Macnaught is a leading name in positive displacement flowmeters, offering versatile and reliable solutions for a wide range of industries, and the oval gear flowmeter is a signature offering.
Pete Graniello, Flowmeter Sales & Business Development at Macnaught Americas, sheds light on what makes their oval gear flowmeters stand out in the market.
"Macnaught's oval gear meters operate on a straightforward yet effective principle," Graniello explains. "Inside each meter are two oval-shaped gears within the flow chamber. Unlike other technologies, this mechanical system focuses purely on volumetric measurement. Regardless of turbulence, vibration, or the physical properties of the fluid, the meter provides accurate readings as long as the gears are turning."
This design eliminates the need for flow conditioning, a requirement for many other flowmeter types, such as turbine or magnetic meters, which depend on laminar flow for accuracy.
The MX Series
Graniello highlights the evolution of Macnaught’s technology. “Oval gear technology has been around since the early 1900s, and our company has been manufacturing these meters since 1964. The latest iteration, our MX Series, builds on decades of refinement to deliver unparalleled versatility and reliability.”
Macnaught MX Meters are engineered to simplify operations without compromising precision. With an immediate response to flow meter inquiries and ready-to-ship inventory, it helps keep processes running smoothly.
"Every MX Meter delivers a standard ±0.5% accuracy with an impressive 0.03% repeatability of flow," he adds, "ensuring consistent and reliable readings."
The Macnaught MX Series is available in sizes ranging from ¼” to 4”, with flow ranges spanning 0.13 GPH to over 320 GPM, making them suitable for a wide variety of industrial applications. "Like all our oval gear flowmeters, the MX series requires no flow conditioning," Graniello emphasizes. "Just place the meter where you need it, and you're ready to go."
Suitable for a Range of Viscosities
One of the key advantages of Macnaught’s flowmeters is their ability to handle a wide range of fluid viscosities, from thin liquids like water to thicker substances like honey, glue, or even cement. Additionally, these meters are particularly suited for applications requiring frequent media changes.
"While other meters may need recalibration or reprogramming to account for changes in density or viscosity," Graniello notes, "Macnaught’s meters continue to perform accurately without any adjustments.
No Calibration Needed
Graniello elaborates, “With our meters, there’s no downtime for recalibration. As long as the new fluid is compatible with the meter’s construction materials, you can switch fluids seamlessly. This is a significant time-saver and a major advantage over competing technologies.”
Graniello notes that this feature has made them highly popular in the agricultural industry, where users often switch between fertilizers, pesticides, and other chemicals. "One of our customers is a multinational agricultural chemical manufacturer producing insecticides, herbicides, and fertilizers. It chose Macnaught’s MX Flowmeters after rigorous beta testing. The meters demonstrated exceptional accuracy and flexibility, meeting the company’s diverse flow rate requirements without the need for recalibration between different chemical recipes. That saved a ton of manhours and avoided a lot of headaches."
Independence from Fluid Conductivity
Another standout feature of Macnaught’s oval gear meters is their independence from fluid conductivity. Graniello says, "Unlike magnetic flowmeters, which require trace metals or minerals in the fluid to function, Macnaught’s mechanical design ensures accurate readings even with non-conductive fluids like deionized water. This versatility makes the meters suitable for a variety of industries, from automotive engine testing to agricultural chemical production, aerospace, oil and gas refineries, and even locomotive fuel efficiency testing."
Flowmeter That Works with Space Constraints
The compact design of Macnaught’s meters further enhances their appeal. "Most models have a footprint no larger than a beer can," Graniello adds, "allowing them to fit into tight spaces where other meters, which often require long straight pipe runs, cannot." This adaptability has made Macnaught a preferred choice for system integrators and manufacturers with space constraints.
