What kind of flow meter is commonly used in oil fields

Divided into sewage flow meter and gas flow meter
Sewage flowmeters generally use electromagnetic flowmeters.
Instrument accuracy: pipeline type 0.5, 1.0 level; plug-in type 2.5
Measuring medium: various liquid and liquid-solid two-phase fluids with a conductivity greater than 5 μS/cm.
Flow rate range: 0.2~8m/s
Working pressure: 1.6MPa
Ambient temperature: -40 ° C ~ +50 ° C
Medium temperature: PTFE lining ≤180°C
Rubber lining ≤65°C
Shell protection: integrated type: IP65;
Separation type: Sensor IP68 (5 meters underwater, rubber lining only); converter IP65
Output signal: 4 ~ 20mA.DC, load resistance 0 ~ 750Ω
Gas flow measurement is generally selected as a swirling vortex flowmeter (because temperature, pressure, and flow are simultaneously displayed)
The precession vortex flowmeter is compact and consists mainly of a housing, a vortex generator, a sensor (temperature, pressure, flow), a rectifier, a bracket and a converter.
Rotating vortex gas flowmeter conditions
Ambient temperature: -30 degrees Celsius ~ +55 degrees Celsius
Relative temperature: 5%~95%
Medium temperature: -30 degrees Celsius ~ +80 degrees Celsius
Atmospheric pressure: 86kPa~106kPa;
