INSTRUCTION MANUAL
EXPLOSION/ FLAME PROOF
To the Owner
Please read and retain this instruction manual to assist
you in the operation and maintenance of this product.
This manual contains connection and operating
instructions for the MX-Series Flow Meters with Pulse
Outputs.
Liquid Crystal Displays have an additional instruction
manual supplied. If you need further assistance,
contact your local representative or distributor for
advice
This Flow Meter has incorporated the oval gear
principle into its design. This is proven to be a reliable
and highly accurate method of measuring flow.
Exceptional repeatability and high accuracy over a
wide range of fluid viscosities and flow rates are
features of the oval gear design.
INTRINSICALLY SAFE
With low pressure drop and high pressure ratings,
oval gear flow meters are suitable for gravity and (inline) pump applications.
Macnaught offer a comprehensive set of web based
support materials to compliment this instruction
manual.

IMPORTANT INFORMATION
NOTE
The information contained in this manual relating
to installation is guideline and should be treated
as such.
Please consult all relevant standards and
conditions required by the governing bodies in
area of installation prior to commissioning.
SAFETY BARRIER
The Exia sensors must be installed with an
approved safety barrier
GROUNDING
Improper grounding, poor ventilation, open
flames or sparks can cause a hazardous
condition and result in an explosion or fire and
cause serious injury.
STATIC
If there is static sparking or if you feel an electric
shock while using the meter, stop dispensing
immediately. Identify and correct the problem
before continuing.
NOTE
Equipment must be protected from impact at all
times.
OPERATING PRINCIPLE
Fluid passing through the meter causes the rotors to
turn, as shown below.
One of the rotors (the active rotor) is fitted with
magnets.
The passing of the magnets are picked up by the
electronic sensor.
The excitation of this switch provides a ‘Raw Pulse
Output’ which relates to the K-Factor.
(e.g. KF 36 = 36 pulses per litre of fluid passed)
This Pulse Output Signal can either be fed directly to
an external receiving element (e.g. Data Logger or
PLC) or alternatively to an LC Display which
conditions the Pulse input signal to display volume of
fluid passed. (e.g. Display 1 Litre per for every 36
pulses received)
FLUID COMPATIBILITY
Before use, confirm the fluid to be used is
compatible with the meter. Refer to Industry
fluid compatibility charts or consult your local
representative for advice.
STRAINER
To prevent damage from dirt or foreign matter it
is recommended that a Y or Basket type
mesh strainer be installed as close as
possible to the inlet side of the meter.
When a strainer is installed it should be
regularly inspected and cleaned. Failure to
keep the strainer clean will dramatically effect
flow meter performance.
Contact your local representative for advice.
AIR PURGE / LINE PRESSURE
To prevent damage caused by air purge slowly
fill the meter with fluid.
To reduce pressure build-up turn off the pump
at the end of each day.

Page 4
INSTALLATION PROCEDURE
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 interrupt
ing production. (see figure above)
2. Use a thread sealant on all pipe threads.
Caution: Thread tape must not enter flow meter,
stopping flow meters operation.
3. For pump applications ensure pipe work and
Meter have the appropriate working pressure
rating to match the pressure output of the pump.
Refer to Meter Specifications section for further
details.
4. Install a wire mesh strainer, Y or basket type
as close as possible to the inlet side of the meter.
Meter 1/4” 74 micron / 200 mesh
Meter 1/2”- 2” 250 micron / 60 mesh
Meter 3”- 4” 400 micron / 40 mesh
5. Note: The flow meter can accept flow in any
direction.
6. The meter can be installed in any orientation as
long as the meter shafts are in a horizontal plane.
(Refer to diagram below for correct installation)
.
Note: Incorrect installation can cause premature
wear of meter components.
MAINTENANCE PROCEDURE
Note: Inspection and maintenance of installations
should only be carried out by experienced personnel,
whose training has included instruction on the
various types of protection and installation practices.
DISASSEMBLY
Note: Care should be taken not to drop, damage or
impact equipment due to risk of spark.
Non sparking tools should be used.
Meter should be removed from explosive
atmosphere when maintenance to any part of the
meter is required, the meter must be isolated and the
line pressure released.
Refer to the exploded parts diagram on pg.13-14 for
item numbers.
Note: It is advisable to mark all components with a
marker pen before disassembly, to ensure all the
components are replaced to their correct position
during the reassembly process.
1. Remove the meter cap by loosening the bolts on
the underside of the meter body. (see FIG 1)
2. Remove the O-Ring from the O-Ring groove in the
meter cap.
Wipe clean of grease and store in clean place
3. Remove rotors from the meter body
7. Do not over tighten meter connections.
8. It is important that after initial installation you
fill the line slowly, high speed air purge could
cause damage to the rotors.
9. Test the system for leaks.
Do not continue use if meter is leaking.
10. Check the strainer for swarf or foreign material,
after the first 200 litres check periodically,
particularly if the flow rate is noted to be
decreasing.

MAINTENANCE PROCEDURE
REASSEMBLY
1. Before reassembling check the condition of the
rotors and bushes (replace if necessary).
2. There are two Rotor Types. Active and Neutral.
The Active Rotor is fitted with the magnets. They
can be identified by running a metal object over
the face of the rotor (smooth side)
Caution: The active rotor is always fitted
nearest ‘dimple’ on the meter body
(see FIG 3)
Replace Active Rotor.
Check the smooth side of the rotor is the leading
face when fitting onto the shaft and into the meter
body. (see FIG 2).
Replace Neutral Rotor. Check that the smooth
side of the rotor is the leading face when fitting
onto the shaft. (see FIG 2)
Fit the neutral rotor onto the shafts ensuring that
the rotor pair are at 90 degrees to one another.
(see FIG 3)
Check their operation by turning either of the
rotors. If the rotors are not in mesh correctly,
or do not move freely, remove one of the rotors
and replace correctly at 90 degrees to one
another.
3. Check condition of O-Ring and bolts, replace if
damaged.
Smear the O-Ring with a light film of grease.
Grease applied should meet the following
requirements:
Not harden with age.
Not contain an evaporating solvent.
Not cause corrosion of joint surfaces.
Replace the O-Ring into groove in the meter cap.
The O-Ring will need to be replaced if it has
grown or is damaged in anyway.
4. Replace the meter cap.
5. Insert the cap head screws and tighten in a
diagonal sequence 1, 5, 7, 3, etc.
(see Meter Torque Ratings, page 15)
6. Test the meter by turning the rotors with a finger
or by applying very low air pressure (no more
than a good breath) to one end of the meter,
before returning the meter to service.
Note: When reassembling the meter , all joints
should be thoroughly cleaned and smeared with a
suitable grease to prevent corrosion and to assist
weather-proofing.
Blind bolt holes should be kept clear of grease. Only
non metallic scrapers and non corrosive cleaning
fluids should be used to clean flanges.
