The internet of things is an extended and expanded network on the basis of the internet, various information sensing devices are combined with the internet to form a huge network, and the interconnection and intercommunication of people, machines and objects at any time and any place are realized.
The oil well measuring system is generally divided into an oil liquid measuring part and a gas measuring part, and the oil liquid and the gas are respectively measured after gas-liquid separation is carried out on the produced crude oil.
The vortex shedding flowmeter is a flowmeter commonly used in a gas measurement part, and the basic principle is the karman vortex principle, namely: the vortex separation frequency is proportional to the flow velocity. The concrete application is as follows: a cylinder with an approximate isosceles triangle shape is inserted into the measuring pipeline, the axis of the cylinder is perpendicular to the flowing direction of a measured medium, the bottom surface of the cylinder faces the fluid, when the measured medium flows through the cylinder, vortices are alternately generated on two sides of the cylinder and are continuously generated and separated, two rows of vortices which are arranged in a staggered mode are formed on the downstream of the cylinder, and the frequency of vortex separation is in direct proportion to the flow velocity of the medium on the side of the cylinder.
In practice, such problems are encountered: the gas of adopting has certain corrosivity or has impurity, can make the corruption cylinder or adhere to on the bottom surface of cylinder, makes the cylinder warp, and unable law forms the swirl, leads to the inaccurate formation of measurement.
The cylinder is fixed in the measuring tube of the vortex flowmeter, the abrasion or the attachment of impurities is not easy to observe, the oil well is mostly in the field in the countryside, the instrument is inconvenient to disassemble and inspect, and the instrument needs to be calibrated again after being remounted, so the operation can greatly delay the production. Therefore, the vortex shedding flowmeter capable of monitoring the wear degree or preventing sundries from being attached is designed, and is very important for realizing intelligent management of petroleum.
