IMPORTANT INFORMATION (READ CAREFULLY)
FLUID COMPATIBILITY: Before use, confirm the fluid (liquid) to be used is compatible with the meter. Refer to
industry fluid compatibility charts or consult your local representative or distributor for advice.
FLOWMETER USAGE: The flow meter shall be used exclusively with liquids. No gases permitted to flow.
Presence of gases could create severe hazard and damage
STRAINER: To prevent damage from dirt or foreign matter, it is recommended that a Y type or Basket type mesh
strainer be installed 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” 420 micron / 40 mesh
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.
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 to an external receiving element (e.g. Data Logger or PLC) or
alternatively to an LC Display which conditions the Pulse signal to display volume of fluid passed. (e.g. Display 1
Litre per for every 36 pulses received)
Page 3 of 31
INSTALLATION PROCEDURE
1. It is recommended that a bypass line be included
in the design. This provides the facility for a
meter to be removed for maintenance without
interrupting production. (see figure)
2. Use a thread sealant on all pipe threads. Thread
tape must not enter flow meter as this could stop
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. (Page 7)
4. Install a Y type or basket type mesh strainer 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” 420 micron / 40 mesh
The flow meter can accept flow in any direction.
5. The meter can be installed in any orientation as
long as the meter shafts are in a horizontal
plane as per the picture.
Incorrect installation can cause premature wear of
meter components.
Do not over tighten meter connections.
7. It is important after initial installation to fill the line
slowly, high speed air purge could cause damage
to the rotors.
8. Test the system for leaks. Do not continue use if
meter is leaking.
9. 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
Inspection and maintenance should only be carried out by experienced personnel.
DIS-ASSEMBLY
When maintenance to any part of the flow meter is required, it must be isolated and line pressure released. It
must be removed from the line if required. Use non sparking tools to accomplish the job.
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, Page 6)
2. Remove the O-Ring from the O-Ring groove. Clean it nicely and store in clean place.
3. Remove rotors from the cap and shaft assembly. The shafts are fixed to the cap for sizes 1/4” - 2” and to the
body for 3” and 4” sizes. No need to take them off.
Do not remove shafts from their location.
Page 4 of 31
RE-ASSEMBLY
1. Before reassembling, check the condition of flow meter parts (rotors, body, cap, seal O -ring and shafts). Re
place if necessary. Contact Macnaught to check for spare parts availability.
2. One of the rotors is active (have magnets) and other one is neutral. The active rotor can be identified by
running a metal object over the face of the rotor. Placed both the rotors at 90° to each other onto the shafts.
Spin them to check if they move freely. If not, repeat the process.
Active Rotor Placement into Flow meter:
MX06 - MX09 Meters:
The active rotor is positioned nearest to „dimple‟ on the meter cap (see FIG 2, Page 6)
The smooth side of rotor showing up, grub screw will face downwards.
The chamfered side of the rotor stays upward when placed on to the shaft (see FIG 6, Page 6)
MX12 - MX50 Meters:
The active rotor is positioned nearest to „dimple‟ on the meter cap (see FIG 2, Page 6)
Meter cap dimple must face towards the flow meter body dimple (see FIG 2 & 3, Page 6)
The magnet side face upward when placed on the cap
For MX75 - MX100 meters:
Active rotor is positioned on to the shaft away from the flow meter foot. (see FIG 7, Page 6)
The magnet side of the active rotor face upward when placed inside the flow meter body.
3. Smear the O-ring with light film of grease and placed into the Groove (see FIG 3, Page 6)
4. Place the meter Cap on the meter Body.
Meter cap dimple must face towards the flow meter body dimple (MX06-MX50 Meters) (see FIG 2 & 3, Page 6)
5. Insert the cap head screws and tighten in a diagonal sequence 1, 5, 7, 3, etc.
Bolts Torque Ratings:
MX06-MX12 (6.5 Nm)
MX19-MX25 (15 Nm)
MX40-MX100 (33 Nm)
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.

TESTING REED / HALL SWITCHES
Testing of Reed Switch requires
Neodymium magnet (at least 220
Gauss) and Macnaught display/PLC/
FMS/Ohmmeter/Multimeter. If changes
in reading are seen by waiving magnet
near the reed switch, means it is
working fine. Otherwise, the reed switch
is faulty.
Testing Hall Effect Switch requires
Neodymium magnet (at least 220
Gauss), Power Supply/Battery (4.5 - 24
V DC) and Multimeter/Voltmeter.
Correct wiring is shown in the picture.
Check if only one of the magnet poles
changes the signal reading on the voltmeter. It is a clear indication that the
switch is working perfectively. If hall
switch signal is not changing then Hall
switch is faulty.
