PQWT-L40 geofono detector leak water is our institute newly design and developed by Hunan Puqi water environment institute , it is mainly use to home water leakage detector, it detector depth 0-50 cm

the device equip the traingle sensor,it mainly to use detector the indoor floor ground.This device achieves high accuracy by collection and analysis of leaking sound signal, effectively solving the problem of water leakage in the household pipeline

Operate process

1:First, use the "general" mode in the leak detector to detect the entire pipeline, and look for suspected leaks in the pipeline through the sound of the headset, and the cursor signal display on the instrument screen. Under the same circumstances (the position of the leak-proof pipe), the sound of the earphone and the cursor signal of the instrument are relatively consistent. However, at the position where the pipe leaks, the sound of the earphone and the cursor signal of the instrument will be abnormal (the sound of the earphone will increase in volume, and the cursor signal of the instrument will also increase continuously). Compare the abnormality in the earphone sound and the cursor signal to determine the suspected water leakage point

2. In order to verify the accuracy of the "suspected leaking point", the "locating" mode in the leak detector can be used for detection. The locating mode has 24 fixed frequencies. Taking the pipeline pressure guaranteed at 8 kg as an example, you can generally choose a frequency of about 800HZ as the center frequency, with the suspected leakage point as the center, extend to both ends to check and compare to determine the signal The strongest point is the "suspected leaking point" (that is, the excavation point).
