Low cost, accurate, integrated
indoor control and ..... you can install it yourself!
Never
run out of cement again. Eliminate the risk of overfilling storage
vessels.
SiloWeigh
tells you the contents of any tank or vessel - not as an empty or
full signal, or even a percentage full signal based on a level
measurement. SiloWeigh
measures the actual weight of the vessel and contents to give a
true picture of the amount on hand - and it costs little more than a
level sensor.
All three sensors use high quality foil strain gauges, as used in
high-accuracy load cells, to give superior stability and accuracy.
SiloWeigh
is temperature compensated by matching the sensors to the metal
of the legs. We have demonstrated typical accuracies of
±1 to 2% of full scale when all
four legs are gauged. It is possible to gauge only half the legs
but we do not recommend it since wide variations in accuracy are
possible. You can also mount the legs on Load Cells for high
accuracy (0.1%) (see bottom of page).
All-weather.
Sensors, wiring and junction boxes are
carefully weatherproofed and you can set up the dust and spashproof display system in a
convenient indoor location.
NEW
- THREE types of sensor:
1 - Silex BOLT-ON strain gauge sensors
(shown at left), which attach directly to the vessel's legs,
eliminating the need to lift it onto load cells and making
it easy to install.
2 -
Liquid level sensor
allows monitoring of a mix of solids by weight and liquids by level.
3 -
“Traditional”
weldable sensor for special applications.
SiloWeigh
BAR GRAPH- the display cabinet can house up to eight
bar-graph indicators to display up to eight vessels at the
same time.
Up to eight
Bar-graph indicators in wall-mount cabinet for local
viewing, shows both level and actual vessel weight in
tons, lb, kg etc.
Optional 4
programmable relay alarm setpoints per vessel, based on
weight values, to power alarm lights or bells. These
also have LED indicators on each bar graph.
Optional
analog output for each vessel connects to PLCs and
computer control systems.
Cabinet and
indicators are dust and splash proof. Add display
covers to make them NEMA-4 waterproof. Outdoor use
requires a weatherproof enclosure, cabinet heater or
both.
Install and
calibrate the system yourself. We deliver a kit with
complete instructions. All required cables are provided
and are colour coded. Calibration is straightforward,
using the weighed deliveries as reference.
Alternatively, we have trained installation experts at
various US and Canadian locations - call us for details
SiloWeigh.Net, the
network version, with computer display. The
SiloWeigh.Net
processor is a web server, allowing Internet pages to be generated and viewed
(through an Internet browser such as Internet Explorer) on computers throughout
the local network. You see all your vessels shown as level gauges, plus
the actual weight in tons - and you get a trend graph too. In addition, four types
of alarm are displayed to warn of impending problems - see the yellow 'Reorder'
alarm and red 'Almost Empty' alarm. Setup and calibration is done through
similar screens, password protected for security.
Up to 32
vessels, each with 4 legs, per system (128 sensors total),
using weatherproof digital transmitters at each vessel.
Local data storage for up
to one month ensures no data lost if communication is down.
Vessel
symbols change color as warning, giving high visibility
warning of impending problems.
Optional 24
programmable relay alarm setpoints can be programmed to
light visible indicators, audible alarms or pinch-off valves
to prevent overfill.
Up to 8
inputs can accept alarm cancel button or overpressure
switches to prevent filter blowout.
In addition to the
local display, the SiloWeigh.Net
data can be stored on the
SiloWeigh.Net
database, allowing your company to centralize data for all vessels and all plants.

Yes, we do divided silos.
Most companies cannot handle vessels that are divided to
store two separate materials. Regardless of the position of
the partition, SiloWeigh.Net uses all four legs signals to
compute the weight in each side. It's just as easy to
install, just as easy to calibrate.
Optional Internet
connection to company database or ERP system to order
supplies or dispatch trucks automatically.
We are available to provide
complete technical support, both during and after
installation.
Scale-Tron’s web based database – The
SiloWeigh.Net database is housed on a commercial server with professional
maintenance and backup service to ensure your data is never lost, is secure
from hacker attack and is available to you all the time, any time, 24 hours
a day, 7 days per week. Whether you choose to link the SiloWeigh.Net
database to your own company database or use SiloWeigh.Net’s services for
all your needs, the SiloWeigh.Net server is your source for silo data.
The single database is subdivided among all SiloWeigh.Net’s clients, each
having its own passwords for access.
In your
company’s area, you have the ability to store data for your own customer
companies, divisions and plants or sites. Each plant/site holds
data for all its vessels, which can be displayed individually or as
groups holding the same product. The data can be displayed
directly as tables of data as it is received, or sorted by company,
site, time and date etc. It can also be displayed in graphical
form for each site, as a trend graph which can be zoomed to any time and
date period.
In addition
to the weight data, the database holds a log of each alarm condition
encountered, with time and date.
Any or all
the data is accessible by a remote database server, using TCP/IP
protocol, enabling it to be combined with private company data on
customers, products and orders. This allows clients to organize
dispatching of deliveries or sales.
Individual
client areas can be customized with additional data and reports etc.
Contact us for more details.
Graph at right is actual data from our test site - a working concrete
plant in Canada.
Here's an example of the automatic ordering
process, taken live from the cement company's web site. The
level at the customer's vessel has reached the reorder value and triggered
this order from the cement supplier. Once set up and verified, the
process can proceed without any further manual intervention.
Emergency low
or high levels can also be made to send Emails or SMS messages to cell
phones.
We have installed the SiloWeigh system in our concrete batching plants
in Korea. We have found them easy to install and more accurate
than other similar products when in use. We particularly like easy
calibration and simplicity of installation.
A major benefit of SiloWeigh system that we
have noticed is its ability to calibrate from deliveries of material,
without the need for fully emptying the silo, as is required with
regular weigh scales.
Congratulations on a well made product with
a great future.
Sincerely yours,
TAESHIN CORPORATION
HIGH ACCURACY USING LOAD CELLS
If
you can lift the vessel, the legs can be mounted on load cells. The
feed silos at left were converted without lifting by cutting the bottom of
each leg in turn, refitting the foot and bolting onto the load cell mount.
This gives full load cell accuracy; typically 0.1% of full scale.
Useful when fine accuracy is required or when dealing with awkward leg
styles that either do not allow gauges to be fitted or are too flexible for
accuracy.
