INTRODUCTION
RANGE OVERVIEW
Macnaught’s Positive Displacement Flow Meters are suitable for a wide range of industrial
applications including fuel and oil distribution, corrosive chemical, solvent measurement and high
pressure applications to name a few.
Macnaught offers Positive Displacement Flow Meters featuring Oval Gear technology. The measuring
principle includes two high precision toothed oval gears, which are driven by the flow of the medium and
mesh with each other: in presence of a flow, defined volumes of fluid are transported through the meter
for each rotation of oval gears pair. As the flow rate increases, so does the rotational speed of the rotors.
The number of gear rotations is a measure of the amount of fluid that has passed through the meter;
each rotation is detected by a sensor and the volume is calculated using a conversion factor (K factor).
Figure 1: Macnaught Positive Displacement Flow Meter operation.
A key distinction of positive displacement flow meters is that they offer direct measurement of the
volumetric flow rate. Positive displacement flow meters are frequently specified as they offer high accuracy
and repeatability. They readily provide measurement accuracy within +/-0.5% of the true value.
Additionally, positive displacement flow meters require no power to drive the gear operation with no
special fluid conditioning (e.g. straight lengths of pipe) and are capable of handling high pressure,
large flow variations and plant equipment vibration due to their robust design.
Advantages:
• High accuracy and repeatability
• Suitable for viscous fluids
• Cost-effective
• Accuracy unaffected by changes in viscosity
• Requires minimal maintenance
• Ease of installation
• Exceptional turn-down ratio
Precision engineering and manufacturing methods are used by Macnaught using cutting edge CNC
machining technology and mill certified materials to deliver highly repeatable accuracy and durability.
All critical components are machined in-house with astute quality control monitoring the production
process continuously.*

INTRODUCTION
METER SELECTION GUIDE
Correct specification of the appropriate meter is necessary to achieve desired accuracy and suitable
data output, as well as to ensure safety in each application. While for most applications, the specification
of the appropriate meter will be straightforward, using the specification process outlined below, for
some applications there may be additional technical considerations which need to be assessed on a
case-by-case basis. In all circumstances we recommend that you consult with Macnaught's Technical
Support Team to select the most appropriate meter for your needs
The following steps are provided as general guidelines to assist with correct meter specification.
However, to ensure accuracy of specification in relation to your application, we recommend seeking
expert advice before making the final selection of the appropriate meter. Please note that Macnaught’s
Technical Support Team is available free-of-charge to assist in the specification and identification of a
suitable meter.
Flow Meter Size
Macnaught Positive Displacement Flow Meters are available in a range of sizes that are engineered
to provide high accuracy across a wide turn down ratio. Figure 3 assists in interpreting your process
flow rate, which is an important determinant to the accuracy of your meter. The size of meter should be
selected for maximum coverage for your operating flow rates. As shown in Figure 4, the accuracy of
the meter is optimal near the mid-range of the meter flow range. In some instances the required flow
rates can fall across two meter options, e.g. if the required flow rate is 3 L/min both the MX09 & the
MX12 are suitable, in such cases it is recommended to select the meter where the flow range is within
the upper 50% of the meter’s flow range limits, i.e. the MX09 is preferred.

Macnaught standard ‘single point’ calibration is carried out at mid-flow range where the individual
K-factor is assigned to the meter.
Identifying the correct meter size for the operating flow rates will ensure the longevity of the meter
and deliver optimal accuracy during its operation. For instances where operation is necessary outside
the designated mid flow range of the meter, it is recommended that an optional ‘multi-point’ calibration
is performed which will help ensure maximum accuracy is achieved. We recommend consulting
Macnaught's Technical Support Team before final selection.
Chemical Compatibility
To determine the most appropriate materials combination for each application it is essential that the
wetted components of the meter assembly are confirmed for chemical compatibility. Macnaught meters
are available in standard materials configurations, as shown on the quick reference table below (figure 5):
common fluid types are listed and the recommended materials combination for each of them is indicated.
For a more comprehensive chemical compatibility guide, please refer to Appendix E on page 93.
The chemical compatibility guides referred to above are intended to provide general guidance on
chemical compatibility. It is highly recommended that the data is checked on a case-by-case basis, as
individual process variations in chemical concentration and temperatures from those of the reference
data can influence compatibility. We advise seeking expert advice from Macnaught’s Technical Support
Team to confirm the materials selection.

Temperature & Pressure Rating
INTRODUCTION
All Macnaught flow meters are designed to be completely safe under normal operating conditions.
However, to ensure user’s safety, it is very important to select a flow meter that will operate within the
process pressure and temperature conditions at all times.
Allowances should be made for any potential ‘spikes’ in pressure (e.g. as a result of sudden valve
closures or as the pump initially starts). If the system pressure is expected to reach the meters maximum
rating it may be necessary to incorporate a pressure relief valve into the system. Macnaught's Technical
Support Team is available to provide advice in this regard.
There are a number of factors that influence the pressure and temperature ratings of a flow meter:
Pressure rating:
• Presence of flanged ports causes a reduction of the pressure rating
• Other modifications to the materials properties
Temperature rating:
• Operational parameters such as the limitations of an attached LCD register and batteries
• Coefficient of expansion or
• Other modifications to the materials properties,
When factors combine, the individual effects could amplify and pose a safety risk. We therefore
recommend seeking expert advice from Macnaught’s Technical Support Team before final selection of
the appropriate meter.
Rotor Type
While Macnaught Positive Displacement Flow Meters are capable of processing a very wide range of
fluid viscosities, the viscosity of fluids still need to be considered to aid the selection process. This value
should always be taken at the applications operating temperature and flow rate. Note that typical fluid
technical data sheets are not usually stated at operating conditions, so further research may be required
to determine this information.
In cases where the fluid is non-Newtonian, additional allowances may be required to compensate for
changes to viscosity between static and dynamic situations.
The higher the fluids viscosity the greater the pressure drop it will cause. As shown in Figure 7, the
maximum flow rate will need to be reduced as the viscosity increases. Please contact Macnaught if your
require further assistance. Alternatively, as shown in Figure 6, Macnaught offers High Viscosity (HV)
rotors that have been modified to alleviate this pressure drop and still offer extended flow ranges. As a
general rule if the viscosity is >1000cP it is recommended to use HV rotors, but it is also important to
look for notes on minimum viscosity as this can also affect the meters minimum flow rate.

INTRODUCTION
OPERATING GUIDELINES
While oval gear flow meters provide exceptional accuracy, reliability and a cost effective solution, there
are some considerations for their usage. For example they should not be used to measure fluids with
particles or air pockets in them and adequate filtration needs to be installed upstream of the meter.
Inside the meter are moving components,
so as good practice a routine inspection
may be required. The frequency of the
Figure 8: Recommended installation components for optimal meter operation
OUT
inspection should be based on the
operating conditions; these will include
the maximum flow rate, viscosity and the
fluids lubricating properties. If the meter
FLOWMETER
is used with a lubricating fluid, such as
oil, and is well within the maximum flow
STRAINER
range, then the meter will operate of
many years maintenance free.
IN
Installation Guidelines
1. It is recommended that when setting up pipe work for meter installations a bypass line be
included in the design. This provides the facility for a meter to be removed for maintenance
without interrupting production
2. Use thread sealant on all pipe threads.
3. For pump applications ensure pipe work has the appropriate working pressure rating to match the
pressure output of the pump. Check specified Meter Technical Data section for further details.
4. Install a wire mesh strainer, Y or basket type (refer to pg.82 for Y strainer options) as close as
possible to the inlet side of the meter.
5. For M-series meters ensure that the meter is installed so that the flow of the liquid is in the
direction of the arrows (if applicable) embossed on the meter body.
6. The meter can be installed in any orientation as long as the meter shafts are in a horizontal plane.
(Refer to Figure 9 below for correct installation). The register assembly may be orientated to suit the
individual. Note: Incorrect installation can cause premature wear of meter components.
7. Do not over-tighten meter connections. It is important that after initial installation you fill the line
slowly, high speed air purge could cause damage to the rotors.
8. Test the system for leaks.
9. Check the strainer for swarf or foreign material after the first 1 hour of operation. Check the
strainer for swarf or foreign material periodically, particularly if the flow rate decrease .
