The FWS-300E1 liquid quantitative filling scale is a device used in industries such as chemical, grain, and pesticide production for the automatic weighing and packaging of liquid materials. It employs a highly precise, all-electronic weight detection method to accurately measure and control the automatic quantitative filling of bulk raw materials into drums. With its high degree of automation, this system minimizes material spillage, significantly reducing environmental contamination caused by the materials themselves. As a result, it provides effective labor protection for operators. Moreover, the system can operate reliably in humid, hazardous, or other adverse environments.
This product offers two types of filling process control: liquid-level type and submersible type. For general-purpose materials that do not produce foam, the liquid-level filling method is used; for materials that tend to foam, the submersible filling method is employed. In this method, the feed inlet remains below the liquid surface and rises along with the liquid level, effectively preventing bubble formation, material overflow, and accelerating the filling speed. The spray gun designs are available in two models: FA for high-viscosity materials and FB for low-viscosity materials. Featuring a unique clamp-type connection structure, these spray guns are easy to disassemble and clean, making them suitable for filling materials of various viscosities. The filling scale primarily consists of a spray gun assembly, a system controller, an all-electronic weighing platform, mechanical structural components, and a conveyor roller system. It boasts a compact and rational design, stable and reliable operation, and simple installation and operation procedures. Moreover, it can be readily adjusted to suit different site conditions and production capacities, fully meeting user requirements.
The FWS-300 series multi-barrel automatic filling scale is designed to meet the needs of automated filling for a wide variety of liquids. This scale employs either overfill or underfill techniques, enabling it to precisely dispense multiple liquids into several open-top (or perforated) containers placed on a pallet according to pre-set values. Its uniquely designed spray-gun assembly is easy to operate, ensuring fast and accurate filling while minimizing residual liquid drips at the end of the filling process. During operation, the operator simply manipulates the handle to align the barrel opening directly beneath the spray nozzle, then positions and locks it securely. By pressing the “Start” button, the spray gun automatically descends, performs tare weighing of the empty barrels, and then proceeds with dual-speed or triple-speed filling, guaranteeing high filling accuracy. Once filling is complete, the spray gun automatically retracts outside the barrel. The operator then moves the spray gun to align it with the opening of the next barrel and presses the “Start” button again... and so on, until all barrels on the same pallet have been filled, thus completing one full cycle.
Scope of application
The liquid filling scale precisely dispenses large quantities of bulk liquid materials by weight into various containers, iron drums, or plastic buckets. It is used for automatic, quantitative filling of drums ranging from 30 L to 1000 L and is widely applied in industries related to liquid materials, such as chemical, grain, and pesticide processing. This equipment is suitable for products including coatings, paints, inks, adhesives, curing agents, resins, dyes, cleaning agents, motor oils, glycerin, lubricants, edible oils, fragrances, solvents, additives, food additives, pesticides, and other hazardous chemical products.
Functional Features
Product Settings – Store up to 10 different product weight setpoints and their associated filling parameters.
Human-machine interface—The scale can be conveniently calibrated on the weighing terminal; filling parameters can be quickly set on the touchscreen (optional).
Drop Compensation – Automatically adjusts the lead time after each barrel is filled, ensuring that the filling of the next barrel is closer to the target value.
Tolerance check – Checking the tolerance of a full bucket can effectively prevent material overflow.
Data statistics—includes cumulative weight and cumulative count; can be connected to a computer for data management (optional).
Multi-stage filling—can be configured in two stages (fast/slow) or three stages (slow/fast/slow), significantly improving filling accuracy.
Flow restriction device—effectively prevents splashing caused by high initial pumping pressure when filling low-viscosity products.
Drip-proof—The high-viscosity spray gun addresses dripping issues during the filling of high-viscosity products, while the low-viscosity spray gun features an automatic oil-drip cup and a gas-collection hood.
Barrel-impact protection—prevents damage caused by misalignment of the barrel opening when the spray gun is lowered.
Filling Mode – The filling mode design allows for filling via the bucket hole, inside the bucket opening, and below the liquid surface. Users can control the spray gun’s lifting speed to accommodate products with varying foam levels (optional).
Solid construction—The parts that come into direct contact with the material are made of 316 stainless steel, while the remaining components are made of 304 stainless steel, carbon steel, and other materials.
Interlocking Safety – Various process interlocks ensure safe operation.
Easy to operate—The filling system is easy to learn and use.
Flexible design—offering various types of equipment and optional accessories tailored to the characteristics of on-site raw materials and container sizes, with a compact structure.
Easy to install—simply secure the equipment to the ground using expansion bolts, connect the material pipeline, power supply, and air source, and you’re ready to start filling.
