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 60 mesh strainer be
installed as close as possible to the
inlet side of the meter. Contact your
local representative for advice.
Note:
When a strainer is installed it
should be regularly inspected and
cleaned. Failure to keep the strainer
clean will dramatically effect flow
meter performance.
Note:
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.
Maintenance can be carried out to the
liquid crystal displays and pulse units
without removing or isolating the meter
from the line. When maintenance to
any other part of the meter is required,
the meter must be isolated and the line
pressure reduced.
The reed switch pulse unit can cause
inaccurate rate counts when used with
high speed counters. It is advised that a
debounce circuit be used. Contact your
meter distributor for further
information.
When fluid passes through the meter
the rotors turn, as shown below. The
magnets which are located in the rotors
will pass across the pulser circuit board
(containing either Reed switches or
Hall Effect sensors). A signal is
generated which is then sent by the
Pulse Circuit Board (PCB) to the
relevant LC display or receiving
instrument.
Operating Principle
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 GM005
Series meters with Pulse outputs. For
models with an Liquid Crystal Display
an additional instruction manual is
supplied. If you need further assistance,
contact your local representative or
distributor for advice.
This Flow Meter 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
oval rotor flow meters are suitable for
both gravity and pump (in line)
applications.
Flow meters are available in either
Aluminium or 316 Stainless Steel.
Standard rotors are made from PPS
(Polyphenylene Sulfide Resins) with
optional 316 Stainless Steel rotors
available for both Stainless steel and
Aluminium models.
GM005 Series Meters are available
with either;
* Pulse output
* Standard LC Display and Pulse
