# Crude Oil Emulsion Phase Flow Meter Skid-Mounted Systems: Design, Applications, and Benefits
## 1. Introduction
In the oil and gas industry, accurate measurement of crude oil flow is critical for production optimization, custody transfer, and fiscal metering. Crude oil often exists as an emulsion—a mixture of oil, water, and sometimes gas—making flow measurement challenging. Traditional single-phase flow meters struggle to provide precise readings in such conditions.
A skid-mounted crude oil emulsion phase flow meter is an integrated solution designed to handle multiphase flows efficiently. These systems combine advanced metering technologies with compact skid-based designs for ease of installation, maintenance, and scalability.

## 2. Understanding Crude Oil Emulsions
2.1 Definition & Composition
Crude oil emulsions consist of:
– Oil (continuous phase) – Hydrocarbon liquids
– Water (dispersed phase) – Produced water or brine
– Gas (optional) – Dissolved or free gas
Emulsions can be:
– Water-in-Oil (W/O) – Water droplets suspended in oil
– Oil-in-Water (O/W) – Oil droplets suspended in water
– Complex emulsions – Multiple phases with solids
2.2 Challenges in Measuring Emulsion Flows
Accurate measurement is difficult due to:
– Variable water cut (% water content)
– Changing viscosity & density
– Gas breakout affecting volumetric readings
– Corrosion & scaling risks
Traditional single-phase meters (e.g., turbine or positive displacement) fail because they assume homogeneous fluids.

## 3. Technologies Used in Emulsion Phase Flow Meters
Several advanced metering technologies are employed:
3.1 Multiphase Flow Meters (MPFMs)
MPFMs measure oil, water, and gas simultaneously without separation:
– Nuclear-based (gamma-ray attenuation)
– Electrical impedance tomography
+ Microwave & capacitance sensors
3.2 Coriolis Flow Meters
Measure mass flow rate based on fluid momentum changes:
– High accuracy (±0.1%)
– Direct density measurement
