At ManuFlo, a leading Australian company specializing in manufacturing, selling, and servicing cutting-edge flow meters, we believe that positive displacement flowmeters (PD meters) are the ideal solution for accurately measuring clean liquids across various applications. In this guide, we will explain how PD flowmeters work, explore the different technologies available, highlight their key benefits, and showcase their diverse applications.
How Do Positive Displacement Flowmeters Work?
Positive displacement flowmeters measure fluid in precise volumes. As the fluid enters a chamber, it gets sealed, and either an electronic pulse is produced or gears drive a register to track the volume as it exits. This method ensures highly accurate volumetric measurements, similar to filling a bucket to the brim multiple times and calculating the total volume.
Types of Positive Displacement Flowmeter Technologies
At ManuFlo, we offer various PD flowmeters, each operating on the positive displacement principle. Our selection includes:
- Oval gear meters
- Nutating disc meters
- Spur gear meters
- Variable area flow meters
- Screw meters
- Oscillating piston meters
- Helical gear meters
- Rotary vane meters
These flowmeters use precisely engineered moving blades or gears against uniform chamber walls, ensuring accurate and consistent measurements.
Key Benefits of Using Positive Displacement Flowmeters
Positive displacement flowmeters provide several advantages over other flow measurement methods, making them a preferred choice for many industries.
- Accurate Measurement Across Viscosities: PD meters handle liquids with varying viscosities, including those affected by temperature changes, ensuring consistent accuracy.
- Operation at Low Flows: These meters excel in measuring low flows of highly viscous fluids like oils and greases, without sacrificing accuracy.
- No Flow Conditioning Required: Unlike other meters, PD flowmeters do not need straight pipe lengths for accurate measurements, saving installation space.
- Versatile Design: PD meters can operate with voltage pulse signals or mechanical registers, making them suitable for remote or low-maintenance sites.
- Durable and Low-Maintenance: Engineered for long-term performance, PD meters withstand noise, vibration, and require minimal maintenance.
- High Accuracy and Turndown Ratio: With a wide turndown ratio and exceptional accuracy, PD meters offer cost-effective solutions for varied applications.
Applications of Positive Displacement Flowmeters
ManuFlo’s positive displacement flowmeters are versatile and suitable for a wide range of industries:
- Inventory Management: Ideal for managing chemicals, from detergents to caustic solutions, PD meters ensure precise measurements.
- Fuel Consumption Monitoring: Used in mining and construction sites to monitor diesel generator fuel consumption accurately.
- Proportional Blending: Small oval gear meters are commonly used in fuel terminals to blend additives like anti-icing agents and combustion modifiers.
- Viscous Fluid Applications: Perfect for clean, viscous liquids like oils, greases, and fuels that lubricate the moving parts.
- Low Viscosity Fluids: PD meters also work well with low viscosity liquids such as water, alcohol, and solvents.
- Food Processing: Ideal for dosing exact volumes of edible oils, honey, molasses, and chocolate in food production processes.
