Sequential Blending
• Blending of More Than One Product Into a Truck Through the Sequencing of Product-Specific Block Valves One Product at a Time Through One Meter With Up to 50 Recipes Available.
• The ratio of varying products is designated in the recipe as a percentage of the total preset.
• These percentages must total 100%.
• AccuLoad automatically calculates the actual volumes of each product to be delivered.
• The order of product delivery must be included in the recipe definition.

Ratio Blending
• Blending More Than One Product Into a Truck Simultaneously Through Dedicated Product Lines Each Having Its Own Meter and Control Valve Co-Mingling in a Common Header
• The ratio of the component products is designated in the recipe as a percentage of the total preset.
• These percentages must total 100%.
• The AccuLoad III automatically calculates the actual volumes of each product to be delivered.
• Flow rates are adjusted for optimal blend accuracy while conforming to the programmed system flow profile using Smith's exclusive control algorithm.

Hybrid Blending
• Hybrid Blending is a Combination of Sequential Blending and Ratio Blending.
• Suited for Applications Such as Ethanol Blending or Bio-Diesel Blending.
• The Sequential Products Flow One at a Time.
• Ratio Products Flow Simultaneously with Each of the Sequential Products.
• Ratio Product(s) can be Plumbed Either Upstream or Downstream of the Sequential Product Meter.
• Up to 5 Ratio Product Meters on One Arm
