IMPORTANT INFORMATION

(READ CAREFULLY)

EQUIPMENT CATEGORY: The Macnaught oval gear flow meters are designed in category II 2 G according to EN 60079-0 and EN 60079-11 for use in zone 1. The inside of the measuring unit is also approved for zone 1. Macnaught declines any responsibility for the use of flow meters outside the designated Ex group, category and zone.
The flow meters shall be rigorously used within the min-max rated temperature and pressure limits specified by Macnaught. Failure to do so will result in high risk of explosion.

EU CONFORMITY: The manufacturer declares with the EU declaration of conformity on his own responsibility conformity with the protection goals of directive 2014/34/EU for use in hazardous areas with gas. The EU declaration of conformity for the equipment category II 2 G is based on the EU type technical file SIRA: SIRA
15XT063 Rev 4.

POTENTIAL RISK OF EXPLOSION: Do not run the flow meter in conditions that would cause overheating, damage and potentially create high risk of explosion in hazardous area. The flow meter must be protected from impact at all times: impact can cause mechanical sparking and result in high risk of ignition/explosion The flow meter external housing can made of Aluminium: contact between iron oxide (for example - rust iron) and aluminium can cause sparks with high risk of ignition/explosion. Ensure no source of iron oxides are available within the Ex zone where the flow meter is installed. In the event a leakage on the flow meter is observed, process must be interrupted immediately and proper maintenance carried out. Leakages could create dry run condition in the meter with resulting risk of ignition/ explosion.
FLOWMETER USAGE: The flow meter Shall be used exclusively with fluids. No gases permitted to flow. Presence of gases could create severe hazard and damage

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.

SAFETY BARRIER: Use appropriate safety barriers for outputs. Refer to below pages for Entity Parameters:
· Page 11 - Reed Switch · Page 12 - ERX Display (Type Fx) · Page 14 - ERAX Display (Type Gx) · Page 16 - ERBX Display (Type Hx)

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.

· 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)
INSTALLATION INSTRUCTIONS
INSTALLATION: Assembly, installation, start-up and maintenance may only be must be carried out according to the applicable installation standards (e.g. IEC 60079-14) by qualified personnel trained in explosion protection! The information given in the manual and these instructions must always be observed: failure to observe the instructions on this manual will result in a high risk of explosion. The operator or his agent is responsible for observing any additional standards, directives or laws if required due to operating conditions or place of installation. This applies in particular to the use of easily detachable process connections when measuring flammable media. When an equipment fault is detected the device shall be de-energised and send back to the manufacturer for repair.
EARTHING/EQUIPOTENTIAL BONDING: The flow meter must be included in the on-site equipotential bonding system according to EN 60079-14. Proper earthing and equipotential bonding provisions shall be in place and properly maintained on the flow meter and the whole installation, as per EN/IEC 60079-14 or any other relevant applicable standards. Failure to do so would result in high risk of static sparking and explosion. See Images on Page (5) for earthing/equipotential bonding points on flow meter.
ELECTROSTATIC CHARGE: In order to avoid ignition hazards due to electrostatic charge, flow meters may not be used in areas with: · processes that generate strong charges, · mechanical friction and cutting processes, · spraying of electrons (e.g. in the vicinity of electrostatic painting systems) or · pneumatically conveyed dust is exposed.
Electrostatic charging of the housing surface by friction must be avoided. The devices must not be dry cleaned. If you feel an electric shock while using the meter, stop dispensing immediately. Identify and correct the problem before continuing.
IMPORTANT NOTES: After installation and before start up, the flow meter must be primed and the air in the pipework purged to avoid onset of dry run conditions in the flow meter: that could cause damage and risk of explosion if persistent.
Do not install the flow meter in close proximity of a source of heat (for ex. furnace, heater) that can cause an increase of flow meter temperature: hot surfaces on the flow meter can cause risk of explosion
Proper strainers/filers shall be used to avoid debris of foreign bodies to reach the oval gears: failure to do so would result in severe damage and mechanical sparking with high risk of ignition/explosion.

INSTALLATION INSTRUCTIONS
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)

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.

2. Use a thread sealant on all pipe threads. Thread tape must not enter flow meter, stopping flow
meters operation.

7. It is important after initial installation to fill the line slowly, high speed air purge could cause damage
to the rotors.

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 Y type or basket type mesh strainer as close as possible to the inlet side of the meter.

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 of installations should only be carried out by experienced personnel.
DISASSEMBLY
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.
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 7)
2. Remove the O-Ring from the O-Ring groove. Wipe clean of grease 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.
REASSEMBLY
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 7)
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 7)

MX12 - MX50 Meters: The active rotor is positioned nearest to `dimple' on the meter cap. (see FIG 2, Page 7) Meter cap dimple must face towards the flow meter body dimple. (see FIG 2 & 3, Page 7) 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 7) 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 7)

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
7)

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.
