Abstract: Systems and methods for operating a fluid supply system. The methods comprise: using a micro-turbine and an Energy Harvesting Circuit (“EHC”) to harvest energy from a fluid flowing through a pipeline; operating a switch to disconnect the EHC from the micro-turbine when an amount of energy harvested reaches a threshold value; detecting by a sensor device an amount of natural fluid flow through the pipeline while the EHC is disconnected from the micro-turbine; and operating the switch to reconnect the EHC to the micro-turbine after the amount of natural fluid flow has been detected.

Abstract: 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. The fluid flow sensor is incorporated into a Wheatstone bridge circuit, which is used to provide increased sensitivity to the outputs of the sensors, 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. An alternative embodiment utilizes a single sensor and separate heater which work together to determine heat propagation times which in turn is used to calculate flow rate. Based on the sensor readings, the flow may be adjusted to prevent damage and leaks by relieving the system of excess pressure.

Abstract: A system used in monitoring one or more operating parameters of a coolant-fluid cooled industrial installation includes one or more an acoustic sensors positioned to receive and sense one or more acoustic signals in an installation coolant-fluid flow. The acoustic sensor assembly operates to emit and sense acoustic signals at frequency ranges above and/or below the background noise frequency ranges which are associated with the normal industrial installation operation. Output data signals representative of sensed acoustic signals are compared to target frequency profiles predetermined as representing an acoustic frequency associated with a predetermined installation operating parameter or event.

Abstract: The system and method for wireless water leak detection provides for manual prevention of external action, such as an external alarm and/or valve shut-off, if a leak sensor can be reached by a respondent within a pre-set time threshold. Upon detection of a leak by a leak sensor, a local alarm, such as an audible alarm or the like, is initiated. Additionally, at the time of detection, a first time is recorded. A first alarm signal is transmitted from the leak sensor to a base station. The first alarm signal includes data representative of the recorded first time. If manual input is not received by the leak sensor within a pre-set time threshold measured from the first time, then the base station transmits a second alarm signal to at least one external device, and may further wirelessly transmit a shut-off signal to a valve controller for closing an associated valve.

Abstract: Water leaks and other anomalies in irrigation systems may be detected by analysis of energy consumption data captured from a utility power meter, and particularly energy data from smart meters that service water pumps. Furthermore, water usage can be measured indirectly from the energy required to move it given an understanding of its operating condition that ties water flow and electrical power. Unlike existing solutions that use water meters or other sensors, embodiments of the present method described herein detect water leaks and other anomalies from the electrical load for the water pump(s) and track the operating condition of the pump.

Abstract: A sprinkling or irrigation system includes a sprinkler controller that is capable of detecting a leak in one or more zones of the system. The system include a main valve and an adjustable valve in a bypass line around the main valve. The adjustable valve is set to a partially closed state such that a selected on of the zones produces a pressure at a selected proportion of the static pressure provided by the water source such as half the static pressure. A leak is detected when a zone, with the main valve closed and the adjustable valve in the partially closed state, produced a test pressure that is substantially lower than the selected proportion of the static pressure, as modified by a test factor.
