Title: RADAR LEVEL GAUGE
Abstract:
A radar level gauge for determining a filling level of a product in a tank, comprising a volatile high-speed working memory, a first processing unit connected to the volatile high-speed working memory, the first processing unit having an active mode in which the first processing unit is turned on and accesses the working memory, and an inactive mode where the first processing unit is turned off, memory loading functionality, configured to transfer software code from a non-volatile memory into the volatile high-speed working memory, wherein the memory loading functionality is further configured to divide the software code into a plurality of smaller portions, and transfer one such smaller portion at a time. By dividing the software code which is to be transferred into a plurality of smaller portions, the energy required to complete transfer of one such smaller portion can be sufficiently small to allow energy storage capacity of feasible size and cost.
