Abstract: A valve of a first container is opened to remove fluid from the first container into a second container, where the output of the first container is arranged to be above a maximum fluid level of the second container. The valve of the first container is closed based on a fluid sensor indicating that a fluid level in the first container is at a first fluid level. A pump is caused to pump the fluid from the second container to the first container via a flow meter. An indication is received after pumping the fluid which causes the pump to stop pumping the fluid from the second container to the first container based on the indication. An amount of fluid pumped into the first container is determined based on the first fluid level and a second fluid level indicated by the fluid sensor. An indication of total fluid volume measured by the flow meter is compared to the amount of fluid pumped. An indication of accuracy of the flow meter is output based on the comparison.
