Defining instantaneous flow and integrated flow
Flow control in Factory Automation generally falls into one of two types of flow measurement.
"Instantaneous flow" specifies the volume of flow per fixed amount of time. For example, instantaneous flow is equal to 10 L/min when
using 10 liters of flow in the span of 1 minute.
Ex.) A vacuum pump must be supplied with 10 liters of cooling water every minute.
"Integrated flow" specifies the cumulative value of flow used from the start to finish of measurement. For example, when water has
accumulated in a tank for an hour at an instantaneous flow of 100 L/min, the integrated flow is equal to 6000 liters.
Ex.) How much coolant does this grinding machine use in 1 day?
The speedometer of the car is instant (instantaneous), and the trip meter and odometer is cumulative (integrated).
