Abstract: The EMC Chart Integrator, Model 362, is a digital computer based system for translating orifice meter chart records into accurate billing-compatible data on integrated now(chart e.Kiension). average pressure and flow time. It is designed to accommodate American/Barton and Foxboro chaits, as the pens can be mounted so as to pivot in the same geometric paths as the recording pens of these tpes of meters. As an option, the Chart Integrator can be fitted with pens for a third chart geometry if required. The operator places the Chart Integrator pens on the appropriate lines on the orifice chart while applying pressure to the foot control, the chart will begin to rotate. The rotation and motion of the pen:* simulate ihe action of the meter. At the end of the chart the Chart Integrator computes and prints the extension, pressure and flow time for that recording. The operator will then place the chart into the printer and the chart extensiorL, average pressure, flow time and current date will be printed onto the back of the chart for validation. At chart vahdation the extension and the number of charts vahdated are recorded in the Chart Integrators memory as a batch total. This batch total can be printed and cleared upon demand by the operator at any time.
