A non-invasive thermal dispersion flow meter with chronometric monitor for fluid leak detection includes a heater, an ambient temperature sensor and a flow rate sensor which are configured to sense the temperature of a fluid in a conduit, and then monitor the flow of that fluid through the conduit. Based upon the ambient temperature sensor readings, the flow rate sensor and heater may be adjusted to optimize the operation of the system to detect leaks. Based on the sensor readings, the flow may be adjusted to prevent damage and leaks by relieving the system of excess pressure. Geographic location, occupancy sensors and occupant identifiers are used to control the system to facilitate operation and minimize leak damage when occupants are away.

The user is guided through environmental and/or location considerations associated with the condition, instructed to prepare the location for infrared image acquisition, and guided through a process for analyzing captured images.

The disclosure relates to a mechanical seal for sealing a fluid-conducting channel and/or space extending in a stationary component and/or a rotating component from the environment, having a slide ring which is supported in the axial direction against a counter ring in a sealing manner and, to compensate for wear on its front-end seal face or on a counter face, is supported against the counter ring elastically and movably in the axial direction with this seal face; having a position sensor to detect the position of the slide ring in the axial direction. The disclosure is characterized in that a temperature sensor is provided on a leakage side of the seal face facing away from the channel and/or space, which sensor at least indirectly detects a temperature which is dependent on the magnitude of a leakage flow passing from the channel and/or space via the seal face.

A method of detecting and identifying leaking underground pipes for properties having a slab or other type of foundation with a plurality of manifolds utilized to distribute water in the plumbing system of the property. The method includes identifying and detecting a starting fixture to start testing to determine a possible location of an underground leak and performing a series of temperature test checks to determine a number of relevant factors, including, whether an underground leak is before or after a manifold, the feed lines and/or distribution lines of a manifold, and a destination of the distribution lines of the manifold. The series of temperature tests using heating and cooling elements identifies which pipeline contains the underground leak and identifies the point where the pipeline enters a ground (Point A) and the exit point where the pipe exits a ground (Point B) in order to mark these specific pipelines.

A method for locating a leak (19) in a water supply network with a water source (11) and one or more water consumption meters (21, 22) on the consumer side. The method includes calculating a length of the pipe (17) between the consumption meter (21) and the leak (19) location based on a temporal temperature curve and a quantity of water flowing through the at least one consumption meter (21).

Various techniques are disclosed to provide a quantification of a gas leak based on an image of a gas plume generated by the leak. An image location that corresponds to the origin of the gas leak is determined. An exit border is disposed on the image based on the image location that corresponds to the origin of the gas leak. A gas leak rate is computed based at least on gas concentration values of the pixels that overlap the exit border.

An apparatus for automatic leak detection, including a chamber to enclose a test specimen. A vacuum pump is in selectable fluid communication via an adiabatic noise cancellation valve with the chamber. A pressure transducer determines a pressure in the test specimen and transmits a pressure signal to a controller. The controller is to control the adiabatic noise cancellation valve to cause the vacuum pump to draw a vacuum from a space between the test specimen and the chamber thereby creating an adiabatic noise cancelling condition in which a temperature of the test specimen is stabilized. The controller is to control a flow of a test gas into the test specimen, and to determine a pressure decay rate from the pressure signal. The controller is to determine if the test specimen meets a leak test specification based on the pressure decay rate under the adiabatic noise cancelling condition.
