Coriolis measuring transmitter and Coriolis measuring device
The present disclosure relates to a Coriolis measuring transmitter of a Coriolis measuring device for measuring a mass flow or a density of a medium flowing through a pipe, which includes: at least one pair of measuring tubes arranged to oscillate relative to each other, wherein each measuring tube includes a centrally arranged bend, at least one driver and at least two vibration sensors; two guiding devices, each including a fluid chamber with a first opening for connection with the pipe and second openings for each measuring tube for connection with the measuring tubes, wherein the guiding devices are each formed from multiple parts, for example, formed from two parts, wherein a first part forms a pipe connecting part, and wherein at least one second part forms a measuring tube connecting part.
MASS FLOW PRIMARY WITH EXCITER
A method, system, and apparatus for measuring mass flow comprises two tubes for transporting a material; two exciters wherein one of the two exciters is fixedly attached on each of the two tubes configured to induce a vibration in the two tubes; at least two sensors on each of the tubes; a test media flowing through the tube, wherein a phase difference in the tubes is indicative of a mass flow of the test media; and a comparer module operably connected to the at least two sensors on each of the tubes for determining a phase difference of the vibrations in the tubes and determining a mass flow according to the phase difference.
TUBE ARRANGEMENT POLISHED BY FORCED ELECTROLYTIC PLASMA POLISHING IN SECTIONS, IN PARTICULAR A MEASURING TUBE ARRANGEMENT, MEASURING SENSOR WITH SUCH A MEASURING TUBE ARRANGEMENT, AND METHOD FOR PLASMA POLISHING A MEASURING TUBE ARRANGEMENT
A measuring tube arrangement has two support bodies, each with at least one bore, and a measuring tube with a lumen for guiding a medium. The measuring tube has a first end portion and a second end portion which are each connected to one of the support bodies. The tube arrangement has a portion that is polished by forced electrolytic plasma polishing that extends over at least three diameters of the tube. The portion polished by forced electrolytic plasma polishing is followed by an etched portion having a different surface structure than the portion polished by forced electrolytic plasma polishing.
