Correlation type water leakage detector machine
A correlation type water leakage detector machine is equipped with high sensitive acceleration sensors in two points where the water leak point is placed, the oscillating sound of the very small level generated at the water leak point is caught by two acceleration sensors, and amplifies it with each amplifier. It is put on the electric wave of UHF belt and sends it to the main body. The arrival time interval is accurately requested with the main body by the correlation operation method 、micro computer calculates the position from the distance between two points of sensor and the sound wave velocity of oscillating sound, and displays it on a personal computer.
