the instantaneous mixing flow rate in cc/min or mixing
pressure in PSI. This register is primarily used to
reflect that the Mix Unit is on it’s target fluid control
set point. See

multiplied by 100. The ratio consequent is
always 1.
Example : Value = 250 >> A mix ratio of 2.5:1
(Material A to Material B)
• If the current recipe ratio is 0:1 (1K recipe) this
value will be 0.
