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.

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.
Mark a center line and, using drilling template for L-Strain sensor and center punch supplied, mark and drill attachment holes. 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. The drills supplied are adequate for installation on a few silos. If installation is to be done on many silos, we recommend the use of a drilling machine with magnetic base fitted with a cutter that drills the correct sized hole in a single pass. The best cutters have a hollow center through which a spring loaded pilot pin extends; this locates the cutter onto the center-punch mark.
Bolt sensors and connection boxes in place. Connect the sensor wires to the screw connector blocks and then connect each leg to the Digital Junction Box, 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 a single cable from all the silo DJBs, in daisy-chain fashion, to the indicator or DAQ box (SiloWeigh.Net), mounted in a convenient indoor location. Conduit is not supplied but you can use it if you choose. Always enter the J-boxes from below to eliminate leakage problems.
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 good to go!
