Installation
1] GPI recommends that when setting
up pipework 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 Fig.1)
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.
4] Install a wire mesh strainer (Y or
basket type 60 mesh 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 Fig.2 for correct
Operation
When fluid passes through the meter,
the rotors turn. The magnets which are
located in the rotors will pass across
the pulser circuit board (containing
either Reed switches or Hall Effect
installation) The register assembly
may be orientated to suit the
individual installation.
Note: Incorrect installation can cause
premature wear of meter
components.
7] Do not over tighten meter
connections.
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.
sensors). A signal is received which is
then sent by the Pulse Circuit Board
(PCB) to the relevant LC display or
receiving instrument.
