In-pipe leak detection robot for fluid distribution system

Abstract

An autonomous and low-cost system for leak detection in fluid distribution system is proposed in this paper. The proposed robotic system is capable of detecting small leaks. This in-line pipe leak detection robot uses the presence of a radial pressure gradient near the leak site. The pressure gradient creates suction force, which in turn tilts the disc from neutral position. This rotation is detected using gyro-accelerometer sensor. This method does not require skilled operators. Leak signals are sent wirelessly using Bluetooth to computer for inspection.
