Abstract: Turbine meters are well known for their good metering abilities and repeatability, which accounts for their being the most widespread technology for custody transfer all over the world. In France only, 80% of all meters installed on the transmission network are turbines. These good performances are due to their principle of operation and to the choice of good quality mechanical elements, such as a well balanced rotor and bearings. Yet this can turn into a disadvantage, as turbine meters are fragile and can be damaged by solid particles in motion in the fluid, or even by a too severe pressurisation. With the current practice, the defaults inducing metrological errors (misreadings) can be detected only during periodic verifications, when the meter is dismounted and installed on a test bench. In France these verifications are planned every five years. Regularly a certain number of turbine meters is proved to be more or less severely misreading after this five year period. Both customers and gas companies are concerned by misreadings, and the need to improve the confidence in the meters accuracy and reliability is obvious. When it comes to monitoring solutions suited for turbine meters, some exist, like the spin test, but they are not very sensitive and none can avoid a costly and time-consuming dismounting of the meter. That is why the need for a practical and efficient tool for on-line monitoring of turbine meters was the starting point of an internal research program at Gaz de France.
