Product Introduction
The FWS-30E1 liquid quantitative electronic filling scale is a semi-automatic liquid filling scale designed for the automatic weighing and packaging of liquid materials in industries such as chemical, grain, and pesticide production. It employs a highly precise, all-electronic weight detection method to accurately measure and control the automatic, quantitative filling of raw material drums. With its high degree of automation, this equipment minimizes material spillage, effectively prevents contamination of the surrounding environment by the materials themselves, and thus 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 process control 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. Both feature a special clamp-type connection structure that makes them 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. Its design is compact and well-organized, ensuring efficient operation.
It is stable and reliable, easy to install and operate, and can be adjusted accordingly to suit various on-site conditions and production capacities, thereby meeting user requirements.
Scope of application
The FWS-30E1 liquid quantitative filling scale precisely dispenses large quantities of bulk liquid materials by weight into various containers, iron drums, or plastic buckets. It is designed for automatic, quantitative filling of drums ranging from 1 L to 30 L and is widely used 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.
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 nozzle addresses dripping issues during the filling of high-viscosity products, while the low-viscosity nozzle 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.
Quick replacement—All connections in the conveying pipeline use quick-connect fittings, making it easy to quickly swap out spray guns.
Filling nozzle—The corresponding filling nozzle can be easily replaced according to the caliber of different containers, making the operation process more convenient (optional).
Automatic hole alignment—many filling ports on cylindrical containers feature eccentric holes. This technology can address the inconvenience of manual hole alignment (optional).
Filling Mode – The filling mode is designed to support top-fill, internal-fill at the bucket opening, and sub-surface filling. Users can control the spray gun’s lifting speed to accommodate products with varying foam levels (optional).
Solid construction—parts in direct contact with the material are made of 316 stainless steel, while the remaining parts 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.

Filling method: Simple type
Filling specification: Single nozzle, single barrel
Spray gun structure: Ball valve (304 stainless steel)
Material interface: 1" NPT or DN25 flange connection (material inlet pressure < 6 kg/m²)
Material viscosity: 3000 CPS
Filling range: 5–30 kg/can
Filling speed: 3–6 (the material flow rate in the pipeline should be ensured to reach 180 L/min)
Filling accuracy: 0.2% (accuracy depends on the adjustment of slow feeding as well as the continuity and stability of material supply).
Filling container type: 20L small-opening can/open-top can
Air source pressure: 4–6 kg/m² · Air consumption: 50/min
Power supply voltage: 110/220 VAC · Power consumption: 0.5 kW
Working environment: Temperature: -20℃ to 45℃, relative humidity: 95% (no condensation).
Hazardous Area: The FWS filling system can be used in Class 1, Division 2 hazardous areas of Groups A, B, C, and D, with an explosion-proof rating of ExdIIBT4.
Note: The FWS-30E1 liquid quantitative filling scale is standardly equipped with a single-gun filling machine. If multiple materials need to be filled and they cannot be mixed or come into contact within the spray gun, the machine can be upgraded to a dual-gun filling machine. If the filling speed needs to be increased to 6–9 cans per minute, the machine can be further upgraded to a dual-bucket filling machine.
