1. the method for the operation circuit (402) of communicating by letter with coriolis flowmeter (404) comprises the steps:

  • In response to the fluid of the coriolis flowmeter of flowing through, receive transducing signal (432) from coriolis flowmeter;

    Handle the volumetric flow rate speed of this transducing signal with the measurement of the mass flow rate of the measurement of confirming fluid and fluid;

    AndAccording to the volumetric flow rate speed that first of the mass flow rate Fluid Computation of measuring is calculated, comprise that the mass flow rate of removing said measurement with the reference density of fluid principal ingredient is to confirm the volumetric flow rate speed of first calculating;

    Said method is characterised in that further comprising the steps of;

    Receive the temperature signal (434) of expression fluid temperature (F.T.) from coriolis flowmeter (404);

    Handle said temperature signal to confirm the temperature variant density of fluid;

    Thereby the volumetric flow rate speed of the fluid of measuring multiply by this temperature variant density produce a product;

    Thereby the reference density with the fluid principal ingredient is removed the volumetric flow rate speed that this product produces second calculating;

    AndCompare the volumetric flow rate speed of first calculating and the volumetric flow rate speed of second calculating, to confirm the purity of fluid.
