The FMT-Dc series turbine meter is a unique meter, designed to perform on the highest level of accuracy. The meters comply with all international standards and are approved for custody transfer. The actual flow sensor, TWO cartridges which are exchangable with conventional cartridges used in other turbine meter series, can monitor all kinds of flow effects and monitor the results if connected to flow computer devices. Since these flow computer can analyze any effect, the FMT-Dc is also able to monitor itself and detect any kinds of failures. For example bearing failures, blade failures of dirt in the meter.

When in use, the two independent turbine wheels are not subjected simultaneously to the same flow effects.  This results in minimal differences between the two turbine wheels, which are being detected and diagnosed by the flow computer in a split second. This technique allows for a significant reduction of the uncertainty margin. Also, it opens new possibilities for the future, e.g. remote calibration could be a next step in successfully reducing the measurement uncertainty.

In order to fully exploit the possibilities of two turbine wheels, it has to be established that both turbine wheels operate independently and that occurring influences do not have the same effect at the same time on both turbine wheels.
