Definitions
- the present invention relates to water metering systems.
- the present invention provides a water metering system comprising meter means for measuring the quantity of water supplied through a pipe, valve means for shutting off the water supply, a reader for reading credit units from a credit unit storage means, a processor for controlling the valve means in response to information received by the processor from the reader and from the meter and means for supplying -power to the reader, the processor and the valve means.
- meter means for measuring the quantity of water supplied through a pipe
- valve means for shutting off the water supply
- a reader for reading credit units from a credit unit storage means
- a processor for controlling the valve means in response to information received by the processor from the reader and from the meter and means for supplying -power to the reader, the processor and the valve means.
- the processor automatically varies the amount of water supplied per unit credit in response to a predetermined type of use.
- the processor may vary the amount of water supplied per unit credit in response to the time of usage of water. This enables a higher tariff to be charged during peak periods of water usage, for example at certain times of day or on certain days of the week, so that users are encouraged to transfer a portion of their water consump ⁇ tion to periods of lesser usage and/or restrict their usage during periods of heavy demand.
- the processor may vary the amount of water supplied per unit credit in response to the amount of water supplied per unit time. This enables the tariff to be varied according to the volume of water used over a predetermined time period, for example per hour or per day. Thus, users who consume a large quantity of water over only a few hours or a few days can be charged at a higher tariff.
- the means for supplying power preferably includes a battery, for example a long life battery,
- the processor in response to a predetermined flow rate of water the processor is arranged automatically to shut the valve.
- the processor in response to a predetermined flow rate of water the processor is arranged automatically to shut the valve.
- the reader is preferably a card reader into which a credit unit storage card can be inserted.
- the system may be sealed in an electronically secure manner in a housing so that interference with the housing can be detected by electronic enquiry from a remote position.
- the present invention further provides a card for use in a system according to the invention the card having two discrete regions on which credit units are stored the card being so arranged that on deletion of all the units in one region the card must be removed from the reader and reinserted in a different orientation in order for the units in the second region to be used.
- the card may for example be arranged such that the major part of the credit units are in a first region at one end of the card and credit units for a period of only a few days typical usage are in a second region at the other end of the card.
- a meter 1 measures the water flow in a water supply pipe 2, the information being passed to a processor 3 as represented by dotted line 4.
- the meter may be for example a standard turbine metering unit fitted with a reed switch as used in known remote reading installations.
- a card reader 5 is arranged to pass information read from a credit unit storage card 5a to the processor 3, as represented by dotted line 6.
- a control valve 7 is sited in the pipe 2 and is controlled by the processor in response to the information received from the card reader relating to the available credit and from the meter relating to the amount of water used.
- a power pack 8 containing a battery provides power to the card reader 5, processor 3 and control valve 7 as represented by the solid lines.
- the processor 3 may be preset to adjust the amount of water supplied per unit credit according to any selected variable factor, for example in response to the time of supply or the amount of consumption.
- the reader determines whether there is credit available and passes this information to the processor. Assuming that credit is available, the valve 7 is opened and water passing through the meter is measured by the meter 1. The meter is monitored by the processor 3. The amount of water which is to be supplied per unit credit as determined on the basis of the above- mentioned factor is calculated by the processor 3. When the last credit unit readable on the card has been used up, the processor responds by shutting the valve.
- the card When a card according to the invention having two discrete credit unit storage regions is used, the card can be turned around after the first region is used up, the second region providing sufficient credit for a few more days water supply, thus alerting the user to the fact that almost all of the credit units have been used.
- a customer purchases a given number of credit units in advance, preferably in the form of credit units stored on a credit unit storage card. In this way, it is possible to ensure that water used by the customer is paid for in advance.

Abstract
Dans un système de compteur d'eau, la quantité d'eau passant dans un tube (2) est contrôlée par un compteur (1), et une vanne (7) sert à fermer l'alimentation en eau dans le tube (2). Un processeur (3) commande la vanne (7) en réponse à des informations provenant d'un lecteur (5) affichant les unités de crédit tirées d'un moyen de stockage d'unités de crédit et dudit compteur (1). Lors de l'utilisation du système, la quantité d'eau passant dans le tube (2) est commandée en fonction de la disponibilité d'unités de crédit dans le moyen de stockage d'unités de crédit.
