ABSTRACT:
A Coriolis-type mass flow meter for use in sanitary applications. A pair of sensing tubes have their ends rigidly mounted within bores formed within identical inlet and outlet fixtures. The ends of the tubes fit snugly within the bores and are ends brought out flush with the ends of the bores. The flush ends of the tubes are secured to the bores by means of welding. An annular flange is formed about the flush tube ends of the inlet and outlet fixtures to allow easy assembly and removal of the mass flow meter from its associated fluid flow pipeline or conduit. The inlet and outlet fixtures and tubes preferably are formed from a non-reactive, weldable material such as stainless steel. The mounting arrangement of the tubes within the bores of the inlet and outlet fixtures makes it easy to secure the tube ends to the fixtures by means of welding in a readily accessible location. These welds can then be easily smoothed or polished to remove any possible obstructions to fluid flow or hiding places for contamination. This arrangement results in a mass flow meter which is acceptable for sanitary applications, e.g. the measuring of mass flow and/or density of foodstuffs.
