In this paper, we evaluate the water meters available on the market, their advantages and disadvantages are given. The classification of water meters and the assessment of their specific application are given. The main problem at the moment in measuring the flow of water resources is the accuracy of measurement on all flow ranges without a significant increase in the price for the retail sale of the meter. It is shown that the most problematic zone of the range is the minimum and drop rate. The second most important is the maximum flow rate and the accompanying hydraulic shock (in the case when the transition time from zero flow to maximum is negligible). The paper noted that at the moment there are no accounting devices on the market that solve both problems described. It is also shown that it is possible to make the meter more attractive to the consumer with the help of additional (not metrological functions). For example, an important function is the signaling of long-term leaks in the system.
