Filling Technology: Net Weight vs. Flow Meter Systems
As liquid filling applications become more diverse and demanding, selecting the right equipment is critical to ensuring accuracy, efficiency, and long-term cost savings. Two standout filling technology solutions from the Massman Companies portfolio—Ideal Pase Automatic Inline Net Weight Fillers and DTM Packaging Flow Meter-Based Walking Beam and Indexing Machines — offer distinct advantages depending on your product and production needs.
Let’s explore how these two systems compare, and where each performs best.
Ideal Pase Inline Net Weight Filling Machines
Ideal Pase Net Weight Fillers use precision load cells to dispense product based on actual weight. This makes them the go-to choice for products sold by weight or those that present challenges for volumetric filling.
Key Benefits:
- High Accuracy: Delivers precision to ±0.1% – 0.5%, ideal for high-value products.
- Non-Contact Filling: Great for corrosive materials like acids and bleaches.
- Versatility: Capable of handling a wide range of viscosities and container sizes, from pints to pails and drums to totes.
- Foam-Friendly: Fill accuracy is unaffected by foam, making it ideal for challenging liquid profiles.
Best Applications:
- Chemical products such as acids and bleaches
- Lubricants, paints, and coatings
- Food-grade oils, flavorings and industrial liquids
- Large fills—pails, drums, totes
- Batch Filling – where fast product changeovers are a necessity
- Environments where sanitation and CIP/SIP compatibility are key
DTM Packaging Flow Meter-Based Walking Beam & Indexing Machines
DTM’s Flow Meter Fillers utilize either magnetic or mass flow meters to measure product volume or mass in motion. These systems excel in high-speed applications where throughput and quick changeovers are essential.
Key Benefits:
- High-Speed Filling: Walking beam and indexing mechanisms ensure precision positioning and rapid cycle times.
- ±0.25% Fill Accuracy: Especially effective for water-like or low-viscosity fluids.
- Built–In pressurized tank – Allows the Purefil to fill more viscous products
- Fast Changeovers: Recipe-driven electronic changeovers reduce downtime between SKUs.
- Integrated CIP System also supports fast product changeovers.
- Compact Footprint: Ideal for integrated packaging lines.
Best Applications:
- Personal care products like shampoos, lotions, and hand sanitizers
- Household chemicals such as cleaners and detergents
- Beverage and food products include juices, sauces, and vinegars
- Pharmaceutical or nutraceutical liquids where hygienic design is essential
Side-by-Side Comparison
| Feature | Ideal Pase Net Weight | DTM Flow Meter |

| Best For | Bulk, foamy, corrosive, costly products | Bottles to Gallons – high-speed retail fills |
Which One Is Right for You?
If your operation deals with challenging liquids, high-value materials, or requires precise weight control, the Ideal Pase Net Weight system is a smart investment. On the other hand, if you’re running high-speed bottling lines for consumer-grade liquids, chemicals and food and need rapid product changeovers, DTM’s Flow Meter fillers provide unbeatable efficiency.
