Description

Technical Field

[0001] The utility model relates to the technical field of swirl precession flowmeters, in particular to a swirl precession flowmeter which is easy to install. Background Art

[0002] The vortex flowmeter adopts the latest micro-processing technology and has the advantages of powerful functions, wide flow range, simple operation and maintenance, easy installation and use. The main technical indicators have reached the advanced level of similar foreign products and are widely used in various gas measurement in petroleum, chemical, electric power, metallurgy, coal and other industries.

[0003] Chinese patent announcement number CN211373721U proposes a vortex flowmeter, which can seal the flange with the flange of the measured pipe through bolts and nuts during installation, and connect the measuring tube to the measured pipe. When the fluid enters the measuring tube from the measured pipe, it is forced to rotate violently around the axis of the generator through the vortex generator to form a vortex. When the fluid enters the diffusion section, the vortex flow is affected by the backflow and begins to rotate secondary, forming a gyroscopic vortex precession phenomenon. The precession frequency is proportional to the flow rate and is not affected by the physical properties and density of the fluid. The detection element measures the secondary rotation precession frequency of the fluid and knows the flow rate. And every once in a while, it is necessary to open the vent valve to release the gas in the threaded pipe, eliminate the air resistance in the connecting pipe and the threaded pipe, and ensure the measurement accuracy. The vortex flowmeter is designed with a bleed valve at the connection between the sensor installation part and the connecting pipe of the converter, which can be used to regularly bleed air to eliminate the air resistance in the connecting pipe and the threaded pipe. However, the display screen of the above solution is exposed to the air for a long time and is prone to absorb a large amount of dust, making it impossible to clearly see the displayed value on the display screen later. This is relatively troublesome and will affect the service life of the vortex flowmeter, reducing the practicality of the vortex flowmeter that is easy to install. Utility Model Content
