The existing algorithm for determining mass flow in gas production and transportation systems from output pressure measurements is extended to the case where the internal section of the tube changes with time and is also to be determined in the course of solving the general problem. It is proposed to use this algorithm to determine the presence of hydrates in such systems. An example of determining the presence of hydrates in a main gas pipeline section in permafrost is considered.
