M Series mechanical meters hold 1% accuracy with .03% repeatability.
- No flow conditioning required on oval gear and other mechanical models — install meter exactly where you need it, without long pipe runs.
- Built to last — the flow meter line has decades of field history, with many units still running accurately after 30+ years of service.
Macnaught provides professional-grade solutions engineered to deliver reliable, high-precision performance across diverse media types, including Diesel, Oil, Chemicals, Water and more. Built on 10 years of engineering, industrial-grade flow meters handle harsh operating conditions while ensuring accurate readings and exceptional durability.
Types of Flow Meters Available: -
USA-made liquid turbine flow meter range provides cost-effective, high-accuracy measurement, which is specifically optimized for lower-viscosity, clean process fluids like a water flow meter.
As the world’s leading manufacturer of oval gear meters since 1964, these units utilize dual gears to measure true volumetric flow. Positive displacement flow meters (¼"–4") give true volumetric measurement — used across fuel blending, oil dispensing, solvent manufacturing, and general hydraulic flow meter applications.
- MX Hazard Zone Flow Meter
They are specifically designed for Class 1 Division 1 (C1D1) hazardous areas; these flameproof meters provide precise, real-time tracking for highly combustible media like gasoline, solvents, and alcohol. Hazard Zone Flow Meter is used wherever flammable liquids need to be measured, such as fuel terminals and chemical plants.
Simple Safe flow meter needs no electrical energy to power the circuit, making it perfect for remote or unpowered danger zones.
High-precision diesel flow consumption meters are engineered to monitor flow rates and usage patterns across machinery, transport fleets, and stationary engines.
- FCM (Fuel Consumption Meter)
A fuel consumption meter engineered to measure the net fuel burn by tracking both the feed and return lines with extreme precision.
- M-Series Mechanical Register Flow Meter
Heavy-duty positive displacement meters are fitted with robust mechanical registers that do not require external electrical power.
Where These Flow Meters Can Be Used
- Turbine Flow Meter: Best used as a high-precision water flow meter or for measuring clean, low-viscosity process solvents under steady conditions.
- Oval Gear Flow Meter: Perfect for tracking clean, high-viscosity media such as gear oils, adhesives, and thick liquid chemicals.
- MX Hazard Zone Flow Meter: Optimized for chemical manufacturing and fuel depots handling volatile liquids like ethanol, benzene, or methanol.
- Simple Safe Flow Meter: Ideal for remote or unpowered off-grid oil fields, agricultural drone filling stations, or locations where running electrical power lines is restricted.
- Diesel Flow Meter: Used on commercial marine vessels, generators, and heavy earthmoving machinery to track exact diesel consumption.
- FCM: Essential for engine fuel system diagnostics and tracking net fuel consumption on heavy-duty diesel engines.
- M-Series Mechanical Register Flow Meter: Best for mobile fuel-dispensing trucks and fluid-transfer operations where a non-powered, high-visibility register is required.
Flow Meter Frequently Asked Questions (FAQs):-
Q1: What is the difference between a turbine flow meter and a digital flow meter?
A: A turbine flow meter uses a rotating rotor inside a clean stream to calculate velocity, whereas a digital flow meter refers to any flow device—including turbine or oval gear—that outputs a digital pulse or digital display signal.
Q2: Can I use these meters to measure fluids with solids or gases?
A: No. Macnaught MX and MT flow meters are specifically engineered to measure clean process liquids only; they cannot be used with gases or liquids carrying particulate solids.
Q3: How is a hydraulic flow meter different from other liquid meters?
A: A hydraulic flow meter must be built to withstand highly viscous oils and extreme system pressure levels, which is why our high-pressure oval gear series is ideally suited for hydraulic environments.
Q4: Are Macnaught hazardous area flow meters globally certified?
A: Yes. Our MX Hazard Zone and Explosion-Proof meters carry leading global safety approvals and certifications, including FM-US, FM-CA, ATEX, and IECEx.
