Leak detection method and system
TLDR
In this paper, the volume of fluid leakage in a conduit exceeds a predetermined percentage of the total fluid flow by measuring the leakage volume from the conduit and comparing the volume with a predetermined proportion of the volume in total flow.Abstract:
Method and apparatus for determining when the volume of fluid leakage in a conduit exceeds a predetermined percentage of the volume of total fluid flow by measuring the volume of fluid leakage from the conduit, comparing the volume of fluid leakage with a predetermined percentage of the volume of total fluid flow and generating a distinctive signal based on the comparison.read more

Method and apparatus for detecting leaks in a gas pipe line
TL;DR: In this article, a method and apparatus for measuring a gas pressure gradient in each of the upstream and downstream parts of a gas pipe line and detecting a leak in the gas pipeline line in accordance with the pressure gradients is presented.
Patent
Automatic leakage detection system for pipelines carrying fluids
TL;DR: A plurality of ultrasonic flow meter measurement probes are located at spaced intervals along the length of a pipeline carrying a fluid and each probe measures the rate of flow of the fluid at each location along the line.

Method and measurement probe for the performance of measurements in water supply systems
TL;DR: In this paper, a measurement probe is installed permanently at the key points and at the most varied measurement points following one another as closely as possible in the water supply network and can thus contribute, by delivering all the necessary data, to the rapid tracing of leaks with pinpoint accuracy as well as to constant monitoring.
Patent
System and method for detecting and preventing fluid leaks
TL;DR: In this paper, a rate of flow of a portion of fluid flowing through a fluid distribution network over a period of time is monitored and an indication is provided that a leak has been detected.
Patent
Fluid leakage detection apparatus
TL;DR: In this paper, a leakage position between the upstream and downstream points of a fluid passage is detected by using the time difference Δτ between time τ 1 and time τ 2, which elapses until a flow rate change appears at the upstream or downstream points.

Fluid flow metering method and system
TL;DR: In this paper, a fluid flow metering method and system using digital signals and logic for producing a compensated manifestation of fluid flow by the mathematical multiplication of two or more sensed parameters, one parameter being the fluid flow rate and the other one or more parameters being related to a condition of the fluid such as its constituency, pressure, density, dielectric constant, temperature or the like.
