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.
NEW
- THREE
types of sensor:
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.
“Traditional”
weldable
sensor for special applications.
Liquid level sensor
allows monitoring of a mix of solids by weight and liquids by level.
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. All components are
carefully weatherproofed and you can set up the display system in a
convenient indoor location.
Digital bar-graph indicator for each vessel
shows both weight of contents and level in vessel, calibrated in English
or metric tons for solids, or liters, gallons etc. for liquids.
SiloWeigh
BAR GRAPH- the display cabinet can house up to five bar-graph indicators to
display up to five vessels at the same time - see picture above right.
SiloWeigh.Net, the
NEW
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 - see picture at right. 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.
Optional digital outputs on both models can be wired to alarm lights and
bells, while SiloWeigh.Net can also accept inputs from overpressure sensors to
warn of impending dust collector problems.
In addition to the vessel display, the SiloWeigh.Net
data can be used with a local database or stored on the
SiloWeigh.Net
database, allowing your company to centralize data for all vessels and all plants.

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.
Yes, we do divided silos. Most companies
cannot handle vessles 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.
We are available to provide complete technical
support, both during and after installation.

.
SiloWeigh and
SiloWeigh.Net
can display the weight of contents in practically
any vessel. Examples are: cement, sand, aggregates, flour,
grains such as corn, rice, wheat, oats, barley, mineral ores, coal, coke,
chemicals, plastics, liquids such as concrete admixtures, food materials and liquefied gases. The easiest application
is on H-beam
legs, but "O" (round) section, square, "L" and "S" sections have been gauged
successfully, as well as skirted silos. The only limitation is the
available stress in the leg. The stress can be calculated by measuring
the cross sectional area of the leg and dividing the maximum "live load" in
the leg by the area. The calculated stress should be at least 1500
lb/sq.inch (105 kg/sq.cm) for best results.
Example: a vessel holds 100 tons (200,000 lb) of cement and has 4 legs,
each with a cross section of 12 square inches. Each leg will carry a
maximum live load of 200,000/4 = 50,000 lb. Dividing this by 12 gives
4166 lb/sq.in, which is safely above the limit of 1500. Note that legs
that are designed for greater safety margins will have less stress and will
have a lower electrical output as a result. The lower output will
increase the drift in readings due to temperature changes and side loads.
SILOWEIGH.NET IS VIEWED ON LOCAL AREA NETWORK AND BY REMOTE INTERNET CONNECTION
The power of the SiloWeigh.Net system is the ongoing connection
to the local database or the SiloWeigh.Net database server. The client’s company database is
accessible by any web browser (via passwords to ensure total security), enabling
the client (cement, concrete or similar company) to see all customers’ vessel
levels and dispatch deliveries accordingly. End users can see their own
vessels’ status and order directly on-line.
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 record 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.
