Listening Electronic Water Leak Detector Kit For Plumbing PQWT L50

PQWT-L50 pipepine water leak detector collects leaking sound signal through its sensor, After the collected signal is processed by the host, it is displayed on the host screen in the form of visible spectrum and signal bar. At the same time, the sound will also be output to its headphones through the host. Through the combination of "listening to abnormal noise" and "observing abnormal signal bar", it is easy to find the leak point

Operate process

1: First, use the "General" mode in the leak detector to detect the entire pipeline, through the sound of the headset, and the cursor signal display on the instrument screen, to find the suspected leak in the pipeline. Under the same conditions (the position of the leak-proof tube), the sound of the earphone and the cursor signal of the instrument are relatively consistent. However, at the location where the pipeline leaks, the sound of the earphone and the cursor signal of the instrument will be abnormal (the sound of the earphone will become louder, and the cursor signal of the instrument will continue to increase). Comparing the abnormal sound of the earphone and the cursor signal to determine the suspected water leakage point

2. In order to verify the accuracy of the "suspected leak point", the "Locating" mode in the leak detector can be used for detection. The positioning mode has 24 fixed frequencies. Taking the pipeline pressure of 8 kg as an example, generally, a frequency of about 800HZ can be selected as the center frequency. Taking the suspected leak point as the center, extend the inspection and comparison to both ends, and determine that the strongest signal point is the "suspected leak point" (that is, the excavation point). ).
