1.
Where alpha = 45 degree
Flow rate [m/s] = (Flow rate [liter/hour]) * (1hour/3600 sec) * (0.001m³/1 liter) * [1/(π(D/2)²)]
tAB = (L) / [Speed of Sound + Flow Rate * cos(alpha)]
tBA = (L) / [Speed of Sound - Flow Rate * cos(alpha)]
ΔTOF = tAB - tBA
Max Flow Rate Accuracy = (accuracy / 100 ) * ΔTOF
