AML921 Downhole Digital Television for Groundwater Monitoring Wells
- “Top-Down + 360° Surround View” Dual-Camera System
The core technological breakthrough of the AML921 downhole digital television lies in its innovative “top-down + 360° surround view” dual-camera system.
The equipment integrates two sets of high-performance imaging units:
Top-down camera: Precisely locates sediments, fallen objects, and abnormal accumulations at the bottom of the well;
360° surround view camera: Scans the well wall structure from all angles, achieving three-dimensional observation.
Unlike the generic design of traditional imported equipment, the AML921 features a redesigned and optimized probe structure, enabling clear imaging of even minute impurities and deposits. It maintains stable imaging even in highly turbid water at 80 NTU, accurately identifying the thickness of green algae deposits down to the millimeter level, effectively solving the industry pain points of traditional analog equipment, such as blurry images and reliance on on-site expert interpretation.
- High-Strength Structure and Deep Well Adaptability
The AML921 features an industrial-grade structural design, providing excellent environmental adaptability:
316 Stainless Steel Probe Housing
IP68 High-Level Protection
300-Meter Standard Pressure-Resistant Sealing Design
Maximum Working Depth Customizable to 500 Meters
The equipment can operate stably in high-pressure, deep well, and complex geological environments, maintaining complete sealing and reliable imaging even under extreme water pressure conditions.
- Digital Imaging and Automatic Data Output
The AML921 represents a breakthrough upgrade from “observation” to “data-driven analysis.”
The equipment supports:
High-definition digital video recording
Automatic data export
Automatic generation of image evaluation reports with depth scales
Users can remotely conduct well condition observations and professional assessments without on-site supervision, significantly improving work efficiency and decision-making speed.
- Verification of Practical Application Effects of Groundwater Monitoring Wells
In multiple groundwater monitoring projects, the AML921 demonstrated significant application value:
An environmental protection project in Shandong Province:
Of 30 monitoring wells, two showed continuous anomalies. Using the AML921, within just 10 minutes of testing, silt blockage was detected in the screen pipes at 14 meters and 35 meters. After precise well cleaning, the two “near-failure” monitoring wells were successfully restored to function, extending their service life by more than 5 years.
A chemical industrial park project:
The AML921 quickly identified well pipe cracks and silt deposition problems, and timely repairs effectively prevented potential pollutant leakage risks.
- Building a Complete Quality Chain for Groundwater Monitoring
The AML921 is not only a downhole imaging device, but also a crucial link in the Emory groundwater monitoring system.
After equipment such as AML913, AML916, and AML919 complete water level measurement, six-parameter analysis, and precise sampling, AML921 is responsible for conducting a “visual physical examination” of the monitoring well, comprehensively assessing the health status of the well body, and forming a complete closed-loop guarantee for data quality.
