The work of the FL200AN300+TR regulators installed in the hydraulic fracturing plant No. 4 in Volgograd is considered. The results of calculations of the throughput capacity of pressure regulators are presented. The range of their stable operation is determined on the basis of archival data of the gas flow metering unit. It was revealed that not all outlets provide stable operation of pressure regulators with minimal gas consumption.
