Types of Inline Oil Flow Meters

The flowmeters commonly used to measure oil mainly include the following categories:

1. Turbine Oil Flow Meters
2. Positive Displacement Oil Flow Meters
3. Coriolis Oil Flow Meters
4. Gear Oil Flow Meters
5. Target Flow Meters

Turbine Oil Flow Meters

Turbine flow meters are one of the most common types of inline oil flow meters used for measuring the flow of liquids, including oil. These meters consist of a turbine wheel mounted on bearings within a flow tube. As the oil flows through the tube, it causes the turbine wheel to rotate. The rotation speed is proportional to the flow velocity, which can be measured by a sensor and converted into volumetric flow rate.

Advantages:

• High accuracy (typically within ±0.5% to ±1%)
• Wide flow range
• Fast response time
• Suitable for clean, low-viscosity liquids

Disadvantages:

• Not ideal for high-viscosity fluids or fluids with suspended particles
• Requires regular maintenance to ensure accuracy

Positive Displacement Oil Flow Meters

Positive displacement (PD) flow meters, also known as volumetric flow meters, are designed to measure the flow rate by capturing a specific volume of fluid and counting the number of times this volume is displaced. These meters are suitable for a wide range of fluid types, including oils with varying viscosities. Common types of PD flow meters include oscillating piston, rotary vane, and gear meters.

Advantages:

• High accuracy (±0.1% to ±0.5%)
• Suitable for a wide range of fluid viscosities (especially high viscosity oils)
• Low flow rate capability

Disadvantages:

• Potential for mechanical wear due to moving parts
• May require more frequent maintenance than other meter types

Coriolis Oil Flow Meters

Coriolis flow meters measure the mass flow rate of fluids, making them ideal for applications where mass measurement is critical, such as custody transfer and chemical mixing. These meters utilize the Coriolis effect, which causes the fluid to exert a force on a vibrating tube, resulting in a measurable phase shift. The mass flow rate can be calculated by analyzing this phase shift.

Advantages:

• Direct mass flow measurement
• High accuracy (±0.1% to ±0.2%)
• Suitable for a wide range of fluid viscosities and densities
• No moving parts, resulting in low maintenance requirements

Disadvantages:

• Higher initial cost compared to other meter types
• Sensitive to external vibrations and temperature fluctuations

Gear Oil Flow Meters

Gear oil flow meters use a pair of intermeshing gears to measure the flow rate of oil. As the oil flows through the meter, it causes the gears to rotate, and the number of rotations can be used to calculate the flow rate. Gear flow meters Gear flow meters are suitable for a wide range of fluid viscosities, making them versatile and effective for various oil types.

Advantages:

• High accuracy (±0.5% to ±1%)
• Capable of handling high-viscosity fluids
• Low pressure drop
• Suitable for bidirectional flow measurement

Disadvantages:

• Moving parts can lead to mechanical wear and increased maintenance
• Not ideal for fluids with suspended particles

Target Flow Meters

Target flow meters, also known as drag force flow meters or solid-state flow meters, measure the flow rate of fluids, including oils, by detecting the drag force exerted on a target or sensor placed in the flow stream. The force exerted on the target is directly proportional to the flow rate, allowing for accurate flow rate calculations. Target flow meters can be said to be Inline Oil Flow Meters specially designed to deal with extreme working conditions. Target flow meters are suitable for a wide range of fluid types and can handle varying viscosities and densities.

Advantages:

• High accuracy (±0.5% to ±1% of reading)
• Suitable for high-viscosity fluids
• No moving parts, resulting in low maintenance requirements
• Capable of handling dirty or corrosive fluids
• Resistant to wear and tear

Disadvantages:

• Can cause a pressure drop due to the target obstruction in the flow stream
• Sensitive to changes in fluid properties, such as viscosity and density
• May require periodic cleaning of the target to maintain accuracy
