Flowmeters commonly used in oil fields are roughly divided into velocity flowmeters, displacement flowmeters and mass flowmeters.
1, flow meter. Through various physical phenomena, the liquid flow rate of the whole pipe flow in the closed pipe is directly measured, and the flow rate of the flowmeter is gradually calculated. It mainly includes turbine flowmeter, vortex flowmeter, ultrasonic flowmeter and so on. It is characterized by high accuracy (up to 0.5), large range, long-distance transmission of traffic signals, and can be networked with computers to achieve centralized management.
2, positive displacement flowmeter. Flowmeters that use mechanical measuring elements to continuously distribute liquid flow to a single volume portion to measure the total volume of liquid are called liquid volumeters. Including elliptical gear flowmeter, Roots flowmeter, waist flowmeter and so on. It is characterized by accuracy up to 0.2, the lower the viscosity, the greater the leakage, the more complex the structure, and the higher the manufacturing accuracy requirements.
3, mass flowmeter. Used to measure the mass or total amount of fluid flowing through the cross section is called a mass flowmeter, and petroleum mass flowmeters are liquid flowmeters, mainly Coriolis force mass flowmeters. It is characterized by adapting to the wide surface of the fluid medium, can directly obtain the mass flow signal, but also can directly measure the temperature and density of the fluid, is an intelligent flow measurement and control instrument.
