Problems solved by technology

[0002] At present, the measurement of mass flow is realized by vibration. When a single U-shaped tube is used to measure the fluid in the pipeline, due to the conduction of vibration, the vibration of the electromagnetic vibrator will be transmitted to the surrounding pipeline through the body to cause the pipeline to resonate Thus affecting the stability of the flow signal

Abstract

The invention discloses a quality measuring system for a paralleling U-shaped tube. The system is characterized by comprising the paralleling U-shaped tube, a flow distributor, an electromagnetic vibrator and displacement signal sensors, wherein a flow inlet end of the paralleling U-shaped tube is communicated with an inlet end of the flow distributor; a flow outlet end of the paralleling U-shaped tube is communicated with an outlet end of the flow distributor; the electromagnetic vibrator is mounted at the top of the paralleling U-shaped tube; the quantity of the displacement signal sensors is two; the two displacement signal sensors are respectively mounted on the two sides of the paralleling U-shaped tube. When two paralleling U-shaped tubes are used, the oscillation phases of the two tubes are opposite to each other, so that the tube vibration is cancelled out on the main body part, like the working mode of tuning fork vibration, the surrounding pipeline cannot be influenced by the vibration, the vibration of the U-shaped tubes cannot be influenced and further the stability of the flow signature can be ensured.

Description

technical field [0001] The invention relates to the field of flow measurement, in particular to a parallel U-shaped tube quality measurement system. Background technique [0002] At present, the measurement of mass flow is realized by vibration. When a single U-shaped tube is used to measure the fluid in the pipeline, due to the conduction of vibration, the vibration of the electromagnetic vibrator will be transmitted to the surrounding pipeline through the body to cause the pipeline to resonate Thus affecting the stability of the flow signal. When two U-shaped tubes are used in parallel, the vibration phase of the two tubes is opposite, so that the vibration of the tubes cancels each other in the main body, just like the vibration of the tuning fork, so that the surrounding tubes will not be affected by the vibration, and on the contrary will not affect To the vibration of the U-shaped tube, thus ensuring the stability of the flow signal. Based on this, a parallel U-shape...
