摘要： An automatic fluid shut-off device for interrupting fluid flow through a fluid supply path in a fluid delivery system. The automatic fluid shut-off device includes: a fluid flow sensor structured and disposed for monitoring fluid flow in a fluid supply path; a control panel housing, a central processing unit, and including a visual display panel, programming buttons, and indicator lights; and either a solenoid actuated fluid shut-off valve or relay that interrupts power to a fluid pump. The fluid flow sensor monitors fluid flow in the fluid supply path and outputs the fluid flow data to the central processing unit. The central processing unit compares the measured fluid flow value with the value preprogrammed for the particular operating conditions or for the particular active zone in a multi-zone fluid delivery system. The central processing unit actuates the solenoid to close the shut-off valve and/or trigger the relay to an open position to thereby stop fluid flow through the system when the measured fluid flow value exceeds the applicable preprogrammed maximum value. An audible alarm tone and flashing light are also triggered when the measured fluid flow value exceeds the maximum value. User inputs are provided for inputting maximum fluid flow values and for selecting particular operating modes for the system.

摘要： A water distribution system protects against water leaks by shutting off the water if a pre-determined flow is detected for more than a set period of time. The time may be changed to any value between one minute and four or more hours. When the pre-determined flow continues past the set time, the main shut off will activate for two seconds, closing the system.

摘要： A water safety valve, system and method for detecting and shutting off water flow due to leaks or breaks in a water line in which the water flow is at a very low rate on the order of three to five fluid ounces per minute but having the capability of passing large flows of three hundred to five hundred times this amount. The system provides an automatic fluid shut off with an over-ride timer with an automatic return to normal operation when a predetermined period has expired. It further allows simple shut off and activation of the system with a single conveniently located control.

摘要： A method is provided to detect leakage from a conduit through which a stream of fluid flows and to indicate when there is a leakage condition or a no leakage condition. The method includes measuring at least one variable of a group consisting of fluid pressure and fluid flow rate over a period of time and at least one location of the stream to provide a data set representing the variable at the location and over the period of time. A statistical probability of obtaining the data set from the measurement under a first hypothesis that no leakage occurs is determined and a statistical probability of obtaining the data set from the measurement under a second hypothesis that leakage occurs is determined. One of the hypotheses is selected as being true if the probability of obtaining the data set from the measurement under the selected hypothesis is larger than the probability of obtaining the data set from the measurement under the other hypothesis. Should the second hypothesis be selected, a signal is initiated which provides an alarm to indicate that a leakage condition exists. Should the first hypothesis be selected a signal is initiated which indicates that a no leakage condition exists. In some embodiments of the invention, sequential probability ratio tests are used to determine the selected hypothesis.

摘要： A water flow monitoring system for determining the presence of leaks in plumbing pipes having water flowing through the pipes under high pressure includes a flow monitor which is mounted to the pipe for sensing the flow of water through the pipe. A timer and/or accumulated volume meter is associated with the flow monitor to determine when the flow has continued for a preselected period of time, and/or when the amount of water has exceeded a preselected accumulated volume threshold. Upon detection of flow for the preselected period of time, and/or preselected accumulated volume threshold, a valve is actuated to stop flow through the pipe.

摘要： The fluid control device of the present invention combines a flow sensing unit in series with a control valve. The flow sensing unit is of the displacement piston type and the flow rate is electronically sensed. A single action poppet valve assembly facilitates the use of a self contained power supply for use in remote locations. A microprocessor monitors parameters including pressure, flow rate, temperature and flow volume, and is enabled to activate the control valve to the open or shut positions based upon any combination of the monitored parameters.
