Methods are for partial updating a graph's layout for nodes and their respective connections when a change to the graph occurs, each node being linked with another node by a connecting line and the connecting line being attached to the respective nodes by using a port on the node. A method of an embodiment includes receiving a user input of an update of the layout. The update includes adding a node or a connecting line, moving a node or a connecting line, or resiting a node. The method of an embodiment further includes positioning the port only on the node affected by the update and on the node connected with the affected one. The method of an embodiment further includes routing the connecting line between the affected node and the node connected.
摘要:
A Coriolis mass flowmeter with a measuring tube through which a medium can flow, at least one actuator and at least one sensor, wherein the measuring tube is bent between its input and output ends into a first winding and a second winding, the first winding and the second winding merging into one another at a transitional section of the measuring tube. The first winding and the second winding run in parallel winding planes and wherein the first winding and the second winding can be excited to oscillation by the actuator and the oscillations detected by the sensor. The Coriolis mass flowmeter is comparably insensitive to the coupling of external oscillations in that oscillating sections of the first winding and the second winding are bent into a V shape that opens in a direction toward the transitional section of the measuring tube.
摘要:
A Coriolis mass flowmeter having at least one measuring tube assembly (1) and at least one mounting assembly (2), wherein the mounting assembly (2) includes at least one bracket (3) mounted on the measuring tube assembly (1) and at least a part of an actuator assembly (4) and/or a sensor assembly (5) supported by the bracket (3) for oscillation generation and/or oscillation compilation so that measuring tube assembly (1) can be excited into oscillation in a reference oscillation plane (X-plane). The Coriolis mass flowmeter oscillation behavior is improved for increasing the quality of measurements by the center of gravity of the mounting assembly (2) being set in the reference oscillation plane.
摘要:
A method for installing and operating a Coriolis mass flowmeter operating having a measuring tube, wherein the measuring tube is excited to vibrate, a phase shift of the vibration of the measuring tube which is dependent on the mass flow of the measuring tube or a corresponding time difference is determined, the temperature of the measuring tube is determined and the corresponding mass flow is calculated using the determined time difference and the determined temperature by means of a computation rule. Highly accurate measurements are possible in that in the computation rule, at least one known theoretical or empirical material temperature dependence influencing the mass flow is taken into account by determining a device-specific temperature dependence of the mass flowmeter influencing the mass flow through a subsequent calibration process and the known theoretical or empirical material temperature dependence and the device-specific temperature dependence are used in determining the mass flow.

A plurality of first insertion grooves are provided along lengthwise directions of the upper and lower corner columns, respectively, and four corner ends of each of spacing members are inserted into the first insertion grooves on the upper and lower corner columns, respectively.
摘要:
A mass flowmeter is provided which operates on the Coriolis principle, having (1) at least four measurement tubes which can oscillate and through which a medium can flow, (2) at least one oscillation generator for excitation of the oscillations of the measurement tube, and (3) at least one oscillation sensor for detection of the excited oscillations of the measurement tubes. The measurement tubes are preferably arranged closely in parallel such that the flow cross section covered by the measurement tubes covers as small an area as possible. The use of four or more compactly arranged measurement tubes advantageously allows for the measurement of a high mass flow rate with measurement tubes having a relatively small cross section and length, resulting in a mass flowmeter having compact length and width dimensions, and which requires only a relatively low energy oscillation generator for excitation of the oscillations of the measurement tubes.
