M1 SERIES INSTRUCTION MANUAL
TO THE OWNER
Please take a few minutes to read through this
manual before installing and operating your
meter.
Always retain this manual for future referen e.
If you have any problems with the meter, refer
to the maintenan e and trouble shooting
se tions of this manual.
This manual ontains onne tion and operating
instru tions for the meters. If you need further
assistan e, onta t your lo al representative or
distributor for advi e.
This Flowmeter has in orporated the oval rotor
prin ipal into its design.
This has proven to be a reliable and highly a urate
method of measuring flow.
Ex eptional repeatability and high a ura y
over a wide range of fluid vis osities 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) appli ations.
Flowmeters are manufa tured in either PPS
(Polyphenylene Sulfide Resins) , Aluminium & 316
Stainless Steel.
Standard rotors are made from 316 Stainless Steel
with optional PPS rotors with Hastalloy C Shafts
available.
OPERATION
Before use, confir the fluid to be used is co -
patible with the eter. Refer to Industry fluid
co patibility charts or consult your local
representative for advice.
To prevent da age fro dirt or foreign atter it
is reco ended that a Y or basket type 200
esh strainer be installed as close as possible
to the inlet side of the eter. Contact your
local representative for advice.
PLEASE READ THIS INFORMATION
CAREFULLY BEFORE USE!
Note:
To prevent da age to the eter slowly fill the
syste with fluid (this will prevent da age
caused by air purge).
Failure to do this could da age the eter.
To reduce pressure build up turn off the pu p at
the end of each day.

INSTALLATION
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-dire tional.
3.The use of flexible onne tions is re om-
mended.
4. Extreme are must be taken when installing
the meter. Pipe strain or over tightening meter
onne tions an ause meter damage.

MAINTENANCE
Disasse bly
1. Ensure the fluid supply to the meter has been
dis onne ted, and the line pressure has been
released before disassembly.
2. Remove four (4) s rews (Item 3) and remove the
meter ap (Item 2).
3. Remove o-ring (Item 5) and inspe t (repla e o-ring
if damaged).
4. Remove rotors (Item 4), lean and inspe t
(repla e rotors if damaged).
Reasse bly
1. Pla e rotors (Item 4) into the meter body. The
rotors should be at 90 degrees to ea h other.
Note: The rotor with magnets must be pla ed 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. Repla e the meter ap (Item 2).
Note: The groove on the over must line up with
the groove on the meter body (refer to diagram).
5. Repla e four s rews (Item 3).
CAUTION:
Care ust be taken not to over tighten the screws
(Ite 3) or da age ay occur.
