TICKET PRINTER
9.1
A ticket printer may be fitted above the mechanical counter to provide a printed record of each
product delivery through the bulkmeter.
9.2
Two basic types of printer are available, Accumulative and Zero start.
9.3
The accumulative printer records the total amount metered before and after each delivery. The Zero
start printer records only the total for each seperate delivery.
10
MECHANICAL PRESET REGISTER AND VALVE
10.1
Presets the quantity to be delivered and shuts off flow, without shock, when the set delivery has
passed through the meter. Available in 2.5”, 3” and 4” sizes.
11
RATE OF FLOW INDICATOR
11.1
Where indication of flow rate is required so that a definite maximum or minimum flow rate may be
maintained.
11.2
The Indicator consists of a calibrated and compensated tachometer incorporated in the front cover of
the calibrating unit and driven by a gear train. The Rate of Flow Indicator may be calibrated in
Imperial Gallons and Litres, or US Gallons.
12
TEMPERATURE COMPENSATOR
12.1
Designed to operate over a wide temperature range, the Temperature Compensator automatically
adjusts the indicated volume on the counter to an equivalent volume at the standard temperature (60
°
F or 15
°
C). Dual readout can be provided - one counter showing corrected volume and a second
counter showing actual volume.
13
ADDITIVE MECHANISM
13.1
13.2
Provides
automatic
in-line
blending
of
bulkmetered
fuel
with
one
or
two
additive
mixtures
at
pre-determined
ratios.
The
Additive
Mechanism
is
mounted
on
the
rear
of
the
bulkmeter
which
requires
a
different
outer
rear
cover
fitted
to
allow
drive
to
be
taken
off
the
rear
stub
axle
of
the
rotor.
Ideally,
the
Additive
Mechanism
should
either
be
ordered
with
the
bulkmeter
or
the
bulkmeter
ordered
with
the
provision
for
an
Additive
Mechanism
to
be
installed
at
a
later
date.
In
which
case
the
bulkmeter
will
be
delivered
with
a
special
rear
outer
cover
factory
fitted.
The
rear
drive
shaft
will
be
covered
by
a
removable
guard.
In
cases
of
retro-fitting
to
an
existing
bulkmeter,
a
new
rear
outer
cover
will
be
required
and
this
must
only
be
fitted
by
a
qualified
engineer
with
full
workshop
facilities.
If
this
is
not
possible,
return
the
bulkmeter
to
Liquid Controls
for
modification.
