Medium`s fluid level determining and monitoring method for use in container, involves determining measurement position representing fluid level within group range of echo groups, based on determination procedure

摘要

The method involves determining utility echo signals using an estimation algorithm in an echo function (10) under utilization of the estimation function. The echo signals are formed to echo groups within a determined group range with an upper limit (18) and a lower limit (17). A measurement position representing the fluid level is determined within the group range of the echo groups (26), on the basis of the determination procedure.
