Macnaught M1 Series User manual

PLEASE READ THIS INFORMATION
CAREFULLY BEFORE USE!
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.
To prevent damage from dirt or foreign
matter it is recommended that a Y or
basket type 200 mesh strainer be
installed as close as possible to the inlet
side of the meter. Contact your local
representative for advice.
Note:
To prevent damage to the meter slowly
fill the system with fluid (this will
prevent damage caused by air purge).
Failure to do this could damage the
meter.
To reduce pressure build up turn off the
pump at the end of each day.

The experts in fluid technology
Please take a few minutes to read
through this manual before installing
and operating your meter. Always
retain this manual for future reference.
If you have any problems with the
meter, refer to the maintenance and
trouble shooting sections of this
manual.
This manual contains connection and
operating instructions for the meters. If
you need further assistance, contact
your local representative or distributor
for advice.
This Flowmeter has incorporated the
oval rotor principal into its design. This
has 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 rotor design. With low pressure
drop and high pressure rating means
oval rotor flow meters are suitable for
both gravity and pump (in-line)
applications.
Flowmeters are available in either PPS
(Polyphenylene Sulfide Resins),
Aluminium or 316 Stainless Steel.
Standard rotors are made from 316
Stainless Steel with optional PPS rotors
with Hastalloy C Shafts available.

1. Use thread sealant on all pipe
threads.
2. Ensure the meter is installed so that
rotor shafts are always in a
horizontal plane. Flow is bi-
directional.
3. Macnaught recommends use of
flexible connections.
4. Extreme care must be taken when
installing the meter. Pipe strain or
overtightening meter connections
can cause meter damage.

Disassembly:
1. Ensure the fluid supply to the meter
has been disconnected, and the
line pressure has been released
before disassembly.
2. Remove four (4) screws (Item 3) and
remove the meter body cover (Item
2).
3. Remove o-ring (Item 5) and inspect
(replace o-ring if damaged).
4. Reomve rotors (Item 4), clean and
inspect (replace rotors if damaged).
Reassembly:
1. Place rotors (Item 4) into the meter
body. The rotors should be at 90o
to each other.
Note: The rotor with magnets must be
placed in the body on the same side as
the groove on the body (refer to
diagram).
2. Lightly rotate the rotors (Item 4) by
hand (they must rotate freely).
3. Install o-ring (Item 5).
4. Replace the meter cap (Item 2).
Note: The groove on the cover must
line up with the groove on the meter
body (refer to diagram).
5. Replace four screws (Item 3).
CAUTION:
Care must be taken not to overtighten
the screws (Item 3) or damage may
occur.
