When it comes to industrial flow measurement, selecting the right technology is crucial for accuracy, efficiency, and long-term performance.
Two of the most widely used technologies today are the Magnetic Flow Meter (Mag Meter) and the Oval Gear Flow Meter. While each has its place in various applications, the Macnaught MX Oval Gear Flow Meter consistently outperforms when it comes to clean process fluids, precision, and speed of delivery.
In this blog, we’ll break down the key differences between magnetic flow meter and oval gear flow meters and explain why Macnaught Canad is the trusted source for engineers and facility managers across North America.
Understanding the Basics: Magnetic Flow Meters vs Oval Gear Flow Meters
Magnetic Flow Meters (Mag Meters)
Magnetic flow meters operate based on Faraday’s Law of Electromagnetic Induction, which means they only work with conductive fluids (usually water-based). They are commonly used in wastewater, slurries, and corrosive liquids.
Pros:
- No moving parts
- Low maintenance
- Suitable for conductive fluids
Cons:
- Not suitable for non-conductive fluids like oils, hydrocarbons, or solvents
- Requires grounding and careful installation
- Limited accuracy with low-viscosity, clean process fluids
- Flow Conditioning - Average Upstream requires 5 pipe diameters
- Downstream requires 2-3 pipe diameters
Oval Gear Flow Meters
Oval gear meters use positive displacement technology, with intermeshing gears that rotate as fluid passes through. This makes them ideal for measuring clean, viscous, and non-conductive fluids with exceptional precision.
Pros:
- Accurate measurement of both low- and high-viscosity fluids
- Works with clean, non-conductive liquids like oils, fuels, and chemicals
- No need for conductivity or flow conditioning
- Ideal for batching and dispensing
- No Flow Conditioning Required – perfect for tight spaces
Cons:
- Contains moving parts (though durable)
- May not be ideal for slurries or fluids with particulate

Why Choose Macnaught’s MX Oval Gear Flow Meter?
When it comes to clean process fluids, the Macnaught MX Series stands above the competition. Here's why:
✅ Superior Accuracy and Reliability
The Macnaught MX Oval Gear Flow Meter delivers .5% Volumetric Accuracy with .03% Repeatability
Inline sizes from 1/4" to 4" with Flow Ranges from .13GPH to 600GPM+
✅ Ideal for Clean Fluids
Unlike magnetic flow meters which require conductive fluids, Macnaught Flowmeters measure most clean process fluids including;
Oils, Fuels, Solvents, Glycols, High Viscosity Medias, Water and a wide range of other fluid chemistries.
✅ No Flow Conditioning and Install Flexibility
Macnaught Meters require zero upstream or downstream pipe lengths. Ideal for OEM and Industrial applications with tight install spaces
in mind. Meters come standard with FNPT connections, easily add fittings as needed including Flanges of any type, Cam Lock, NPT, Elbows or other.
✅ Durable, Low-Maintenance Design
The Macnaught MX features rugged construction with a modular, repairable design—reducing downtime and long-term maintenance costs. Built to last, these meters are CNC-machined from solid aluminum or stainless steel for extreme reliability in industrial environments.
✅ Huge Inventory Ready to Ship
Time is money. That’s why Macnaught Canada stocks one of the largest inventories of MX Oval Gear Flow Meters in North America, with fast turnaround times. When your operation can’t afford delays, you can count on Macnaught to deliver—quickly and reliably.
✅ Backed by Industry-Leading Support
With over 75 years of engineering excellence and a reputation for quality, Macnaught offers unparalleled technical support and service to help customers get the most from their flow measurement systems.
Applications Where the Macnaught MX Oval Gear Flow Meter Shines
- Diesel Fuel Measurement and Consumption
- Hazard Rated Fluids C1D1, C1D2, Simple Safe
- Batching Applications
- Oil and Lubrication Metering
- Glycols of all types
- Epoxies and Adhesives
If you work with clean process fluids, the Macnaught MX should be your flow meter of choice.
Make the Smart Switch
While magnetic flow meters remain useful for specific applications involving conductive fluids, they fall short when it comes to precision measurement of clean, non-conductive process fluids. The Macnaught MX Oval Gear Flow Meter offers the accuracy, durability, and flexibility needed for today’s demanding industries—with inventory in stock and ready to ship from Macnaught Canada.
Don’t wait weeks for a meter that might not fit your needs. Choose Macnaught MX and experience fast shipping, high performance, and unmatched quality.
