NEW - ADD TANK LIQUID LEVELS TO YOUR DISPLAY

SiloWeigh.Net internet silo and vessel inventory systemNever 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:

Silex BOLT-ON strain gauge 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. Liquid level sensor for Siloweigh 2 - Liquid level sensor allows monitoring of a mix of solids by weight and liquids by level. 3 - “Traditional” weldable sensor for special applications.

Two types of display:

SiloWeigh BAR GRAPH- the display cabinet can house up to eight bar-graph indicators to display up to eight vessels at the same time.Silo weighing system measures true weight of silo.
  • 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 internet silo and vessel inventory systemSiloWeigh.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.  View a demo by clicking  www.siloweigh.net.
  • 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. 

SiloWeigh.Net database server

View SiloWeigh.Net slide show

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. SiloWeigh.Net server is your source for silo data

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.

Each plant/site holds data for all its vessels

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.

 

Order from the cement supplier

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

HIGH ACCURACY USING LOAD CELLSHIGH ACCURACY USING LOAD CELLSIf 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.
