Find The Leak Faster — Correlate, Listen, Pinpoint.
A modern overview of HWM acoustic leak detection: noise correlators, digital ground microphones and leak loggers that locate and confirm leaks on metallic and plastic mains. Use this page to understand the workflow, then open each product page for detailed specifications.
Patrol the network with acoustic noise loggers to flag leaking DMAs and sections.
02PinpointWalk the line with a ground microphone to find the loudest point on the surface.
03CorrelateFix the leak position between two sensors to within about one metre.
04ConfirmRecord acoustic evidence, mark the dig and repair with confidence — first time.
Start With The Field Problem.
Every tool here does one thing: turn leak noise into a confident dig location. The cards keep the overview short, while each product page carries the deeper specs and configuration notes.
Leak on a quiet plastic main?
Start with SoµndSens or DXmic Pro — both tuned for low plastic-pipe noise.
Need 1 metre accuracy fast?
Correlate with Touch Pro and its automated AFIS filtering.
Surveying on foot?
Use Lmic or the TMic listening stick for ground-microphone soundings.
Want leaks flagged automatically?
Deploy Permalog+ or PermaNET loggers for permanent monitoring.
Choose A Tool Family, Then Open The Product Page.
Cards are intentionally brief. Click through when you need accuracy figures, pipe-material notes, app details and comparisons.
Pinpoint the leak position to ~1 metre
For fixing the exact leak location between two sensors — the fastest route from "there is a leak" to "dig here".
Listen on the surface and confirm the loudest point
For pinpointing and confirming leaks by ear — over pavement, soil and fittings — before committing to a dig.
DXmic Pro
Smart ground microphone with frequency shifting and auto-filtering to confirm leaks, even on plastic pipe.

Lmic
Compact dual-mode kit — tripod ground microphone plus probe rods for soundings across any surface.

TMic
Digital listening stick for quick contact soundings on fittings, hydrants and valves.

For permanent and patrol monitoring that listens overnight and tells the team where to investigate.
Tell Us The Pipe, The Surface And The Noise.
RD-Palmer can narrow the HWM choice by pipe material, leak type, surface condition, survey method and urgency.
