Turbine meter is one of the measuring tools for natural gas which is commonly used in Indonesia. This is due to the ease of operation, wide measurement range and reliable measurement performance. However, in the operation of the piping network there are several technical things that makes the measurement anomalies. This study raises the case that occurred in the field, there was a decrease in the measurement performance of the meter due to damage to the blade rotor turbine meters in industry with usage ranging from 130-195 m3/hour. From the previous research, there have been similar studies in the case of crude oil. Modeling of the 16-blade rotor meter turbine G-400 was carried out using CFD of the steady-state simulation, isothermal, and realizable k-e turbulence models, varied for a flow rate of 65-650 m3/hour. The results showed that the decrease in the measurement performance of the turbine meter was 2.28% for a flow rate of 130 m3/hour on the damage to 1 turbine meter rotor blade, and decreased gradually as the number of damaged turbine meter rotor blades increased. A decrease in performance appears when 15 blades are broken by 32.52% for a flow rate of 130 m3/hour.
