To the Owner
Please rea
d 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.
Models with a Liquid Crystal Display have an additional LCD instruction manual supplied. If you need
further assistance, contact your local representative
or distributor for advice.
This Flow Meter has incorporated the oval gear principal 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.
With a low pressure drop and high pressure rating
oval gear flow meters are suitable for both gravity
and (in-line) pump applications.
Macnaught offer a comprehensive set web based
support materials to compliment this instruction
manual.

IMPORTANT INFORMATION
OPERATING PRINCIPLE
INSTALLATION PROCEDURE
FLUID COMPATABILITY
Before us
e, confirm the fluid to be used is
compatible with the meter. Refer to Industry
fluid compatibility charts or consult your local
representative for advice.
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.
To prevent damage caused by air purge slowly
fill the meter with fluid.
To reduce pressure build-up turn off the
at the end of each day.
The reed switch can cause inaccurate rate
counts when used with high speed counters.
It is advised that a low speed counter is used or
alternatively a debounce circuit be installed.
AIR PURGE / LINE PRESSURE
STRAINER
Fluid passi
ng 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
sensing elements (Reed and Hall Effect sensors)
located in the Pulser Circuit Board.
The excitation of these switches 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 condi-
tions the Pulse input signal to display volume of fluid
passed. (e.g. Display 1 Litre per for every 36 pulses
1. It is recom
mended 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 flowmeter,
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 Flowmeter 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.
The orientation of the LC display can be changed
by loosening the 4 mounting screws.
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.
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.
REED SWITCH

MAINTENANCE PROCEDURE
Note: Maintenance c
an be carried out to the liquid
crystal displays and pulse output modules without
having to remove or isolate the meter from the process line.
When maintenance to any other part of the meter is
required, the meter must be isolated and the line
pressure released.
Refer to the exploded parts diagram on (see Fig 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
4. Remove the shafts from the meter body.
DISASSEMBLY
REASSEMBLY
1. Before
reassembling check the condition of the
rotors (replace if necessary).
2. Replace the shafts into the meter body.
3. 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.
4. Smear the O-Ring with a light film of grease.
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.
5. Replace the meter cap.
6. Insert the cap head screws and tighten in a
diagonal sequence 1, 5, 7, 3, etc.
(see Meter Torque Ratings, page 15)
7. 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.

The output for the hall effect sensor is NPN (current sinking, open collector). For correct operation, it is advisable to have a pull
-up resistor installed.
The hall effect sensor is equipped with a 1k8Ω pull-up resistor between signal and supply as standard.
This in-built pull-up resistor can be bypassed by moving the jumper pin to the off position if required.
A pull-up resistor of your choosing can be installed between signal and supply, provided the in-built pull-up resistor be bypassed first.
