The Underground Water Leak Detector is mainly used to detect leaks in buried tap water pipelines, and a listener to accurately locate the location of the leak point can also be used to accurately locate the leak points of other liquids and gases. Today we focus on understanding the work flow and method of PQWT-CL500 Underground Water Leak Detector. We chose to bury the fire protection pipeline at a depth of 2.5 meters under a certain industrial park. The pipeline is made of metal and the ground is cement road.

 

First of all, we first understand the overall components of the PQWT-CL500 Underground Water Leak Detector: the host cable, headphones, listening rod, sensor, charger.

 

Next we assemble the PQWT-CL500 Underground Water Leak Detector:

(1) Connect the main interface of the cable to the host

(2) Four-core interface access sensor

(3) Connect the headphone cable

 

Turn on the noise canceling switch

 

Bring headphones

 

Long press the start button to enter the start interface, and the measurement is officially started.

There are two main measurement methods for the PQWT-CL500 Underground Water Leak Detector: rough measurement and precise measurement:

 

Rough measurement of the first measurement method

 

  Double-click to select "Spectrum Analysis"

  Enter spectrum analysis measurement mode

  Long press on the handle switch

  Adjust the volume and gain to the proper position

  It is better to hear the sound clearly

  Place the probe on the pavement above the pipe to be detected

  Long press on the cable handle switch to detect

  After completing a point measurement

  Release the handle switch

  Detect every other meter along the pipeline and press the switch to detect

  The sound heard in the headset changes when a leak is detected

  Increase the volume The overall spectrum on the instrument display will increase

  The reaction is more obvious the closer to the leak

  Suspected to be a leaking point here

 

The second measurement method

  Double-click and select "Filter Analysis" to enter the filter analysis measurement mode

  The interface has eight options

  Each option sets different frequency bands according to different pipes and ground materials

  Select the corresponding frequency band for measurement according to the actual measurement site conditions

  Feel free to choose E option according to the measurement environment

  Metal water pipe-hard soil measurement

  The measurement method is the same as the spectrum analysis measurement

  When the distance is far from the leak, the sound in the headphones is relatively stable

  Low signal strength displayed on the instrument

  When a leak is detected, the sound heard in the headset will increase significantly

  The signal strength displayed on the instrument will be significantly higher than other leak-free measurement points

  At this point we can determine that this is the leak point

 

PQWT-CL500 Underground Water Leak Detector Precautions"

1. Never put the sensor probe into water

2. Handle the sensor probe gently.

3. It is recommended to choose the measurement under the circumstance of small environmental interference, it is best to carry out in the middle of the night.

4. If the instrument is left unused for a long time, it needs to be charged once a month.

5. In soft soil detection, it is better to connect the sensor to the sound bar to insert the soil layer.
