INSTALL SILOWEIGH, SILOWEIGH.NET 

SiloWeigh and SiloWeigh.Net vessel weighing systems are self-install kits.  You can do it yourself with a little practice, and we provide the tools for practice before you start, so that you won't mess up the real job.  Read on and see how simple it really is, or ask us for our installation training presentation.

We photographed the SiloWeigh installation at Sinelli Concrete's ready-mix plant, in suburban Detroit.  Lynn Carnacchi is shown installing the system on one of their two vessels.  Other installations are marked as such.

Choose the location

The location which gives best weighing accuracy is in the middle of the longest unobstructed run of the vessel leg, but it should also be in a place where it is easy to work.  Our manual gives you some tips but you make the choice.  In this Dubai installation, we chose to install in the centre of the leg, as indicated by the person pointing.

SILEX BOLTABLE GAUGES - mark and drill holes

Mark a center line and, using drilling template for Silex sensor and center punch supplied, mark and drill attachment holes.  Using junction box as template, mark and drill holes  for mounting screws.  Using smallest drill supplied, drill starter hole and follow with increasing sizes of drill up to full size.  Check sensor against holes for a perfect fit. 

Attach sensor and connect cables

Bolt sensors and connection boxes in place.  Connect the gauge wires to the screw connector block and then connect each leg to the next in daisy-chain fashion, using the cable provided, passing them through the seals in the waterproof covers first.  At each connector block, match all identical colors together for foolproof connection.  The final connection is to the cable which goes to the indicator, mounted in a convenient indoor location.  That's all there is to it!  skip Weldable Gauges below and go to Test and Calibrate, lower down on this page

WELDABLE GAUGES - Prepare the surface

Grind the surface down to bare metal over a 4" square area on both the front and back of the vessel leg, then smooth it with a sanding disk until flat and perfectly smooth.  This is the surface on which the gauges will be welded.  Next drill three holes using the template supplied.  After deburring the holes, clean the area with paint thinner and you are ready to start welding.

Weld the gauges

Try out the welder by welding the practice piece included with the kit onto a piece of scrap steel.  You'll find that it seems tricky at first but practice makes perfect.  Tape the gauge onto the prepared surface using the template supplied, then carefully weld around each of the two gauges in the order detailed in the manual.  Along with the welder, we supply the magnifying visor shown in the picture to make the job easier.

Test the gauges

Once the gauges have been welded in place, feed the wires from the rear gauge through the hole provided and secure all wires with the sticky pad and Tyrap provided.  Test the gauges for continuity and isolation from the beam using the digital meter supplied.  When you are satisfied, coat the gauges with the protective coating supplied in the "nail varnish" bottle.  We supply spare gauges in every kit in case you should damage one.

Make the connections

Connect the gauge wires to the screw connector block and then connect each leg to the next in daisy-chain fashion, using the cable provided, passing them through the seals in the waterproof covers first.  At each connector block, match all identical colors together for foolproof connection.  The final connection is to the cable which goes to the indicator, mounted in a convenient indoor location.

Weatherproof the installation

Apply a thin layer of the silicone RTV sealant over each of the gauges to prevent rust or corrosion.  This is the primary protection for the gauges and will weatherproof the installation without anything further.  To be doubly certain, however, we include protective covers (seen at bottom of picture) which seal out water as well as giving mechanical protection. 

The finished gauge, with its two protective coatings, looks like this.  Note that this is a "round leg" installation, where the covers are installed with bolts vertically aligned, rather than horizontal (courtesy Taeshin, Korea).

Round legs are handled differently

"H" section legs have the gauges installed on the back and front of the leg, with the wires running from the back to the front through a hole.  This is impossible with "O" section legs, so the gauges and covers are installed on opposite sides of the leg and wired together externally.  In all types of leg, the gauges of  each leg are connected to the next in "daisy-chain" fashion.

Seal and fasten cover

Run the two long bolts through the rear cover fastening lugs and thread them through the holes in the beam, pulling the rear cover into position over the gauge assembly.  Thread the front cover onto the bolts, ensuring that the wires and connector block stay inside this cover as it is seated down onto the beam surface.  Assemble washers and nuts but before tightening, apply sealant round the edges of the front and rear covers.  Push into the gap and tighten the bolts just enough to snug the lockwashers down (shown is Sam Park of Taeshin, Korea).

Test and calibrate

Apply power.  Enter your vessel data (capacity, graduation size etc.) into the indicator's calibration memory and wait until the vessel is empty (or as low a level as possible).  Enter your estimate for the remaining weight.  Unload your delivery truck into the vessel and enter the delivery ticket weight as the calibration value.  That's it.  You are ready to go!

Use it every day

Congratulations.  You now have a vessel weighing system.  Use it every day to check your inventory.  Never run out of material again.  The people at Sinelli started using it right after their first delivery and have loved it ever since.  SiloWeigh can do a job for you too.

SiloWeigh.Net and SiloWeigh use the same gauges and installation technique.  When it comes to connecting to the SiloWeigh.Net database, we take over and set it up over the Internet, from our service center. 

You can install SiloWeigh or SiloWeigh.Net just as easily.  Contact us now.
