Important Information
Operating Principle
Installation Procedure
WARNING
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.
When a strainer is installed it should be
regularly inspected and cleaned. Failure to
keep the strainer clean will dramatically effect
flow meter performance.
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
CAUTION
CAUTION
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..
1) It is recommended that when setting up pipe work
for meter installations 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 above)
2) Use thread sealant on all pipe threads.
3) For pump applications ensure pipe work has
the appropriate working pressure rating to match
the pressure output of the pump. See Meter
Specifications section for further details.
4) Install a wire mesh strainer, Y or basket type
60 mesh (250 micron), as close as possible to
the inlet side of the meter.
5) Ensure that the meter is installed so that the
flow of the liquid is in the direction of the
arrows embossed on the meter body.
6) The meter can be installed in any
orientation as long as the meter
shafts are in a horizontal plane.
(Refer to figures to the right for
correct installation) The register
assembly may be orientated to suit
the individual.
Note: Incorrect installation can
cause premature wear of meter
components.
7) Do not over tighten meter connections. Note:
Incorrect installation can cause premature wear
of meter components.
8) It is important that after initial installation you
fill the line slowly, high speed air purge could
cause damage to the rotors.
9) Test the system for leaks.
10) Check the strainer for swarf or foreign material,
after the first 200 litres check periodically,
particularly if the flow rate decreases.
