Modern Technologies for Level Measurement

摘要

A huge variety of different technologies exist to measure level: From well established techniques, even simple mechanical ones, up to modern physical solutions with high-tech electronics supported by advanced computer technology.rnThe user has to decide in favour of the best suitable measuring method and choose a specific instrument for his application. In order to assist him in his choice, some manufacturer-independent overviews and decision tables are available. One is the VDI/VDE recommendation 3519 [1] where each technology is described in detail including its limitations. Figure 6 shows an extract of the decision table.
