2. WHY DO WE NEED MOISTURE MEASUREMENT? Wet cast – measurement in sand corrects both sand weight and water Wet cast – measurement in sand corrects both sand weight and water Dry cast – measurement in sand corrects sand weight only – additional measurement required in mixer Dry cast – measurement in sand corrects sand weight only – additional measurement required in mixer Benefits in product: Consistent slump Consistent workability Consistent color/ texture Consistent maximum strength Less wasted batches Less testing labor

3. PRINCIPLE OF OPERATION Dual detector measures reflection distance Dual detector measures reflection distance Peak detection ignores voids when averaging Peak detection ignores voids when averaging 3 averaging methods – fast, slow, sampling 3 averaging methods – fast, slow, sampling THE 3 ESSENTIALS FOR ACCURACY: THE 3 ESSENTIALS FOR ACCURACY: Measurement within flow region Measurement within flow region “Sampling” creates average during flow period “Sampling” creates average during flow period Compaction of material gives constant density Compaction of material gives constant density

4. COMPARISON WITH OTHERS Costs 30% less than Hydronix Hydro Probe-II while equal in performance Costs 30% less than Hydronix Hydro Probe-II while equal in performance Linear output – separate box not required Linear output – separate box not required Does not require separate power supply Does not require separate power supply One-hole installation is simpler than any other One-hole installation is simpler than any other Long enough for all hoppers – no adaptor needed Long enough for all hoppers – no adaptor needed Empty bin detection prevents spoiled batches Empty bin detection prevents spoiled batches The only sensor with 5 year wear guarantee The only sensor with 5 year wear guarantee Computer software gives 1-step calibration Computer software gives 1-step calibration Fast service from Canada, instant engineering help Fast service from Canada, instant engineering help Over 1000 installed, long track record Over 1000 installed, long track record
