摘要： A flowmeter having a case enclosing a single straight tube surrounded by a balance bar. The balance bar ends are coupled by means of a brace bar to the flow tube as well as by case connect links to the inner wall of the case. The flow tube ends are coupled to end flanges by means of a raised element having a center opening for sealably receiving the flow tube terminus. The flow tube projects beyond the case end and is sealably coupled to a cone connect element in the case end. A void is defined by the space between the flow tube outer surface and the inner surface of the cone connect element and the end flanges to minimize the surface area of the flow tube that is affected by the weld between the case end and raised element of the end flanges. The case connect links contain out of plane bends to accommodate a change in the effective diameter of the case and the balance bar with respect to each other due to changing thermal conditions. Another embodiment of the invention includes a flowmeter without the end flanges. The flow tube ends project beyond the case ends while being sealably coupled to the cone connect element in the case ends. The flowmeter may be manufactured, tested, and balanced and stored without a flange. The flowmeter is stored in this condition until its commercial use is imminent at which time it is fitted with the appropriate end flange required by the end user.

摘要： A system enclosing a Coriolis flowmeter in a explosion proof housing. The explosion proof housing is structured in a way that the housing can withstand an explosion of volatile material inside the housing. The explosion proof housing prevents sparks and heat inside the housing from igniting volatile material outside the housing. Any gaps or openings in the explosion proof housing provide a flame path of sufficient length to cool a flame or hot material escaping from the housing. The use of the secondary housing as an explosion proof compartment allows the use of a driver having greater power as well as conventional leads inside the housing.

摘要： An apparatus for measuring the flow rate of a fluid flowing through a minimal flow pipeline with a Coriolis effect mass flowmeter. The flowmeter has a single flow tube with two loops. The loops are connected by a cross-over section. A driver oscillates the loops and the phase difference between the ends of the loops is measured. The measured phase difference is then used to find the flow rate of the fluid. The flow tube is fixedly attached to an anchor which is, in turn, attached to a housing. The anchor separate the vibrating, dynamic portion of the flowmeter from the non-vibrating portion of the flowmeter.

摘要： An apparatus for measuring the flow rate of a fluid flowing through a minimal flow pipeline with a Coriolis effect mass flowmeter. The flowmeter has a single flow tube with two loops. The loops are connected by a cross-over section and are adapted to be vibrated in phase opposition by a driver. The phase difference between the ends of the vibrating loops is measured. The measured phase difference is used to find the flow rate of the fluid. The flow tube is fixably attached to an anchor which is, in turn, attached to a housing. The anchor separates the vibrating dynamic portion of the flowmeter from the non-vibrating portion of the flowmeter.
