DXmic Pro is the latest generation Digital Ground Microphone Water Leak Detection Equipment to precisely Localize the Position of a Leak in Buried Water Pipes.
Based on a highly sensitive piezo electric elephant foot ground microphone with an advanced touchscreen controller for identifying leaks in buried water pipes of different materials & depths, The DXmic Pro is used to listen for & pinpoint water leaks in in all types of water pipe networks under pressure, such as metallic and non-metallic water pipe networks, in both the main lines and branches of metro & industrial environment, for water pipes upto 600mm in diameter & which are being used at ≥ 1 bar pressure, allowing the operator to detect leaks in pipes buried upto 5 meter * depth below ground (* depending on pipe pressure, pipe material & condition).
DXmic Pro incorporates a wide variety of features including Auto filtering and frequency with display, to help pinpoint a leak position.
DXmic Pro further records leak noise, including the ability to replay recording, allowing the operator to validate leak located or additionally share with the leak expert within the team for validating prior digging for repair, and additionally allowing create an archive of leak sounds for reference.
The DXmic Pro is used together with DXmic Pro App to retrieve and share data and audio recordings. The App also enables to collect location information from the mobile device to complement measurements and sound recordings.
DXmic Pro App allows the user to share measurement data and recordings via email or using the HWM cloud based web portal DataGate.
The DXmic Pro is provided with sensors & accessories for use on smooth & gravely surfaces. In addition, an electronic listening stick for use on soft soil & for direct contact with pipes.

The system allows users to:
Focus on specific leak frequencies
Filter out traffic and background noise
It uses adjustable frequency filtering (typically ~1 Hz to several kHz range depending on mode).
DXmic Pro uses a high-sensitivity ground microphone (acoustic sensor) to detect sound waves generated by water leaks under pressure.
It includes High-sensitivity piezoelectric ground microphone
Yes, interchangeable ground interfaces allow use on: Concrete, Asphalt and Soil
Yes, depending on conditions: Typically up to ~5 meters depth
(affected by pipe material, pressure, and soil)
Typically up to ~25 hours continuous operation
Minimum recommended pressure: ~1 bar (absolute minimum)
Optimal working pressure: 2–6 bar (ideal range)
Yes, pipe material plays a critical role in how effectively leak sounds travel and are detected.
• Metal pipes (CI, DI, Steel):
Leak detection is easier because sound waves travel efficiently through rigid materials, allowing clear signal transmission over longer distances.
• Plastic pipes (PVC, HDPE):
Leak detection is more challenging because these materials absorb and dampen sound vibrations, reducing signal strength.
Yes, DXmic Pro is designed to handle difficult conditions like plastic pipelines.
It uses advanced frequency filtering and digital signal processing (DSP) to:
• Isolate weak leak signals
• Filter out background noise
• Enhance detection accuracy in sound-dampening materials
Yes, it can integrate with Mobile apps for:
• Data sharing
• GPS tagging
• Reporting
DXmic Pro is designed for field conditions and typically features:
IP65 (or similar industrial protection rating, depending on configuration)
5.0 inch TFT LCD Color Touchscreen
DXmic Pro is a lightweight handheld system, typically:
~2–4 kg (complete kit depending on accessories)
“DXmic Pro App” (Android & iOS)
Yes, the DXmic Pro App allows:
Sharing via email and Uploading to HWM DataGate cloud platform
Enables:
• Centralized data management
• Team collaboration
• Reporting
Data is shown as:
Bar graph representation of sound levels
Features include:
• Zoom in/out
• Scroll through measurements
• Select and analyze specific data points
HWM DataGate is a Cloud-based data management platform
Used for:
• Storing measurement data
• Managing multiple sites
• Sharing reports
DXmic Pro provides two main operating modes:
1. Survey Mode
2. Minimum Level Profiling (MLP) Mode
Survey Mode is used for:
• General leak detection and quick scanning
• Move along pipeline
• Listen to leak sounds
• Identify probable leak zones
Best for:
• Initial detection
• Large area surveys
MLP mode is an advanced leak pinpointing method where measurements are taken at regular intervals along the pipe route
Each point records:
• Noise level
• Acoustic intensity
Measurements are displayed as Bars in a histogram graph
DXmic Pro can store up to 100 measurements
Benefit:
• Covers long pipeline sections
• Enables detailed profiling
Yes, in MLP mode: Up to 2 minutes of audio recording per sample
