Water Use Monitoring Apparatus

The present invention is a water use and/or a water energy use monitoring apparatus that is affixed to the hot and cold water supply piping for continuously (or on demand) monitoring displaying the water and water energy (hot vs. ambient) use within a residential or commercial building. A first wire or wireless means is incorporated to communicate with a remote display for viewing by the owner of a commercial building or occupier/resident of a home. A second optional wire or wireless means can be incorporated that can be monitored by civil, commercial, governmental or municipal operators or agencies, using a remote display and/or recorder means or by a secure wire or wireless communication network (e.g. cell phone technology communication means). A third wireless means communicates water parameter data utilizing typical cell tower technology and/or mesh network technology. The water use monitor apparatus includes a power generation, a microprocessor, temperature and water flow sensors, optional water quality sensors, timing circuits, wireless circuitry, and a display means. A first wired or wireless means is designed to electronically communicate water use and water energy use information to a remotely located display for convenient observation by a commercial operator or occupier, or resident. An optional second wireless means is designed to electronically communicate water and/or water energy use information to governmental or municipal operators or agencies.

Method for surveying the condition of a control valve, and a valve apparatus

PCT No. PCT/FI97/00359 Sec. 371 Date Dec. 4, 1999 Sec. 102(e) Date Dec. 4, 1999 PCT Filed Jun. 9, 1997 PCT Pub. No. WO97/48026 PCT Pub. Date Dec. 18, 1997A method and a valve apparatus for surveying the condition of a control valve. The position of the valve (101) is adjusted by means of an actuator (103) controlled by an electropneumatic positioner (104) and operated by means of pressure medium. The operation of the valve is monitored by sensors (109, 110, 107) that read the readings from the control signal, the input pressure of the positioner, the difference between the input and output pressure of the actuator, and the position of the valve. A fault causing a deviating reading will be located by using the readings given by the sensors and deduction rules stored in the microprocessor of the actuator. In an initial situation, when the valve is in balance state, the readings given by the sensors are stored at least from the control signal, valve position and the difference between the input and output pressure of the actuator. When the operation is continued, the readings given by the sensors are compared with the readings of the initial situation. If the deviations exceed certain limit values and remain there continuously for a certain period of time, a fault message will be given that indicates the location of the fault.
