公开了一种质量流测量装置，包括：流量传感器导管；其中定位有流量传感器导管的壳体；位于壳体外侧的驱动装置，以用于振动流量传感器导管；以及至少一个拾取传感器，其相对于流量传感器导管定位，以便测量在流量传感器导管中由科里奥利力导致的扭曲。电容性拾取传感器包括至少一个电容板，该电容板可连接到第一电势上，并适于位于连接到第二电视上的流量传感器导管附近。电容板相对于流量传感器导管定位，从而在它们之间限定了一个间隙。电容板和流量传感器导管之间的电容由于电容板和流量传感器导管当流量传感器导管振动时的相对远动而变化。 A mass flow measurement device includes a flow sensor tube and a housing having the flow sensor tube situated therein. A drive device is positioned outside the housing for vibrating the flow sensor tube, and at least one pick off sensor is situated relative to the flow sensor tube so as to measure the twist in the flow sensor tube due to Coriolis force. Another mass flow measurement device includes an enclosure having first and second ends. A first sealing member is situated relative to the enclosure first end and a flow body such that the flow body and the first end are connected in a sealed manner. A second sealing member is situated relative to the enclosure second end and a user interface assembly such that the user interface assembly and the second end are connected in a sealed manner.
