摘要： Discloses a check valve and a leak indicator for indicating the position of a valve closure means relative to spaced apart inlet and outlet ports. The invention involves the use of an elongated cylindrical valve chamber and a spring loaded valve closure mounted therein for reciprocating movement between the inlet and outlet ports, so as to require maximum axial movement to open the outlet port. Magnetic indicating means situated outside the valve housing and outside the valve chamber are completely isolated and separated from the fluids in the valve chamber, and move responsive to the axial movement of the reciprocating valve closure to indicate the smallest leak.

摘要： There is disclosed herein an electronic monitoring system for pipelines and the like utilizing counting techniques for determining the difference between fluid volume supplied into a pipeline and the fluid volume removed from the pipeline. An error factor is employed and, based upon the volume difference, provides compensation for normal difference between the input and output volume measuring devices. This error factor then compensates for the normal difference between input and output volume. Abnormal deviations can then be detected to determine fluid leaks and the like for actuating alarm and control circuits for providing an alarm and/or terminating fluid flow in the pipeline system. There is also disclosed herein the manner in which the present electronic system can be utilized for monitoring a pipeline system with multiple input meters or outputs meters. There is also disclosed herein methods for precisely determining the normal difference between input and output meters.

摘要： In a method of estimating water consumption of a fixture which uses water, measurements of at least two of ambient sound, contact sound, and temperature are captured via a sensor assembly disposed proximate the fixture. From the captured measurements both a number of uses of the fixture and a duration of use each of the uses of the fixture are determined. Based on the number of uses and duration of the uses, water consumed by the fixture and consumables used in conjunction with the fixture are estimated.

摘要： Devices, systems and methods for leak detection/identification are provided herein. Also provided are devices, systems and methods for monitoring and/or measuring fluid usage. In some aspects, a system comprising a sensor, a processing system, and a platform are provided. In some aspects, the sensor may be coupled to a spinning device. The sensor can be configured to detect fluid data, which can comprise, for example, displacement data of liquid and/or movement data associated with the liquid in a container and/or flow data associated with a flow of fluid in a conduit. The processing system can be coupled with the sensor and configured to communicate the fluid data. The platform can comprise an application communicatively coupled to one or more databases storing evaluation data (e.g., known pattern data) and configured to receive the fluid data and determine if there is a leak.

摘要： 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.

摘要： An observed operational state can include an operational state of one or more system devices. A sensor can emit, in response to a detected observable condition reflective of a given operational state, a simulated signal reflective of a different operational state as a proxy for the detected condition. A controller receiving such a proxy signal can, at least partially responsively to the proxy signal, issue a command corresponding to the given operational state. For example, a leak detector can emit in response to a detected leak, or a flow-rate sensor can emit in response to a detected flow-rate of a liquid, a simulated fan-speed tachometer signal representative of a selected fan speed. At least partially in response to observing a simulated tachometer signal, a controller can issue a system command corresponding to an underlying system condition for which the simulated tachometer signal is a proxy.
