Struggling with Inaccurate Fuel and Lubricant Measurements? Uncovering the Core Pain Points of High-Viscosity Fluid Metering

Struggling with Inaccurate Fuel and Lubricant Measurements? Uncovering the Core Pain Points of High-Viscosity Fluid Metering

In the industrial production and transportation of heavy oils, resins, polyvinyl alcohol, and various industrial lubricants, precise control of micro-flows and instantaneous flows has consistently posed a major challenge for engineers. Traditional flow meters frequently suffer from severe inaccuracies caused by drastic fluctuations in fluid viscosity, which can ultimately compromise the entire automated control system.

How can you completely resolve the pain points of difficult measurement and high error margins when handling high-viscosity media? This article provides an in-depth analysis of the widely favored EFTEC Gear Flow Meter across industrial sites, guiding you through its working principle, robust technical parameters, and practical application scenarios.

I. Core Working Principle: How Positive Displacement Measurement Achieves "Viscosity Immunity"

As a type of positive displacement flow meter, the core structure of the EFTEC Gear Flow Meter features a pair of precision intermeshing gears functioning as rotors.

• Standard Volume Configuration: The gears and the measuring chamber fit closely together, forming a fixed "standard volume" during operation.

• Measurement Mechanism: Fluid drives the gears to rotate, and the system accurately calculates the flow rate by counting the number of standard volumes passing through within a given time frame.

• Viscosity Immunity: Regardless of how drastically fluid viscosity varies—ranging from low-viscosity water to extremely high-viscosity media exceeding 500,000 cPs+—the measurement accuracy remains constant, fundamentally overcoming the drawback of traditional flow meters being heavily affected by media viscosity.

II. Overview of Key Technical Parameters

To accommodate various rigorous industrial working conditions, this series of flow meters features solid specification configurations:

III. Why Do Industrial Sites Tend to Choose theEFTEC Gear Flow Meter?

1. Superior Measurement Accuracy: Routine reading accuracy reaches 0.5%, with a repeatability of up to 0.03%, ensuring every measured drop of data is reliable and accurate.

2. Unique Pipeline Adaptability: Features a compact laying length and has no strict requirements for straight pipe sections. It can operate stably even when placed close to shut-off valves, pumps, or U-bends, making it exceptionally well-suited for space-constrained installation environments.

3. Outstanding Turndown Ratio: The turndown ratio can reach up to 200:1 to 10:1 (depending on the specific meter size), capable of simultaneously monitoring large flows and micro-flows.

4. Flexible Design and Safety Configurations: Supports pulse, LCD display, 4-20mA composite output, and offers intrinsically safe and explosion-proof (EXD) options; for aggressive chemical reactions, a corrosion-resistant PPS version is also available.

IV. Diverse Industrial Application Fields

Backed by high adaptability to high-viscosity and complex fluids, this product has been widely applied across multiple modern industrial fields:

• Automotive Engineering and Mechanical Manufacturing: Such as gear lubrication monitoring, fuel consumption monitors, diesel injection test benches, and hydraulic pump testing.

• Precision Coating and Chemical Industry: Robotic glue dispensers, electrostatic coating equipment, hot melt adhesive distribution, polyurethane foaming machines, and twin-screw extruders.

• Typical Covered Media: Greases, fuels, oils, gasoline, polyurethane, alcohol, water, adhesives, electrolytes, brake fluids, cavity wax, gear oils, offset printing inks, waxes, paints, polyols, isocyanates, adhesives, resins, silicone, clear varnishes, and solvents.
