Oil Metering Skid

An oil flow metering skid is a pre-engineered and assembled unit designed to precisely measure the flow rate and other properties of crude oil or refined petroleum products. Similar to gas flow metering skids, they offer a compact, modular solution for accurate and reliable oil flow measurement in various industrial applications.

Components:

· Flow Meter: The heart of the skid, responsible for measuring oil flow rate. Common types include:

o Positive Displacement (PD) Meters: Accurate for various oil viscosities, good repeatability.

o Coriolis Mass Flow Meters: High accuracy, measures mass flow rate directly, suitable for various oil types.

o Turbine Flow Meters: Suitable for cleaner, less viscous oils. (Selection depends on oil type, accuracy requirements, and other factors)

· Strainers: Remove larger particles from the oil stream to protect the flow meter and other instruments.

· Temperature Sensor: Measures oil temperature for flow rate correction and density calculations.

· Pressure Transmitters: Convert oil pressure into an electrical signal for monitoring and recording.

· Flow Computer (Optional): Calculates oil volume or mass flow rate based on meter readings, temperature, and pressure data. May also provide data logging and alarming functionalities.

· Isolation Valves: Allow isolating the flowmeter for maintenance or calibration without interrupting the main oil flow.

· Control Valves (Optional): Used for flow regulation or diverting oil streams within a process.

· Piping and Instrumentation: Connecting all components with proper valves, gauges, and safety features.

· Skid Structure: A sturdy frame that houses and protects all the components, often made from weatherproof steel.

Specifications:

· Oil Type: The specific oil the skid is designed for (e.g., crude oil, diesel, gasoline).

· Flow Rate Range: The range of flow rates the skid can accurately measure.

· Accuracy: Expressed as a percentage of reading (% of reading) or reading plus/minus a fixed value. Typical accuracy for good quality skids is ±0.5% to ±2% of reading.

· Pressure Rating: The maximum pressure the skid and its components can withstand.

· Temperature Rating: The range of temperatures the skid can function within, considering both ambient and oil temperature.

· Output Signal: The electrical signal generated by the skid, typically a 4-20mA current loop or 0-10V voltage signal representing flow rate or other parameters.

· Control System (Optional): Skids can be integrated with a control system for remote monitoring, data logging, and control of valves or other equipment.

· Safety Features: Skids typically include pressure relief valves, leak detection systems, and other safety features to ensure safe operation, especially for flammable liquids like oil.

Benefits of Oil Flow metering Skids:

· Pre-engineered and Packaged: Saves time and engineering costs compared to building a system from scratch.

· Compact and Modular Design: Easy to transport, install, and commission.

· Accurate Measurement: Provides reliable flow rate data for custody transfer, process control, and optimization.

· Weatherproof and Rugged: Designed for harsh outdoor environments.

· Safety Features: Offers built-in safety measures for personnel and equipment protection.

Applications of Oil Flow metering Skids:

· Oil Production and Transportation: Measuring flow rates for custody transfer, pipeline monitoring, and production allocation.

· Oil Refining: Monitoring and controlling oil flow rates within various refinery processes.

· Fuel Oil Delivery: Metering fuel oil for industrial or commercial applications.

· Petrochemical Plants: Measuring flow rates of various oil products within petrochemical processes.

· Tank Farms: Monitoring oil inventory levels and transfer operations.

By understanding these details and specifications, you can select an oil flowmetering skid that meets your specific needs for accurate and reliable oil flow measurement in your industrial application.
