offering high accuracy and strong stability.
Turbine Flow Meters: These measure flow by correlating turbine rotation speed with fluid velocity, ideal for small to medium flow applications such as cooling water systems.
IoT-Integrated Systems: Combine flow meters with sensors, data collectors, and cloud platforms to enable automatic data upload and anomaly alerts.
Application Value:
Cost Control: Identifies water waste points—such as cooling water leaks or excessive equipment cleaning—helping to reduce production costs.
Regulatory Compliance: Meets environmental authorities’ requirements for industrial water permits and usage plans, avoiding penalties for over-extraction.
Water Recycling: Combined with water quality monitoring equipment, it helps assess the potential for industrial wastewater reuse and promotes the development of reclaimed water systems.
III. Urban Water Supply: Ensuring Stable Supply
Urban water supply systems serve residential life, public facilities, and commercial services, accounting for over 10% of national water usage. Traditional urban water management relies on manual meter reading, which is prone to delays and missed readings. The intelligent upgrade of water withdrawal measurement equipment, through real-time monitoring of pipeline flow and pressure, ensures water supply safety and improves service quality.
Technical Support:
Smart Water Meters: Utilize electronic remote-reading technology for automatic data collection and transmission, supporting tiered water pricing.
Pressure Sensors: Monitor pressure changes in pipelines to detect anomalies such as bursts or leaks, reducing unplanned water outages.
Big Data Analytics Platforms: Integrate data from water withdrawal measurement, water quality monitoring, and user complaints to optimize pipeline operations.
Application Value:
Accurate Billing: Smart meters charge based on actual usage, avoiding measurement errors caused by mismatched meter sizes and flow rates.
Leakage Control: Combined with pressure monitoring, it helps locate pipeline leaks and reduce urban water loss.
Emergency Response: Real-time monitoring of water usage from fire hydrants and public sprinklers ensures emergency water availability.
IV. Ecological Environment: The “Eyes” of Water Resource Protection
Rivers, lakes, and reservoirs are vital components of ecosystems, and changes in their water levels directly affect environmental quality. Water withdrawal measurement equipment monitors inflow and ecological water replenishment, providing data support for water resource protection and pollution control.
Technical Support:
Float-Type Water Level Meters: Use a float connected to an encoder to continuously measure water levels, commonly used in reservoir monitoring.
Radar Flow Meters: Use radar wave reflection for non-contact flow measurement in rivers, suitable for sediment-laden waters.
Satellite Remote Sensing: Combined with ground-based measurement data to calibrate hydrological models, improving large-scale water monitoring accuracy.
Application Value:
Ecological Flow Protection: Determines minimum ecological water requirements for rivers to prevent flow interruption due to over-extraction.
Pollution Source Tracing: Correlates withdrawal data with pollutant concentrations to identify pollution sources.
Ecological Restoration: Provides water volume data for wetland replenishment and lake regulation projects, supporting ecosystem recovery.
V. Special Applications: Extended Innovation of Technology
Beyond traditional fields, water withdrawal measurement equipment is expanding into special scenarios, driving the development of high-precision and highly adaptable technologies.
1. Groundwater Management:
In regions such as the North China Plain, where groundwater is over-extracted, the "electricity-to-water" method is used. By analyzing the relationship between pump electricity consumption and water extraction, indirect calculation of groundwater usage is achieved. This approach addresses the challenges of high cost and difficult installation of traditional meters, supporting groundwater conservation efforts.
2. Marine Water Intake:
In coastal facilities like nuclear power plants and chemical factories, corrosion-resistant flow meters combined with salinity sensors monitor seawater intake volume and salinity changes in real time, preventing equipment scaling and corrosion.
3. Polar Research:
In extreme environments such as Antarctic research stations, low-temperature flow meters with heating systems prevent freezing, ensuring accurate water measurement for scientific missions.
