Tab. 16 Characteristic curve for the analogue output
Example calculations for calculating the maximum occurring characteristic curve deviation:
In the display of SFAM-1000U, a measurement value of 600 l/min will be shown for the flow rate.
Howlarge can the actual, true flow rate that flows through the sensor be?
