In oil extraction, different flowmeters will be used according to the actual situation, so today I will introduce the working principle and 

characteristics of oilfield flow meters

1. Velocity flowmeter. The flow meter that directly measures the liquid flow rate of the full pipe flow in a closed pipe through various physical 

phenomena, and further calculates the flow rate is a velocity flow meter. It mainly includes turbine flow meter, vortex flow meter, ultrasonic 

flowmeter, etc. It is characterized by high precision (up to 0.5 grade), large range, long-distance transmission of flow signals, and networking 

with computers to achieve centralized management.

2. Positive displacement flowmeter. A flow meter that uses a mechanical measuring element to continuously dispense the flow of liquid into

 individual volumetric portions to measure the total volume of the liquid is known as a liquid volume flow meter. Including oval gear flow meter, 

Roots flowmeter, waist wheel flowmeter, etc. Its characteristic is that the precision can reach 0.2 grade, the lower the viscosity, the greater the 

leakage, the more complicated structure, and the higher manufacturing precision requirement.

3. Mass flow meter. The mass flowmeter used to measure the mass or total amount of fluid flowing through a certain cross section is called a

 mass flowmeter, and the mass flowmeter for petroleum is a liquid flowmeter, mainly a Coriolis force mass flowmeter. It is characterized by 

adapting to a wide fluid medium surface, can directly obtain the mass flow signal, and can directly measure the temperature and density of the 

fluid. It is an intelligent flow measurement and control instrument.
