1. A method comprising:
coupling a metering device to a storage container, wherein the metering device comprises one or more pockets;
loading the storage container with a first amount of a first proppant;
calibrating the metering device for the first proppant by dispensing a second amount of the first proppant via the metering device at two or more speeds, wherein the calibrating is based at least in part on a number of pulses emitted by an encoder coupled to the metering device; and
operating the metering device for the first proppant based on the calibrating step.
