摘要： A method and an apparatus for finding the location of one or more holes in a fluid flow system such as pipe, duct, or conduit using one or more tracers that interact with or can be chemically or physically differentiated from those of the liquid or gas contents located outside the system and pulled back into the system when the system is placed under a vacuum. The preferred embodiment of this detection and location method uses one or more interactive tracers that are injected into a pipe or duct that may be leaking at one location and then monitor the concentration of these tracers at the same or another location in the pipe or duct. Detection and location are accomplished by analysis of the characteristic features of measured curves of tracer concentration. Various types of interactive tracers may be used, including partitioning and reactive tracer gaseous tracers.

摘要： A method and an apparatus for detecting, locating, and quantifying explosive materials and devices, and naturally occurring and man-made dangerous or hazardous biological and chemical materials and devices in ducts or piping systems, or other fluid flow systems in buildings such as residential, office, industrial, and power plants, transportation systems such as ships, airplanes, subways, and trains, and various types of infrastructure such as dams, tunnels, or bridges, and in the rooms, compartments, enclosures, containers, or difficult to access areas in these buildings, transportation systems, and structures. The preferred embodiment of this detection and location method uses a conservative tracer and one or more interactive tracers that are injected into the duct or area to be searched at one location and then monitored at the same or another location in the duct or area. Alternative embodiments, which are quicker and just as accurate for detection and location, require only the use of interactive tracers. Detection, location, and quantification are accomplished by analysis of the characteristic features of measured curves of tracer concentration. Various types of interactive tracers may be used, including partitioning and reactive tracer gaseous tracers.

摘要： A Positive Displacement Metering Systems (PDMS) using a Water Fill Cylinder (WFC) is provided. It will replace or be paired with an existing conventional water meter. The primary advantage of the PDMS is its ability to detect and measure “micro” flow rates. The PDMS allows the water utility to bill for all water consumed by the customer. The PDMS will only allow 100% detectable flow rates to pass through the water meter attached. Flow rates which are undetectable, or only partially detectable will be accounted for. The PDMS will report the sum of the two meters to the utility. The PDMS will also function as a leak detection device and water conservation tool, will perform automatic or remotely controlled functions like turning off water, when a high flow leak is detected, and report directly to the water utility or tenant of the property being monitored.
