HAVERNET WEIGHERS
THE HAVER® GROUP
HAVER TYPE 7480 H – HIGH PERFORMANCE NET WEIGHER
The HAVER net weigher’s low mainte-
nance needs, rugged construction
and compact size make it especially
easy to install in existing filling plants.
For providing operational safety, the
double-bottom weigher trapdoors
are equipped with a self restraining
system and remain closed in the
event of a compressed air outage.
All corners are rounded as well.
The filled volume of the container is
up to 120 dm3 and allows a weighing
range of 10 to 50 kg. Mobile filling
plants require operator-friendly
cleaning, and so all containers are
now equipped with cleaning covers
and protective enclosures designed
as doors.
The HAVER MEC® III electronic
weighing system with three load cells
make up an automatic weighing unit
that’s easy to calibrate.
As a result from continuous inno-
vation of our high performance net
weighers, now up to 2,400 dischar-
ges per hour with a consistently
high level of weight accuracy can be
achieved when filling free-flowing
granular material.
COMPONENTS
Dosing unit maintenance cover All parts are easily accessible for mainten-ance and cleaning. The dosing hopper isequipped with a maintenance cover, whichmakes it especially easy and quick to cleanwhen changing over to different products.
Weighing containerEquipped with a double-bottom trapdoorfor providing extremely short dischargetimes. Depending on the product and fill weight, the volume is between 68 -118 litres. Dosing unit maintenance cover
Load cells The weighing container hangs from threeload cell members. This prevents the adverse effects of temperature fluctuationsand assures consistent weight accuracy.
Door enclosuresAll components in the weigher area are easily accessible thanks to an easy-to-remove and lockable metal panel. This panel may be equipped with an electricalmonitoring system if requested.

WEIGHER ELECTRONICS AND DATA PROCESSING SYSTEM
DPS data processing system
The DPS V 4.1 data processing
system is a program for detecting,
recording and reporting process
data. Data from the HAVER weigher
controller and other compatible
check weighers can be collected.
Up to eight packing lines may be
managed simultaneously using the
appropriate PC interfaces. The
weigher data can be evaluated to
produce statistics such as mean
weight, standard deviation, total
weight, total number of bags, etc.
This allows daily, weekly, monthly
and annual reports to be generated,
as well as single weight reports,
weigher diagrams and Gaussian
distribution curves.
The MEC® III weigher electronics
The MEC® III is the result of continu-
ous innovation of HAVER electronic
weighing systems. More than 18,000
electronic weighing units are in
operation worldwide. The MEC® III
can be calibrated and is a PTB
approved measuring instrument with
a resolution of 6,000 increments. In
addition to weighing, the MEC® III
controls the machine functions. The
operation and display of all functions
take place at an operator terminal
with graphic display (see page 4) or
via the MEC® III terminal panel of the
FFS operating system. The simple
and well structured operating
sequences are menu-guided, or
executed simply by pressing a
pictogram function key. Plain text
messages are given in English,
German and in the local national
language.

FUNCTIONAL PRINCIPLE OF THE WEIGHER
The control loop of the HAVER electronic weighing
system delivers the highest level of weight accuracy,
even at maximum filling rates. The weigher adjusts
itself automatically to various products and ambient
conditions.
HAVER NET WEIGHER WITH WATER RINSING
The HAVER net weigher equipped
with automatic water rinsing is an
important success factor in batch
filling operations.
A concept that will convince you
High pressure spray nozzles clean
the entire product area, thus allowing
the weigher and filling system to go
back into operation after the shortest
interruption time. This assures
reliable cleaning whenever changing
the product or colour. And to reduce
the drying time, the area can be
dried with either warm or cold air.
