WLD500 Water Leak Detector
User Manual
Read this manual carefully before using this Device
TEKWLD500_V0.1 2
Tekneka WLD500 is an advanced water leak detector, Facilitates users to detect
pipe water leaks up to 5 meters in depth. 7” Digital touch LCD display performs very
well in the outdoor light condition and helps to analyze detected noise frequencies
(1 ~ 10,000 Hz).
This device shows spectrum signals with digital ltering technology & facilitates
users to identify exact leakages in underground metal & plastic pressure pipes.
WLD500 has a multifunction outdoor leakage setting and records both voice &
underground acoustic noise at the same time. It is a lightweight device to carry
anywhere, comes with multi-language support & better long-lasting battery life of 7
hours while operating with the sensor

Working Principle
WLD500 Outdoor Water Pipeline Leak detector collects leaking sound signals
through its high frequency sensor. Received frequency signals were processed & dis-
played on the screen in the form of the visual spectrum (signal bar). At the same
time, it can produce sound signals which will also be heard & record acoustic sounds.
This WLD500 has a unique feature to distinguish between environmental noise and
underground water leak sound. This dierence shall be identied through spectrum signals on
the screen (thick & thin bar in locating mode)
Operating Instructions
1. Fix the carrying strap backside of the monitor to avoid accidental drops. g.1
2. Switch ON the monitor by Press and holding the power button “ ”
until it shows an LED light indication
5. Aer initial boot up, you can see the home
screen options Outdoor/About/Settings.
4. Connect 3.5 jack earphones to the monitor
to hear sound signals.
3. Connect the in-line acoustic sensor cable by matching male & female pins with white dots
marked on the monitor. g. 1.1
6. Select “ Outdoor” mode to access the initial
setup of sensor, detection method & record the
water leak sounds.

Operating Instructions
General Detection mode
7. Default soil texture & pipe material will be
so & plastic. Based on the outdoor environ-
ment you shall select soil texture: Hard/pipe
pipe Material: Plastic, Metal, Unknown
1. “General Detection” or “Locating” mode helps you to detect the water leakage by observing
acoustic sound through the headphone.
2. Select “General Detection” and press the gain button to receive sound frequency from
the sensor. Then press the volume button to enable acoustic sound. Rotate both nobs to incerease
or decrease it’s ranging.g.3.1

3. This mode will pick up the underground and
environmental noises which are used for the quick
detection of water leaks. Detected water leak
spot will be indicated by the maximum spectrum
bars throughout the screen.g 3.2

Locating mode
1. Select “ Locating Mode” and press the gain button to receive sound frequency from the sensor.
Then press the volume button to enable acoustic sound. Rotate both nobs to increase or
decrease it’s ranging.
2. It has 16 signal points, that can be activated individually by touching on the screen.g.3.3
3. First you need to mark the suspected locations randomly or based on the underground
pipe layout.

5. Wait until the thick bar gets stable and then click again on “01” spectrum bar on the screen
to “LOCK” location points. Follow the same procedure to identify multiple signals from dierent
locations.
6. The highest spectrum bar level with a larger frequency value of ‘999’which indicates a
suspected leaking point.
7. Click “EXPORT” to save the generated spectrum graph to SD card in “PicSave” folder as (.bmp)
le format.
4. Now select “01” spectrum bar to start receiving signal from the sample location 01. The Blue
colour thick bar (Underground noise) with “RED colour” highlighted frequency values will appear
on the screen and as you can observe there will be a thin bar which represents
“Instantaneous noise”. Fig 3.4

Recording Settings
1. Select “Settings” to change the date, time, Language and decrease the brightness of
the monitor
2. Wireless transmission: Detected noise can be transmitted to the smartphone which can
be heared by using FM radio app. It is convenient for multiple people to listen at same time,
and it needs to be adjusted to the same frequency in your application.
MIC ON/OFF: Click “MIC O” to record
operator‘s voice which helps to listen
leakage noise along with location voice
notes.
Connect PC: First, connect the USB to PC
and click “Connect PC” to access stored
data.
Refresh: Press stop recording, and click refresh to update recent records in the le browser list.
Delete: Select a le from the le browser and click delete to remove it from the storage.
Note: Saved spectrum data will appear only the device connected to the PC
