Span Calculation example Flow
In the Span Calculation for flow instruction video we assume that a flowmeter generates 20mA at a flow rate of 652.31 USGAL per hour.
As we want to display the total in barrels, the span must be calculated from USGAL / hour into bbl / sec.
Which is: 652.31 / 42 / 3600 = 0.0043142 barrels.
As we want to display the flow rate in barrels per day, the span must be calculated from USGAL / hour into bbl / day.
Which is: 652.31 / 42 x 24 = 372.749 barrels per day.
