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.
