The extraction of metals and subsequent processing into finished product takes place in series of various operations which demand the usage of much energy. Saving energy is the main purpose of the present industry investigations. Aluminium industry is one the greatest energy consumers with 13-17 kWh/kg of Al and low energy efficiency of 40-50 %. At the same time every day researchers strive to increase current output and reduce energy consumption of aluminium pots for primary aluminium used in various applications. In the present work, the attention is given to the energy efficiency. In particular, it is considered that titanium diboride is used in cathode pot lining to prolong cell’s life cycle, to reduce the electric consumption of cell series due to the voltage drop and reducing anode to cathode distance.

In modern technological processes, a large role is played by measurements of technical parameters. The total number of industrial enterprises is constantly monitored by regulatory authorities for the use of water resources. Mostly it was not possible to measure most of the existing pressure-free flows recently, but with the advent of equipment on the metrology market that could measure the speed and level at the same time, the situation changed radically. It makes sense to consider in detail two measurement methods that are currently used in more than 90 % of cases – the acoustic (non-contact) method and the two-channel Doppler method which metrological standards of these methods were compared.
