Abstract
Abstract A host processor (1 A) stores a preset delay time data (T), corresponding to the time taken from the initiation of a delivery operation for liquid to start being delivered from a delivery nozzle (28). During delivery,the amount of liquid delivered is measured by a sub-processor (1B) using flow-rate pulses. When a delivery nozzle (28) is activated, it sends a signal to the sub-processor (1 B). The sub-processor then obtains the preset delay time data (T) from the host processor and does not count flow-rate pulses during the delay time. This improves the sub-processor's measurement of the liquid delivery, since it avoids incorrectly treating delivery as occurring before liquid has reached the nozzle.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
81 words
A flow-rate measurement control device for the refuel control system, which is capable of inhibiting counting operations against the flow-rate pulses during the initial period of a refuel operation in conjunction with a specific time data (T) stored in memory (34) comprising; a refuel unit (2); a flow-rate pulse generator (27) incorporated in the refuel unit (2); the memory (34) for storing the presetable time data; and a counter for counting the flow-rate pulses generated by the flow-rate pulse generator (27).
Claim 2
Dependent Claim
81 words
A flow-rate measurement control device for the refuel control system, which is capable of inhibiting counting operations against the flow-rate pulses during the initial period of a refuel operation in conjunction with a specific time data (T) stored in memory (34) comprising; a refuel unit (2); a flow-rate pulse generator (27) incorporated in the refuel unit (2); the memory (34) for storing the presetable time data; and a counter for counting the flow-rate pulses generated by the flow-rate pulse generator (27).
Claim 3
Dependent Claim
50 words
Flow control apparatus for a liquid delivering system, in which flow is measured during liquid delivery by use of pulses generated by a pulse generator (27) characterised in that following the initiation of a liquid delivery operation the said pulses are ignored in the flow measurement for a preset period.
Claim 4
Dependent Claim
50 words
Flow control apparatus for a liquid delivering system, in which flow is measured during liquid delivery by use of pulses generated by a pulse generator (27) characterised in that following the initiation of a liquid delivery operation the said pulses are ignored in the flow measurement for a preset period.
Claim 5
Dependent Claim
16 words
Flow control apparatus according to claim 2 which 'has means for altering the said preset period.
Claim 6
Dependent Claim
40 words
Flow control apparatus according to claim 2 or claim 3 in which the said measurement of flow is carried out by data processing means (1), the said preset period being stored in a memory of the data processing means (1).
Claim 7
Dependent Claim
90 words
Flow control apparatus according to claim 4 in which the said data processing means (1) comprises a control processor (1A) and an operation processor (1B), the said preset period being stored in a memory (34) of the control processor (1A), the operation processor (1B) obtaining the value of the preset period from the control processor (1A) on initiation of a liquid delivery operation and receiving the said pulses during the liquid delivery operation, the operation processor (1B) counting said pulses received by it after the expiry of the preset period.
