The following criteria consistently determine long-term performance:<\/p><h3 data-start=\"2477\" data-end=\"2517\">1. Material Type and Particle Size<\/h3><p data-start=\"2518\" data-end=\"2711\">Fine powders, granules, and irregular solids behave very differently. Cohesive materials tend to form bridges and buildup, while free-flowing solids can exert high impact forces during filling.<\/p><h3 data-start=\"2713\" data-end=\"2752\">2. Bulk Density and Flow Behavior<\/h3><p data-start=\"2753\" data-end=\"2911\">Bulk density is rarely constant. Moisture, compaction, and material source can all affect how much force the level switch experiences at the same fill height.<\/p><h3 data-start=\"2913\" data-end=\"2943\">3. Installation Location<\/h3><p data-start=\"2944\" data-end=\"3104\">Top-mounted and side-mounted installations experience different loading patterns. Side-mounted devices must withstand lateral pressure and potential compaction.<\/p><h3 data-start=\"3106\" data-end=\"3151\">4. Maintenance Access and Blockage Risk<\/h3><p data-start=\"3152\" data-end=\"3289\">In many silos, access is limited. Devices that require frequent cleaning or recalibration increase operational risk and maintenance cost.<\/p><p data-start=\"3291\" data-end=\"3433\">These criteria form the foundation for selecting a technology that aligns with <strong data-start=\"3370\" data-end=\"3398\">how the material behaves<\/strong>, not how it is described on paper.<\/p><hr data-start=\"3435\" data-end=\"3438\" \/><h2
