FLOW UNIT FOR A CORIOLIS TYPE MASS FLOW METER

摘要

The invention is a flow unit for a Coriolis type mass flow meter, the unit comprising at least one flow tube (1) with an inlet pipe section (2) and an outlet pipe section (3), as well as a rigid body (4) to which an inlet end (2v) of the inlet pipe section (2) and an outlet end (3v) of the outlet pipe section (3) are rigidly secured. The inlet pipe section (2) and the outlet pipe section (3) are parallel with each other, and the flow tube (1) comprises : a first 'S' shaped pipe section (5) having a first arc (5a) connected to an end of the inlet pipe section (2) opposite its inlet end (2v) and being arranged in a way that it curves away from the outlet pipe section (3), and a second arc (5c) curving in a direction opposite to that of the first arc (5a) ; a second 'S' shaped pipe section (6) having a first arc (6a) connected to an end of the outlet pipe section (3) opposite its outlet end (3v) and being arranged in a way that it curves away from the inlet pipe section (2), and a second arc (6c) curving in a direction opposite to that of the first arc (6a) ; and a middle pipe section (7) arranged perpendicularly to the inlet pipe section (2) and the outlet pipe section (3), and connected with the second arc (5c) of the first 'S' shaped pipe section (5) and with the second arc (6c) of the second 'S' shaped pipe section (6).
