Fig. 1. MD classification according to their role in the measurement process and performed functions

As shown in Fig. 1, elementary measuring devices are designed to implement individual direct measurement operations. These include measures, comparison devices and measuring transducers. Each of them, taken separately, cannot perform the measurement operation.
