1. method that is used to make coriolis flowmeter, described coriolis flowmeter is used to measure the processing material stream of reception, this material stream has the purity of superelevation, do not have the pollution that causes owing to the ion of transferring to described processing material from described coriolis flowmeter, said method comprising the steps of:

  • A driver is fixed on the fluid hose device;

    AndDescribed fluid hose device is connected on the base;

    Sensor device is connected on the described fluid hose device;

    The feature of described method also is following steps;

    Connect described fluid hose device and also comprise the step of the described fluid hose device that use is made by the material that comprises perfluoroalkyl alkoxy copolymer (PFA) or polytetrafluoroethylene (PTFE) to the described step on the described base, little or not from the material of described fluid hose device ion-transfer to described processing material;

    Thereby the described fluid hose device of etching produces the surface that is suitable for connecting with firm discharge meter element;

    AndThe inlet end of described fluid hose device and endpiece are fixed at least one processing connecting portion the feasible ultrapurity flow passage that forms by described flowmeter.
