Flow control apparatus for liquid delivery system
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.
