摘要： A method and apparatus are disclosed for calibrating a sensor for flowing fluid in a system including a dialysis monitor, a fluid inlet and a fluid outlet, the method including applying a first pressure to the flowing fluid and detecting a first flow of the flowing fluid at the fluid input and the fluid output, applying a second pressure to the flowing fluid and detecting a second flow of the flowing fluid at the fluid input and the fluid output, and determining whether any detected differences between the first and second flows are the result of leakage in the system or are caused by the sensor.

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.

摘要： A multipurpose residential plumbing and fire sprinkler system or, more simply, a multipurpose piping system ("MPS") is a system for providing water to both domestic uses (e.g., showers, sinks, toilets) and to sprinklers for fire protection. The invention provides an apparatus and method for alarming when one or more sprinklers connected to the MPS are activated by a fire. The invention uses a water flow detector. In particular, the invention provides an apparatus and method for distinguishing typical domestic water flow from the flow caused by one or more sprinkler heads.
