The mortar plant sand product must be sampled regularly but the only place to do so was at the input point to the silo which was 40 metres high. This was deemed unacceptable, so the fitter came up with an idea to make a sample point into the chute at the bottom of the elevator. The system took a sample across the full product flow and reduced the need to climb to the top of the silo and return with a sample load.
