PQWT-L7000 pipe leak detector for professional pipeline detection underground floor 5m

The major components of the instrument include:

Host Machine (touch screen)

Noise Reduction headphone

Middle Sensor(for outdoor normal environment),

Telescopic Pole (for connecting the sensors),

Sound pole (for inserting soft soil, lawn)

Large Sensor(for outdoor noisy environment)

Functions:

Pinpointing of leaks

The L7000 receiver is also available to buy with an optional integrated module for positioning. The GNSS (Global Navigation Satellite System) module stores the current user position when a leak noise is identified. This means the exact geographic position of the leak can be associated with the noise, making it available for documentation at a later date. Noises stored temporarily in the audio player can also be subsequently associated with the appropriate location data once the measurement has been stored.

Suppression of interfering peaks

The feature of peak suppression helps with optimisation in situations where one area of the correlation function is selected and then suppressed. The graph is then normalised in accordance with the next smallest peak, making it much easier to identify. If more than one leak is detected within the correlation line, peak suppression can be used to separate the visible peaks from each other.

Measuring sound velocity

When measuring sound velocity, a second source of noise at a known location is created in addition to the real leak. Two measurements are then taken (one with the second source of noise and one without), and they are used to calculate the sound velocity on the measuring section. The measurements displayed on the receiver focus clearly on the second measurement, paying special attention to the position of the additional sound source. The result is rapid measurement of the sound velocity in just a few steps.

Documentation with WaterCom software

Measurements saved in L7000 receiver can be transferred quickly and easily to a computer via USB. Just connect the receiver to the computer via cable and the measuring data will be transferred automatically.
It is possible to set up different user and customer data sets in the software. The position of the location for each measurement is shown on an online map (e.g. Google Maps). The locations on the map can be edited, meaning the exact position of the radio transmitter or damage detected by the ground microphone can be pinpointed exactly. It is also possible to add notes to any measurement or point of damage. The software can generate PDFs to produce paper documentation of any measurements.
Noises which have been recorded can be played back using the player integrated into WaterCom. If the software is used regularly to save measurements, it will start to build up a useful noise database. This can then be used, for example, to train new starters in leak detection in what to listen out for.
