Respect to fuel for power generation is becoming increasingly important, leading to sustainable growth of the performance requirements of the devices of its production and transportation.
Particularly high requirements are imposed for compressor stations distribution networks of natural gas. This is due to strong fluctuations in pressure due to the large number of places of entry and places the selection, and incurred the transportation of gas differential pressure and temperature change. To monitor and mitigate these fluctuations serve as pressure compressor stations, which need to consume for this transportable fuel.

Compression of the transported gas is accomplished using compressors powered by electric motors or fed with fuel directly from pipeline gas turbines or gas engines.
Moreover, the effectiveness of this process plays such an important role that, as a rule, and determines the acceptance or rejection of the proposal.
To achieve and evidence efficiency you must monitor and constantly adjust to ever-changing operation many parameters. One of the most important parameters is supplied to the gas compressor drive power. It is difficult to determine value, especially for gas turbines and gas engines, as it depends on a number of different, highly variable process parameters, for example, a certain dimension, depends on the power parameters (pressure, temperature, etc.) and perhaps a more accurate fit to the values determined through simulation of different working conditions.
Drive power is the product of the number of revolutions of the transmission and the attached rotating moment. Accurate measurement of number of revolutions of the problem is not, this value can be considered as given. For torque measurement of various solutions exist that require more detailed consideration. Common to all solutions is that they are based on an rotating torque tightening, i.e. the elastic deformation of the transmission.
