摘要
A mixing system is provided comprising a first mixing tub, a first actuator to control flow of a carrier fluid, a sensor to determine a rate of flow of the fluid, and a second actuator to control flow of a dry material to form a mixture in the first mixing tub. The system further comprises a second mixing tub, a controller, and a weight sensor to determine the weight of the first mixing tub. The controller modulates the second actuator based on the rate of flow of the carrier fluid, based on the weight of the first mixing tub, and based on one of a sensed height of the mixture in the second mixing tub and a weight of the second mixing tub to provide the mixture at least one of at a commanded density and at a commanded flow rate. The mixture may be provided to a well bore to perform a servicing operation.
