Solafact W320

Product Introduction

The Solafact – W320 Professional Dam Piping and Leakage Detection Instrument is a new device designed and manufactured based on the fundamental principles of the “flow field method.” It offers high precision, accuracy, and rapid detection of piping and leakage in the water intake and leakage channels of rivers and reservoirs. This instrument is suitable for detecting piping and leakage in various dam types, including earth dams, rock-fill dams, and concrete dams. Comprising a transmitter, receiver, and sensor, the Solafact – W320 works together to send signals, capture data, and detect changes in the flow field. Advanced technologies such as pseudo-random current signal transmission and reception, near-field source strengthening technology, high-resolution rapid detection of current density fields, and multi-component detection of current density fields enhance its capabilities.

During the flood season, the instrument quickly and accurately determines the specific location of piping and leakage, enabling timely and effective response measures, significantly reducing the resources needed for flood control and minimising losses to life and property. In the non-flood season, it can be used for the maintenance and management of dam structures in rivers and reservoirs, thereby protecting water resources. The Solafact – W320 is applicable for detecting various dam types and their foundations.

An embedded intelligent industrial control computer serves as the main platform, providing a user-friendly interface and the ability to connect to RTK (Real-Time Kinematic) systems and depth gauges for high-precision data collection and positioning.

Features
  • Adjustable Output Voltage: The instrument provides 5 adjustable voltage levels, which is particularly suitable for field work and practical applications.
  • Fully Digital Signal Acquisition and Processing Technology: Ensure the stability and reliability of data processing.
  • Real-time Curve Plotting: The ability to draw curves in real time allows for rapid anomaly analysis and positioning directly on site, and provides immediate feedback on any anomalies detected.
  • Data Storage and Tagging: Real-time data can be stored and marked, and later data processing can be performed to facilitate the submission of results.
Application Areas

The dam piping leakage detector was used for on-site operation demonstration. The actual on-site operation time was very short, including construction wiring and water surface measurement, a total of less than 3 hours. The task was completed quickly and accurately, with high precision and accuracy in detecting piping leakage, providing a scientific basis for flood control work.
