Selecting the right metering equipment is one of the most important decisions in packaging automation. Whether you're filling granular snacks, fine powders, or irregular-shaped products, the choice between cup fillers, auger fillers, and multihead weighers directly impacts your production efficiency, accuracy, waste reduction, and ROI.
In this comprehensive guide, we'll compare these three dominant metering equipment technologies to help you make an informed decision based on your product characteristics, accuracy requirements, speed needs, and budget constraints.
Volumetric cup fillers measure products by volume using precision cups of predetermined sizes. Material flows from a hopper into measuring cups, which then discharge a fixed volume into the packaging.
How They Work:
Best For: Free-flowing granular materials with consistent density—cereals, grains, seeds, pet food, nuts, coffee beans, and similar products.
Auger fillers use a rotating screw (auger) to meter product by volume. The number of auger rotations determines the amount dispensed, making them ideal for fine, non-free-flowing materials.
How They Work:
Best For: Fine powders, flour, spices, protein powders, pharmaceutical powders, cosmetic powders, and other non-free-flowing materials.
Multihead weighers (also called combination scales) use multiple weighing buckets and advanced algorithms to achieve precise weight-based filling. They're the gold standard for accuracy and speed in high-volume operations.
How They Work:
Best For: Wide range of products—snacks, frozen foods, fresh produce, confectionery, nuts, dried fruits, irregular shapes, and applications requiring high accuracy (±0.5-2g).
Explore our range of precision multihead combination weighers for demanding applications.
Multihead Weighers: ⭐⭐⭐⭐⭐ (Highest accuracy, ±0.5-2g typical)
Weight-based measurement eliminates density variation issues. Ideal for strict weight compliance and giveaway reduction.
Cup Fillers: ⭐⭐⭐ (Good for consistent products, ±2-5g typical)
Accuracy depends on product density consistency. Excellent for free-flowing materials with stable bulk density.
Auger Fillers: ⭐⭐⭐⭐ (Very good for powders, ±1-3g typical)
Reliable for fine powders when properly calibrated. Performance affected by powder flowability and aeration.
Multihead Weighers: ⭐⭐⭐⭐⭐ (60-120+ bags/min)
Fastest option for high-volume production. Parallel weighing enables exceptional speeds.
Cup Fillers: ⭐⭐⭐⭐ (40-80 bags/min)
Fast and efficient for straightforward applications. Simple mechanics enable reliable high-speed operation.
Auger Fillers: ⭐⭐⭐ (20-60 bags/min)
Slower due to sequential auger rotation cycles. Speed limited by powder flow characteristics.
Multihead Weighers: ⭐⭐⭐⭐⭐ (Handles almost anything)
Exceptional versatility—granules, powders, sticky products, fragile items, irregular shapes. Quick changeovers between products.
Cup Fillers: ⭐⭐⭐ (Best for free-flowing granules)
Limited to products that flow consistently into cups. Struggles with sticky, clumping, or irregular materials.
Auger Fillers: ⭐⭐⭐⭐ (Excellent for powders)
Specialized for fine powders and non-free-flowing materials. Less suitable for large granules or chunky products.
Cup Fillers: ⭐⭐⭐⭐⭐ (Lowest cost, $3,000-$15,000)
Most economical entry point. Simple mechanics reduce upfront investment.
Auger Fillers: ⭐⭐⭐⭐ (Moderate cost, $8,000-$25,000)
Mid-range pricing. Cost varies with precision requirements and automation level.
Multihead Weighers: ⭐⭐⭐ (Higher cost, $20,000-$80,000+)
Premium investment justified by accuracy, speed, and versatility. ROI typically achieved in 12-24 months through waste reduction and throughput gains.
Cup Fillers: ⭐⭐⭐⭐⭐ (Minimal maintenance)
Simple design, few moving parts. Easy cleaning and cup replacement.
Auger Fillers: ⭐⭐⭐ (Moderate maintenance)
Auger wear requires periodic replacement. Cleaning can be time-intensive for sticky powders.
Multihead Weighers: ⭐⭐⭐⭐ (Moderate maintenance)
Load cells require calibration. More components but modern designs minimize downtime.

Recommended: Cup Fillers or Multihead Weighers
Cup fillers excel with consistent flakes and granola. Multihead weighers handle mixed cereals with varying piece sizes and deliver superior accuracy for premium products.
Recommended: Multihead Weighers
Irregular shapes, fragile products, and strict weight requirements make multihead weighers the industry standard for snack packaging.
Recommended: Auger Fillers
Fine powders with strict dosing requirements benefit from auger precision. GMP-compliant designs ensure contamination-free operation.
Recommended: Cup Fillers or Multihead Weighers
Standard kibble works well with cup fillers. Premium treats with mixed sizes or soft/chewy textures require multihead weighers.
Recommended: Cup Fillers (whole bean) or Auger Fillers (ground coffee)
Whole beans flow consistently into cups. Ground coffee's variable density and static make auger fillers more reliable.
When evaluating metering equipment, consider these ROI factors:
Multihead weighers typically reduce giveaway by 30-50% compared to cup fillers. For a product worth $10/kg running at 60 bags/min with 3g average giveaway reduction:
Automated metering eliminates manual scooping, reducing labor costs and improving consistency. One operator can manage multiple automated lines.
Upgrading from 40 bags/min (cup filler) to 80 bags/min (multihead weigher) doubles capacity without doubling floor space or labor.
Weight-based systems reduce customer complaints, regulatory risks, and product recalls—costs that are difficult to quantify but critically important.
Your metering equipment doesn't operate in isolation. Consider integration with:
Explore our complete metering and pump equipment solutions for integrated packaging lines.
The cheapest option often costs more long-term through waste, downtime, and lost capacity. Calculate total cost of ownership over 5-10 years.
Test your actual product before purchasing. Density variations, moisture content, and particle size distribution dramatically affect performance.
Select equipment with headroom for increased speeds and product variety. Upgrading later is more expensive than buying right the first time.
Factor in cleaning time, spare parts availability, and technical support when comparing options.
Ensure equipment meets industry standards (FDA, GMP, HACCP) for your sector—especially critical in food and pharmaceutical applications.
Choosing between cup fillers, auger fillers, and multihead weighers depends on your unique combination of product characteristics, accuracy requirements, speed needs, and budget constraints:
The right choice balances upfront investment against long-term operational efficiency, waste reduction, and scalability. For many operations, the superior accuracy and throughput of multihead weighers justify the premium investment through measurable ROI within 12-24 months.
