Measurement Working principle: Indoor Pipeline Water Leak Detector collects leaking sound signal through its sensor, collected signal will be processed by host machine and displayed on the host machine screen in the form of visual spectrum and signal bars. At the same time, the sound will also be output to its earphone through the host machine. Water leakage point can be found out easily through the combination of "listening to the abnormal sound" and "observing the abnormal signal bars”. High Precision Detector，effectively solving the problem of water leakage in the household pipeline Electronic Earphone Leak Detector Water Pipe Detection Equipment Kit- Host machine, 1 x Earphone, 1XSquare sensor ，1xTriangle sensor. The closer the detector is to the leak, the greater the jerk will sound, indicating that the Columnar will be higher and the user will be able to operate to detect the leak. PQWT-L50 Indoor Pipeline Water Leak Detector is the latest generation of intelligent water leak detector independently developed by Hunan Puqi Geologic Exploration Equipment Institute, it is designed for household pipe water leakage. This device is equipped with a triangular sensor and a square sensor. It is applied to different detecting environment like indoor floors, walls, cabinets, etc. This device achieves high accuracy by collection and analysis of leaking sound signal, effectively solving the problem of water leakage in the household pipeline.
