Dayu Electronics M45 Leak Detection Listening Device Applied to Municipal Water Supply Pipeline Leak Monitoring

Engineers working on pipeline monitoring and underwater noise detection all know that some working conditions sound simple, but once you actually get started, they're full of pitfalls:

Municipal water supply pipelines are buried deep underground. To install a leak monitoring sensor, you have to shut off water, cut openings, and weld — not only are construction costs high, but resident complaint calls come one after another;

Chemical plant pipeline surfaces are covered in rust. Ordinary sensors can't be strapped on or adhered securely — they fall off after just two days;

For underwater noise source localization, if sensor sensitivity is insufficient, weak signals simply cannot be captured, and localization is pure guesswork;

Ship/underwater equipment housings are sealed metal structures. To monitor equipment operating status, you can't cut openings without compromising housing seal integrity...

Ordinary hydrophones either have complicated installation, insufficient sensitivity, or inadequate protection ratings for humid environments. Searching the market, there aren't many options that can simultaneously deliver "rapid deployment" and "high-sensitivity listening."

Dayu Electronics M45 Leak Detection Hydrophone — dual-mode magnetic/collar mounting. Stick it on or strap it on and it's ready to "listen." IP68 fully waterproof, stainless steel housing. It gets the job done.

I. An "Underwater Long-Range Ear" Built for Rapid Deployment

The Dayu Electronics M45 Leak Detection Hydrophone is essentially a non-contact underwater acoustic sensor designed specifically for rapid deployment. It uses powerful magnets to directly attach piezoelectric ceramic elements to the metal outer wall of pipelines, tanks, or ship hulls — no cutting, no water shutoff, no complex installation required. It can "hear" internal water acoustic signals right through the metal.

This kind of "no cutting, no water shutoff, no complex installation" product can save you how much time and money.

Just as a doctor uses a stethoscope to listen to a heartbeat — the M45 presses tightly against the outer pipe wall, "listening" to internal water acoustic signals and passing them to the backend system for analysis and identification.

Its core component is a high-sensitivity piezoelectric ceramic transducer responsible for converting water acoustic signals into electrical signals. The acquired signals are processed by a built-in amplifier circuit and output via RS-485 or analog interface for analysis by a host computer or data acquisition system. The entire unit features a 304 stainless steel housing, with the complete cable assembly rated IP68. From sensor to signal output, the entire chain is hermetically sealed and reliable — impervious to humidity, corrosion, and underwater environments.

II. Three Core Advantages, Purpose-Built to Fix Every "Can't Hear It" Problem

Magnetic/Collar Mounting — No Water Shutoff, No Cutting

Traditional leak monitoring requires cutting into the pipeline and welding bases, which means shutting off water and lengthy construction periods at high cost. The M45 offers two mounting options: magnetic and collar clamp. On ferrous pipelines, one click and the magnet holds firmly; for surface-visible non-ferrous pipelines, securing with a collar clamp also requires no cutting or water shutoff — deployment takes just minutes.

One construction worker costs 500 RMB per day. If installation is completed in a manhole in just over ten minutes, that means how much labor cost savings?

High-Sensitivity Listening — Small Leaks Can't Escape

Sensitivity: ≥ -160 dB (Vref: 1V/μPascal), frequency response 20Hz ~ 20kHz.

A leak the size of a pen refill on a water supply pipe — can be captured;

Acoustic characteristics of liquid flow inside a pipe — can be distinguished;

Abnormal vibrations in underwater equipment — can be effectively identified.

Everything that should be heard — not a single one gets missed.

IP68 Waterproof + 304 Stainless Steel — Install It Outside and Forget It

Full-unit IP68 protection, 304 stainless steel housing. Humid municipal water well environments, outdoor rainstorm washing, long-term underwater submersion — no water ingress, no corrosion under normal use.

Power consumption ≤150mW (12VDC power supply) — runs on just a few batteries.
