What Are Macnaught Fuel Meters?

Macnaught Fuel Meters are mechanical or digital measuring devices designed to monitor the volume of compatible fuel passing through a transfer or dispensing system.

Depending on the model, Macnaught uses measurement technologies including:

► Positive displacement
► Nutating disc
► Turbine measurement

These meters can be integrated into compatible fuel-transfer systems using pumps, hoses, filters plus dispensing nozzles.

Depending on the selected product, applications can include:

► Diesel
► Kerosene
► Light oils
► ULP / petrol on specifically approved models
► Coolant on selected models
► Urea/DEF on dedicated meters

Fluid compatibility varies significantly between products.

Never assume every meter within the collection can measure every fuel or workshop fluid.

Why Choose Macnaught Fuel Meters?

Fuel-transfer equipment performs a different job when quantity matters.

Without metering, an operator knows that fuel has moved but may have limited visibility over exactly how much was transferred.

A correctly selected fuel meter provides measurable transfer information directly within the fluid system.

► Measured fuel transfer – monitor how much compatible fuel passes through the system
► Digital options – clear electronic quantity information on relevant models
► Mechanical options – straightforward measurement without relying on a digital display
► Resettable totals – useful for monitoring individual transfer events
► Cumulative totals – track wider fluid throughput
► Multiple measurement technologies – turbine, nutating-disc plus positive-displacement options
► Multiple flow ranges – select around actual pump performance
► 1" connection options – available across several current fuel-meter configurations
► Field calibration – available on selected digital turbine meters
► Pump integration – suitable meters can work with compatible manual or electric fuel-transfer systems

The strongest meter isn't automatically the one with the highest maximum flow.

It is the meter that matches the fluid, pump output, connection, pressure plus normal operating flow.

Product Selection Guide

Choosing the right Macnaught Fuel Meter starts with the fluid.

1. Confirm the fluid being measured

Different meters have different compatibility.

Current applications across the Macnaught range include:

► Diesel
► Kerosene
► Light oils
► Petrol / ULP on specifically approved products
► Coolant on selected digital meters
► Urea/DEF using dedicated compatible equipment

Never select a fuel meter from connection size alone.

Check the exact fluid against the individual meter specification.

2. Choose the correct flow range

The meter needs to operate within its specified flow window.

Current Macnaught examples include:

DM100-01 Mechanical Fuel Meter

► Approximately 3–80LPM
L-DTFM Digital Turbine Diesel Meter
► Approximately 10–100LPM
AMFM Mechanical Diesel Meter
► Approximately 20–120LPM
L-FM25 Mechanical Diesel Meter
► Approximately 20–120LPM
ADTFM Digital Diesel Meter
► Approximately 10–150LPM

The correct range depends on the pump plus real operating conditions.

Don't choose solely around maximum possible flow.

3. Choose mechanical or digital measurement

Mechanical fuel meters can suit:

► Straightforward fuel transfer
► Workshop dispensing
► Agricultural applications
► Mobile fuel systems
► Operators preferring a mechanical register

Relevant Macnaught mechanical products provide resettable batch plus cumulative total information.

Digital fuel meters can suit:

► Clear electronic display
► Transfer quantity monitoring
► Field calibration on selected models
► Digital batch totals
► Cumulative totals
► Portable plus fixed transfer systems

Neither technology is automatically better.

Choose around the working environment plus required information.

4. Choose the correct measuring technology

Macnaught uses multiple meter technologies within the Fuel Meter collection.

Turbine meters

A turbine meter measures flow through movement of an internal turbine.

Relevant models can suit lower-viscosity fluids such as diesel plus kerosene.

Nutating-disc meters

Macnaught uses nutating-disc technology across relevant mechanical diesel meters.

This provides mechanical volumetric measurement without requiring an electronic display.

Positive-displacement meters

The DM100 family uses positive-displacement measurement.

The DM100-01 is specified across approximately 3–80LPM plus can handle compatible petrol, diesel, ULP, kerosene plus light oils.

Select the technology around the fluid plus application rather than assuming all fuel meters operate identically.

5. Check connection size

Several current Macnaught fuel meters use 1" BSP connections.

Examples include:

► L-DTFM – 1" BSP(F)
► L-FM25 – 1" BSP
► AMFM – 1" BSP(F)
► DM100-01 – 1" BSP(F)

The DM100-02 provides an NPT configuration for applications requiring that connection standard.

Before installation, check:

► BSP or NPT
► Male or female connection
► Pump outlet
► Hose size
► Filter connection
► Nozzle configuration
► Existing fittings

Avoid unnecessary adaptor combinations where the correct meter can be selected initially.

6. Check operating pressure

Fuel meters have defined maximum pressure ratings.

Current examples include:

► L-DTFM – approximately 72psi / 5bar
► L-FM25 – approximately 49psi / 3.5bar
► AMFM – approximately 50psi / 3.5bar
► DM100-01 – approximately 50psi / 345kPa

The complete system must remain within the limits of its components.

Check:

► Pump pressure
► Meter rating
► Hose rating
► Filter rating
► Nozzle rating
► Fittings

7. Match the meter to the pump

Fuel-meter performance depends partly on the pump supplying it.

Macnaught fuel systems can use:

► Manual fuel pumps
► 12V electric diesel pumps
► 24V electric diesel pumps
► Higher-flow transfer pumps
► Compatible bulk fuel systems

A pump with free-flow output of 40LPM, for example, should be paired with a meter whose working range comfortably includes the actual system flow after hose, filter plus nozzle restrictions.

8. Consider resettable plus cumulative totals

Different totals serve different purposes.

A resettable batch total can help measure one transfer.

A non-resettable cumulative total can help show longer-term meter throughput.

Potential uses include:

► Individual machine refuelling
► Vehicle transfer quantities
► Daily fuel movement
► Maintenance records
► Equipment usage monitoring
► Bulk fuel accountability

The meter provides volume information.

How that information is recorded or used depends on the business workflow.

Expert Tips for Fuel Meter Selection & Use

Accurate fuel measurement depends on more than installing a meter between two fittings.

► Confirm fluid compatibility first. Diesel compatibility doesn't automatically mean petrol, Urea/DEF or oil compatibility.
► Size around actual flow. Keep normal pump output inside the meter's operating range.
► Check flow direction. Install the meter according to the manufacturer's indicated direction.
► Use the correct thread. BSP plus NPT aren't interchangeable.
► Keep fuel clean. Contamination can affect meters plus downstream equipment.
► Use compatible filtration. Select filtration around the fuel-transfer system requirements.
► Check fittings for leakage. Fuel loss compromises both transfer accuracy plus workplace cleanliness.
► Reset batch totals before transfer. Make sure the displayed quantity belongs to the current job.
► Monitor cumulative totals. Unexpected changes can help identify unusual usage or system issues.
► Calibrate where required. Selected digital meters provide field-calibration capability.
► Inspect hoses plus nozzles. The meter is only one component within the transfer system.
► Stop using damaged equipment. Fuel handling deserves immediate attention when leakage or physical damage appears.

Digital vs Mechanical Fuel Meters

Both meter types provide fuel-volume information but suit different operating preferences.

Digital Fuel Meters

Potential advantages include:

► Electronic quantity display
► Resettable batch information
► Cumulative totals
► Flow-rate display on relevant models
► Field calibration on selected products
► Compact inline installation

The L-DTFM, for example, provides flow-rate display, resettable volume plus non-resettable totalisation.

Mechanical Fuel Meters

Potential advantages include:

► No electronic display dependency
► Straightforward mechanical operation
► Clear resettable batch total
► Long-term cumulative total
► Compatibility with suitable manual plus electric pumps

The L-FM25 uses a nutating-disc mechanism with a four-digit resettable totaliser plus eight-digit non-resettable totaliser.

Choose according to the application rather than display preference alone.

Turbine vs Positive Displacement Fuel Meters

Meter technology affects which applications a product suits.

Turbine Fuel Meters

Turbine meters are particularly suited to compatible low-viscosity fluids.

Macnaught’s L-DTFM is designed for:

► Diesel
► Kerosene
► 10–100LPM flow
► 1" BSP(F) connections
► Digital transfer monitoring

Positive Displacement Fuel Meters

Positive-displacement meters measure discrete fluid volumes.

Macnaught’s DM100-01 supports:

► Petrol
► Diesel
► ULP
► Kerosene
► Light oils
► Approximately 3–80LPM flow
► Approximately ±1% stated accuracy

Where broader fluid compatibility plus lower starting flow matter, a suitable positive-displacement meter can be the stronger choice.

Fuel Meter Accuracy

Accuracy should always be read against the exact meter specification.

Macnaught’s DM100-01, for example, is specified around ±1% of reading.

Meter performance can be influenced by factors including:

► Flow outside the rated range
► Incorrect calibration
► Contamination
► Air within the system
► Incorrect installation
► Fluid incompatibility
► Component wear
► Temperature
► Pump behaviour

Don't treat a displayed number as automatically correct if the system is operating outside the meter's specified conditions.

Diesel Metering From Bulk Tanks

Fuel meters become particularly useful where diesel is dispensed from a shared bulk supply.

A typical transfer system can look like:

Bulk diesel tank → suction equipment → fuel pump → filter → fuel meter → hose → nozzle → vehicle or machine

Metering can provide visibility over how much fuel leaves the storage system during each transfer.

This can support:

► Fleet refuelling
► Farm machinery
► Construction equipment
► Generators
► Service vehicles
► Industrial plant
► Internal fuel records

For powered diesel transfer, the meter needs to match the actual output of the selected pump after system restrictions are considered.

Pairing Fuel Meters With Electric Diesel Pumps

Macnaught’s electric diesel pumps can form a complete transfer setup when combined with compatible filtration plus metering.

A typical portable configuration can include:

Diesel tank → 12V or 24V pump → fuel meter → delivery hose → nozzle

Macnaught’s AFP12M 12V electric diesel pump, for example, provides free flow up to approximately 40LPM plus specifically recommends the ADTFM digital diesel meter for improved transfer measurement.

Meter range should comfortably include the pump's real operating flow.

Fuel Meters vs Macnaught Flow Meters

These categories should remain deliberately separated for both buyers plus search engines.

Choose Macnaught Fuel Meters where the primary requirement is:

► Diesel transfer
► Fuel dispensing
► Farm refuelling
► Fleet refuelling
► Portable fuel systems
► Bulk diesel tanks
► Fuel pump integration
► Mechanical or digital fuel measurement

Choose Macnaught Flow Meters where the primary requirement is:

► Industrial process measurement
► Higher flow ranges
► Industrial fuel plus oil processes
► Specialised process connections
► Pulse integration
► PLC integration
► Chemical measurement
► High-temperature applications
► Industrial positive-displacement measurement

This separation prevents the Fuel Meters collection from competing unnecessarily with Macnaught’s industrial MX plus M-Series flow-meter range.

Fuel Meters vs Inline Oil Meters

Macnaught Fuel Meters should also remain separate from the Inline Meters collection.

Fuel Meters own:

► Diesel
► Fuel transfer
► Kerosene
► Fuel pumps
► Bulk fuel dispensing
► Farm plus fleet refuelling

Inline Meters own:

► Engine oil
► Gear oil
► Hydraulic oil
► Workshop lubrication
► BOP metering
► Oil dispensing systems

This creates a much clearer site architecture around fluid type plus buyer intent.

Urea/DEF Metering

Macnaught’s current Fuel Meter category also includes dedicated digital Urea/DEF metering equipment.

Urea/DEF requires compatible equipment.

Don't transfer Urea/DEF through a meter simply because it is designed for diesel.

A dedicated compatible system should be used across:

► Pump
► Meter
► Hose
► Fittings
► Nozzle
► Storage equipment

Keeping Urea/DEF equipment dedicated also helps reduce contamination risk.

Fuel Meter Installation Considerations

Before installing a Macnaught Fuel Meter, check the entire transfer path.

Review:

► Storage tank
► Pump
► Suction tube or hose
► Filter
► Meter
► Delivery hose
► Nozzle
► Power supply where applicable
► Connection sizes
► Flow direction
► Maximum pressure
► Fluid compatibility

The meter should form part of a correctly matched system rather than being treated as an isolated accessory.
