Introduction
The intelligent natural gas flow meter (also called gas turbine flow meter) integrates temperature, pressure and flow measurement functions. It is an ideal instrument for gas measurement of various gases in petroleum, chemical, electric power, metallurgy and other sectors and industrial fields, such as natural gas, city gas, methane, butane, air, nitrogen, gas pressure regulating stations and custody transfer etc.
Why temperature and pressure compensation is needed for natural gas flow measurement?
Temperature and pressure compensation is a technology that uses built-in temperature sensors, adopts temperature and pressure compensation to correct the measurement volume value to the standard volume value (P=101.325Kpa, T= 20℃). So that to achieve accurate gas flow measurement.
Generally speaking, because the density of the gas is greatly affected by changes in temperature and pressure, it is susceptible to temperature and pressure to deviate from the ideal working state, resulting in large errors in the measurement results. Therefore, in order to ensure accuracy, temperature and pressure compensation is required.
