Automated blender bucket testing and calibration

A pump control system, comprising:

• an additive pump, the additive pump being fluidly coupled to a component of a hydraulic fracturing system;
• an additive container, the additive container configured to provide an additive to the additive pump;
• a diversion system, arranged within a flow path between the additive pump and the component of the hydraulic fracturing system, comprising:
• a first separate flow path coupled to the component of the hydraulic fracturing system, and
• a second separate flow path, wherein at least a first portion of the additive entering the diversion system is directed along the first separate flow path and at least a second portion of the additive entering the diversion system is directed along the second separate flow path;
• and
• a calibration system configured to receive at least the second portion of the additive via the second separate flow path, the calibration system adapted to adjust one or more operational parameters of the additive pump responsive to an evaluation of a flow parameter of at least the second portion of the additive.
