F5: Flow Rate Ratio
Monitoring Liquid Mixture Flow Rate Ratio
•
Basic Operation
The flow rate ratio (%) of input B is displayed on the basis of the
frequency of input A and the frequency of input B.
The measurement value can be obtained using the following
formula:
fa
: Frequency A (Hz)
fb
: Frequency B (Hz)
α
: Prescale value A
β
: Prescale value B
D
: Flow rate ratio (%)
* When

Example:
This example shows the prescale values and the prescale set
values for measuring the flow rate ratio from flow rates (l/min)
using two flow meters (10 l/400 rpm).
Prescale value of Input A (
