A better way to manage your bulk material inventory

Never run out of cement again.  Eliminate the risk of overfilling storage vessels.  SiloWeigh.Net tells you the contents of any silo, tank or vessel - not as an empty or full signal, or even a percentage full signal based on a level measurement. Better than silo level measurement, SiloWeigh.Net measures the actual weight of the storage vessel and contents to give a true picture of the amount on hand - and it costs little more than a silo level sensor.  SiloWeigh.Net is an inventory system, with a database containing the weight history of all your vessels, allowing qualified personnel to acess your inventory anywhere; local vessel displays on any computer in the local network plus an Internet site with all the company's vessel data available at one source.  Click HERE for live demo in a real plant.  Username: demo, Password: demo. Click on any silo to see the trend graph; more links below graph.
Been running V2 on 8 silos for over a year now. Unbelievable how accurate the system is. Using both Silex sensors and weldable gages on older silos and has been trouble free. Only needed to contact us when system had to be moved onto main server and service was excellent.   Matt, Chicopee Concrete Services Inc., October 2014 configuration uses single multi-drop cableConnections

CABLE or RADIO transmission reduces wiring between silos and DAQ unit to a single digital cable, reducing installation time and preserving full accuracy - up to 10 miles (16 km) from silos. Digital Junction Boxes connect to all sensors at each vessel.  The DAQ unit gathers digital data from all vessels, storing it for transmission to a local computer and assuring no-break operation.  The associated computer acts as a web server, allowing any computer on the local area network to view the levels in all vessels or a detailed view of one vessel with a trend graph, using just a web browser.  See GUI page for details.  Note that several locations can be networked by radio to enhance coverage - see Applications for details.
NEW built-in "brick" PC computer eliminates setup at site - whole system is "Plug-and-Play".

 SiloWeigh.Net alarm system is programmable


8 to 24 optional relay alarm setpoints can be programmed to light visible indicators, sound audible alarms or operate pinch-off valves to prevent overfill.  Aditionally, up to 8 inputs can accept alarm cancel buttons or overpressure switches to prevent filter blowout.

Relays are popular `Opto-22`type, available everywhere.

Divided silos

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.
