LEAK DETECTOR
First Claim
1. A leak detector for detecting and locating leaks in a water supply pipe of plastics, the leak detector comprising a first sensor at a first position arranged to detect a leak signal travelling along a pipe, a second sensor arranged to detect a leak signal travelling along the pipe at a second position spaced from the first position, and a processing device adapted to receive the signals from the first sensor and the second sensor, the processing device adapted to determine the velocity of the signals from measurement of characteristics of the leak signals and, using the velocity and distance between the first sensor and the second sensor, determine the location of a leak.

Abstract
A leak detector for detecting and locating leaks in a water supply pipe of plastics, the leak detector comprising a first sensor at a first position arranged to detect a leak signal travelling along a pipe, a second sensor arranged to detect a leak signal travelling along the pipe at a second position spaced from the first position, and a processing device adapted to receive the signals from the first sensor and the second sensor. The processing device may be adapted to determine the velocity of the signals from characteristics of the leak signals. The processing device is adapted to use the velocity and distance between the first sensor and the second sensor to determine the location of a leak. The characteristics may be the relationship between the phase and frequency of the leak signals.
