A device () for determining temperature and a measuring arrangement for determining flow that allows for a secure attachment on an object. The device has a measuring element () with a temperature-dependent electric resistance value. The measuring element () is surrounded by a thermally conductive fixing element () and is encompassed by a retaining bracket ().

Device for determining temperature as well as measuring arrangement for determining flow

A Coriolis mass flowmeter having two measuring tubes, wherein two neighboring oscillation node plates are provided on one end of the measuring tube that connect the two measuring tubes to one another and wherein the angle between the planes of both oscillation node plates is determined in such a manner that the vibration of the measuring tubes is minimal up to a predetermined driving force. A method of producing the flowmeter is also disclosed.

A Coriolis mass flowmeter having a measuring tube that can be excited to oscillation and a magnet assembly () serving to generate oscillations and/or to receive oscillations. The magnet assembly () includes at least one permanent magnet () and a magnet holder () holding the permanent magnet (). The Coriolis mass flowmeter that has a mounting for the permanent magnet, which can withstand long-term oscillation stress and can reliably protect the permanent magnet is implemented by the magnet holder () consisting of nonmagnetic metal such as stainless steel.

A Coriolis mass flowmeter has exactly two measuring tubes that can be excited to oscillation and a housing. An end connection plate from a pipe to both measuring tubes is provided on each end of the measuring tube, and these the end connection plates are attached to one another by means of a reinforcing bridge that is separate from the housing.

A Coriolis mass flowmeter that incorporates a straight Coriolis measuring tube, two straight connecting pipes, at least one oscillator stimulating the tube, a measuring sensor associated with the tube and a compensating cylinder, where the tube is positioned within the cylinder, the two end sections of the cylinder are solidly connected to the respective end sections of the tube, the tube transitions with either end section into a connecting pipe, the connecting pipes extending outside the compensating cylinder, and by means of mounting flanges provided on the external ends of the connecting pipes, the mass flowmeter can be installed in a pipeline system. Each connecting pipe meets the requirements of the formulawhere M is the mass of the cylinder, f is the natural frequency of the water-filled tube, e is the modulus of elasticity of the connecting pipes, i is the geometric moment of inertia of the connecting pipes and l is the length of the connecting pipes.

Mass flowmeter

A method for mounting a metal body on an essentially straight measuring tube, made of titanium or zirconium, of a Coriolis mass flowmeter. The method ensures secure retention of the metal body on the measuring tube even through very extended operation of the Coriolis mass flowmeter, in that the metal body is shrink-mounted on the measuring tube.
