摘要: Methods may include dispensing an additive from a secondary feeder to a primary feeder: dispensing the additive from the primary feeder to a mixing device: obtaining a primary measurement: obtaining a secondary measurement from the secondary feeder that feeds the primary feeder: comparing the primary measurement and the secondary measurement; and continuing (i-a) dispensing the additive from the primary feeder to the mixing device or (i-b) dispensing the additive from the secondary feeder to the primary feeder: or (ii) when the difference between the primary measurement and the secondary measurement is greater than the selected threshold, halting (ii-a) dispensing the additive from the primary feeder to the mixing device or (ii-b) dispensing the additive from the secondary feeder to the primary feeder, and further recalibrating at least one of the primary feeder or the secondary feeder.
