To calculate the system mass capacity:
M = V x C
capacity resin resin ex
To calculate the system combined capacity:
C = V x C
capacity resin cor resin ex
To calculate the system volume capacity:
V = M / TH
capacity capacity
or
V = C / TH
capacity capacity
Caution
If a mixing device is set on the valve before meter, TH = TH
Having determined the previous capacity allows the operator to know the service cycle duration.
