Embodiment Construction

[0049] FIG. 1 shows the basic layout of the system parts. The system 1 includes a plurality of sensing modules 2, which correspond to

[0053] According to the layout scheme, the electrodes 11, 12 of the unit 10 shown in FIG. 3 are arranged adjacently on the same plane, and the layout

[0057] It should be understood, however, that the number of cells 10 that may cooperate with the same sensor circuit 20 may be different from four,

[0061] Between making the system 1 practical and limiting the number of sensor circuits 20 in consideration of the detection and localization of leak points

[0063] The subunits 10a-10d may be sized such that the total area covered by the unit 10 is approximately equal to that shown in FIG. 2

[0064] Referring now to FIG. 7, a sensor for measuring the capacitance between the electrodes 11, 12 of the associated four cells 10 is disclosed

[0065] The circuit 20 includes a signal generator 31 connected to a power supply 30. Signal generator 31 is con...

Abstract

A system (1) for detecting and locating leaks in a building floor (50) comprising a sensing module (2) comprising a first surface (51) with a building floor (50) ) and incorporate at least one pair of mutually spaced apart electrodes (11, 12) defining a sensing path extending parallel to the cell major surface (13). A sensing circuit (20) is capable of cooperating with the cell (10) and is configured to apply a voltage between the cell electrodes (11, 12) to measure an electrical property therebetween. The sensing circuit (20) cooperates with a probe (70) arranged to be applied to a second surface (52) of the building layer (50) opposite to the first surface (51) and is configured to act on the cell electrodes (11, A voltage is applied between at least one of 12) and the probe (70) to measure electrical properties therebetween. The control circuit (150) is operatively associated with the sensing circuit (20) and is configured to: based at least on a first measurement from the sensing circuit (20) of an electrical property between the cell electrodes (11, 12) detecting the presence of a leak within the portion of the first surface (51); and a second based at least on electrical properties between at least one of the pair of cell electrodes (11, 12) from the sensing circuit (20) and the probe (70). Measurements are taken to locate leak points (155) within the portion of the first surface (51).

Description

Leak detection and location system and method technical field [0001] The present invention relates to a system and method for detecting and locating leaks in building floors. Background technique In the construction of buildings, it is challenging to provide a watertight layer, especially a watertight flat roof or basement of. Many businesses only offer leak prevention or leak repair services. [0003] Currently, it is difficult to determine whether a flat roof has been successfully waterproofed before a leak occurs inside, potentially creating a into damage. The same is true for roof degradation, where it is impossible to determine if the roof has degraded significantly until a leak occurs inside. [0004] Detecting and locating leaks within buildings is inherently difficult. The main problem with leaks inside is the source of the leak and the scale is unknown. Identify and locate leaks in a timely manner to prevent any damage to internal structures or personal pr...
