Patent GB-2237112-A (GB)
Title: Delivery system
Inventor: WALSH GRAHAM
IPC: G08C19/00
Filed: 1990-09-27
Abstract: For controlling the delivery of a consumable fluid [such as oil] from a central control station [C] to individual consumer units [U], a storage tank [T] at each consumer unit is provided with a sensing means [S] which is responsive to the quantity of oil in the tank, and which produces an output signal which is supplied, either directly or indirectly, to the control station [C] at least when the level of oil in the tank falls to a predetermined minimum level. Preferably the output from the sensing device [S] is fed to a smart modem, which, in response to the output indicating the reaching of said minimum level, causes a signal to be delivered via the telephone network to the control station [C]. Alternatively or in addition the control station may interrogate the consumer unit to determine the level of oil in the storage tank, as sensed by the device [S]. Alternative to the use of a telephone line, the possibility of the signal being transmitted from the consumer unit to the control station by radio is contemplated. Oil level in the consumer's tank may be sensed ultrasonically or by a pressure sensor and a temperature alarm may also be provided. <IMAGE>
