Best Ground Microphone for Leak Detection

Ground microphone leak detection

The ground microphone is a high sensitivity sensor which is equipped with the characteristic ball to eliminate wind noise transmitting through the sensor cable to help find water leak detection

Advantages of Acoustic Ground Microphone Technology

  • Confirms whether or not a leak is present.
  • Quickest and easiest way to search for, detect, and pinpoint a leak.
  • Water service is not interrupted.
  • Works best on small diameter metallic pipes.

Limitations of Acoustic Ground Microphone Technology

  • Background noise can interfere with leak sounds.
  • Pressure must be high enough for the leak to produce a sound.
  • Maximum depth for pinpointing is 5-8 feet for 1-3 gallon per minute (GPM) leak.
  • Pinpointing over soft soil or grass cover is more difficult.
  • Pinpointing is sometimes only possible at night.
  • Difficult to find leaks in non-metallic piping.
  • Takes years of experience to develop an ear for hearing and pinpointing leaks.

Leak detection and acoustic pipe location

Whether you need it for laying out pipes or to narrow down the search or pinpoint a leak – the highly-sophisticat­ed LD6000 and the high-quality microphone, which both carry the hallmarks of a product made in Germany, allow you to determine even the tiniest of leaks and display the signal before it is processed.

  • Benefits in practice:
  • Acoustic and trace gas leak detection in only one device
  • High-resolution colour graphic display with touchscreen functions
  • The only one of its kind in its class. State-of-the-art smart function for even faster pinpoint leak detection (patent filed)
  • Numerous preprogrammed common applications for quick access
  • All filters and parameters can be configured individually
  • Pipe detection mode
  • Complies with all guidelines govern­ing according to VBG 121 (when used with original headphones) (VBG – trade association safety regulations)
  • Highly-sensitive, high-quality, robust precision microphone made in Germany

PQWT-L400 outdoor water leak detector

PQWT-L series is the newly updated and multi-functional water leak detector, it is applied to different detecting leakage of outdoor water pipe, fire pipe,heating system, indoor water pipe, and underground heating floor pipe. By collecting and analyzing leakage signal, it solves the problem of pressure pipe water leak.
The major components of the instrument include: Host Machine, Noise Reduction headphone, Medium Sensor(for outdoor normal environment), Large Sensor(for outdoor noisy environment), Triangular Sensor (for indoor ground), Square Sensor (for narrow spaces such as walls and cabinets.etc),Telescopic Pole (for connecting sensors), Sound pole (for inserting soft soil,lawn)

Gutermann AQUASCOPE 550

The AquaScope 550 is the world’s first and only acoustic leak detector to have “frequency shifting” to assist in the pinpointing of low frequency leaks found in PVC and large diameter pipes. Furthermore, the AquaScope 550 possesses impressive amplification capabilities. The professional leak hunter will therefore find even difficult leaks that are undetectable with other equipment. With a host of other advanced features, this must be the acoustic microphone of choice for the demanding leak operator.

Sewerin AQUAPHON A100

The Aquaphon A100 incorporates a novel technology to makes this danger a thing of the past. When a very loud noise is picked up the sound to the headphones is immediately muffled. If the sound increases further, the headphones are switched off to protect your hearing.

We do not all hear best at the same frequencies; some people can hear higher frequencies better than lower ones and vice versa. Water leaks do not all produce sounds at the same frequency. Interfering noises (trains, cars, dogs barking) can all make listening for water leaks at certain frequencies very difficult.
The Aquaphon A100 has a number of ways to change the frequencies that you hear to render the leak noise loudest for you.

  • Suit yourself – select your own band of frequency filters:
    By applying your own choice of frequency filters you can listen to any frequency grouping that best suits your hearing and  the water leak noise being listened to. 
  • Let the Aquaphon do it for you – Automatic frequency analysis:
    The Aquaphon takes a sample of the noise which is analysed  and  the optimum frequency range filter is set automatically. This can greatly assist those with less experience making the sound of the water leak particularly clear.
