In the operation and maintenance management of groundwater at nuclear power plant sites, accurate measurement of groundwater flow velocity and direction constitutes the core foundational work for hydrological analysis, site assessment, and hazard prevention.

The conventional interwell tracer‑testing method has long been plagued by industry‑wide pain points, including lengthy turnaround times, significant data variability, and cumbersome operational procedures. , making it difficult to meet the high-precision, high-efficiency standards for nuclear power plant monitoring.

Customer Case Studies

Recently, Emory completed a groundwater flow survey project for a certain nuclear power plant operation and management company, in order to… AML920 The groundwater flow velocity and direction meter replaces traditional detection methods.

The nuclear power plant site originally had multiple sets of monitoring wells, including upstream ones. 2 Monitoring well, downstream 7-8 Monitoring well.

In the past, the plant site has long relied on the conventional tracer‑based detection method:

By injecting a tracer into an upstream well and monitoring the downstream well’s water concentration over an extended period, flow‑rate data can be estimated by correlating it with the travel time. However, this conventional approach… The drawbacks are pronounced: the overall surveying cycle is extremely lengthy, labor costs are high, and the process is heavily influenced by stratigraphic structure and well conditions. Data can only be estimated roughly, and its accuracy is insufficient to meet the stringent hydrological analysis requirements of nuclear power plants, posing a significant challenge for on-site hydrological monitoring.

The customer learned about Emory through industry videos. AML920 The groundwater flow velocity and direction meter, after extensive brand comparisons, technical assessments, and operational-condition consultations, was ultimately selected. AML920 The groundwater flow velocity and direction meter is conducting field survey work.

Precise and Clear Monitoring

AML920 Enables direct well‑site surveying and one‑click, precision data output. The device is equipped with a high‑definition overhead view, 360° The dual‑camera system provides real-time visualization of downhole conditions, clearly identifies wellbore screen openings, and precisely locks onto optimal monitoring locations.

Comes with a professional cable marked with meter increments, enabling precise determination of the probe’s underwater depth and compatibility with a wide range of complex well conditions.

Intelligent analysis system, stable and continuous

AML920 The groundwater flow velocity and direction meter is equipped with professional… Flow Pro The data analysis system intelligently adjusts image brightness, contrast, color saturation, and rotation angle, accurately capturing the trajectories of particles in water. Leveraging computer vision algorithms and three-dimensional vector analysis, it calculates in real time key parameters such as groundwater flow velocity, flow direction, and water temperature.

Device Default 5 High-frequency sampling at one sample per second, with support for customizable monitoring intervals, delivering continuous, stable, and reliable data.

Real-world case: Customer approval

The on-site construction process this time was efficient and standardized: upon arrival, the team first conducted a comprehensive inspection of the well conditions and surrounding environment, then lowered a probe into the water body and allowed it to remain undisturbed. 15 To 30 After the water quality has stabilized for a few minutes, initiate fully automatic monitoring.

Throughout the entire process, no reagents need to be added, and no cross-well observations are required; relying on the equipment’s intelligent algorithms, data are automatically collected, processed, and generated in multiple valid datasets.

Following the completion of the survey, Emery issued a professional monitoring report whose data were precise and aligned with the plant’s actual geological conditions, demonstrating a high degree of consistency with the client’s geological modeling results.

The customer highly commended the equipment’s performance, surveying efficiency, and data accuracy. One month after the project was commissioned, the customer formally submitted a procurement request, and the project has now successfully completed all acceptance procedures.

High-quality equipment is the foundation, and long-term service is the core. Project acceptance is not the end of the collaboration; it marks the beginning of ongoing support.

Going forward, Emery will continue to provide high-precision monitoring equipment and standardized on-site services, ensuring reliable groundwater monitoring for nuclear power, hydrology, environmental protection, and other projects, thereby supporting the industry’s transition toward smarter, more precise hydrological surveying.
