摘要： A flow sensor having an inlet and an outlet comprising: a plate moving in response to fluid flow therethrough, being displaced further as flow increases; a sensor for determining moving plate's position and creating an electronic signal related thereto; a biasing means for biasing the plate towards the sensor's inlet end. The sensor may include a sealing means for preventing flow therethrough until a specified differential pressure is reached allowing the device to be used as a bypass mechanism. The sealing means may also constitute a check valve means to prevent flow in an undesired direction. The check means comprises: a bullet rod adapted to be received within an orifice defined in a moving plate, such that the bullet rod prevents flow through the orifice until the moving plate is displaced past a terminal end of the bullet rod; and a plate means sealingly and slidingly received within a cylinder, which is closed for a portion of its length and open for another portion of its length, such that flow is prevented until the plate is displaced past the closed portion of the cylinder. The method using the sensor in multipurpose piping systems includes use of the apparatus in a system incorporating at least one fire sprinkler, the piping system also preferably providing at least one other use in the structure. The other use in the structure may be supplying domestic needs, or supplying heating/cooling water for a heating/air conditioning system.

摘要： A hot water tank monitoring system is designed to shut off the water supply to the hot water tank and to shut off either the electrical supply or the gas supply to the heating unit of the hot water tank in response to sensing of malfunction of one or more of a number of different sensed parameters. These parameters include a water leak detector located beneath the water tank, a water level float sensor, a temperature sensor to sense excess temperature, and a pressure sensor located in the line between the pressure relief valve and the blow-out outlet of the water tank. Signals from the various sensors are supplied to a controller, which provides signals to a LED status indicator, and also operates to provide alarm signals through a modem over telephone lines to remote locations and to operate an alarm.

摘要： Disclosed are a method for assembling a polishing while inspecting for air leakage in the polishing head and an apparatus for performing the same. By the present invention, a polishing head may be tested for air leakage at each assembly step thereof, so that the polishing head may be assembled free of air leakage, thereby reducing testing time of the polishing head, and failure of the polishing head due to air leakage may be prevented. The apparatus includes a housing supporting the polishing head and having coupling lines coupled with ends of tubes provided in the assembled polishing head, or the polishing head being assembled. A pneumatic pressure regulating section selectively supplies positive pressure or vacuum to the tubes through the coupling lines. A sensor section detects the pressure and level of vacuum in the tubes. A determining section determines if there is air leakage in the polishing head.

摘要： A multi-tube differential pressure testing system for testing catalyst filled tubes of tube and shell type catalytic reactors having an upper tube sheet and multiple catalyst tubes having upper ends thereof fixed to the upper tube sheet. The system has at least one mobile support device for selective positioning on the upper tube sheet of a catalytic reactor. A plurality of testing tubes are mounted to the mobile support device and are selectively positionable in sealed gas pressure communicating engagement with the upper ends of a plurality of reactor tubes. A pressure testing gas delivery system is interconnected with the testing tubes and is adapted for communicating pressurized gas at a selected test pressure to the testing tubes and into the reactor tubes being engaged thereby. A differential pressure measurement system is provided in the testing system for measuring the back pressure resulting from application of gas pressure at the selected test pressure to the reactor tubes being tested and having a differential pressure indicator system providing a visual indication of the resulting back pressure of each reactor tube being tested.

摘要： A water monitoring and control system adapted for residential and commercial use automatically shuts off the water supply after a predetermined period of time, whether the flow is intentional or unintentional, thereby preventing damage from leaks and other malfunctions. The system also gives an indication of all water flow ranging from normal usage to leakage of a few drops and large flow, as would typically occur due to a break in the plumbing system. The system is easily bypassed in the event of power outages. In terms of hardware, the main components of the system include a normally closed water shut-off valve, preferably solenoid-operated. A pressure-responsive switch senses changes in water pressure and sends a signal in the event of a pressure drop, and a timer is provided to start a timing cycle when there is a demand for water, either intentional or unintentional, and shut-off the flow after a predetermined period of time selected by the user. The system also preferably incorporates a water demand indicator used to visually indicate water usage in the system, again, whether it is intentional or unintentional.

摘要： An improved flow sensor of the type having inlet and outlet ports, a moving plate means for moving in response to fluid flow through the sensor, a sensor means for sensing the movement of the moving plate and creating a signal related to its location, and a biasing means for biasing the plate towards the inlet (nullbase elementsnull). One improvement comprises the moving plate composed of a magnetizable material and the sensor means comprised of a steel sensor disposed adjacent to a path traveled by the moving plate for sensing the location of the moving plate. Another improvement is to a sensor having, in addition to the base elements, a sealing means, the improved sealing means comprising: a bullet rod slidingly received in a bullet port mounted within the sensor and including at a terminal end of the bullet rod a sealing plate adapted to sealingly engage the moving orifice plate, the bullet rod moving in relation to the moving plate until a flared end of the bullet rod engages a bullet port, causing the sealing plate to disengage from the moving plate allowing fluid to pass through the orifice plate. Still another improvement to a sensor having the base elements plus a sealing means comprises a second sealing means for preventing flow between an outer periphery of the moving plate and an inner surface of the sensor. A system for using these improved sensors in a plumbing system for flow detection and leak prevention.
