Deciding which liquid filling machine to buy usually comes down to a trade-off: throughput, fill volume, and how much hands-on attention you want to give the line. The four machines in this comparison are listed between $150 and $546.55, and they cover continuous work, multi-head filling, small-bottle filling, and weighing-based dosing. If you need to fill thousands of bottles, a conveyor and multiple nozzles matter. If you need accurate doses across a wide range, a weighing filler can be the simpler route.
Quick Take
The weighing bottle filler is the only unit here that doses by weight, and it reaches 5000ml. The six-head digital control model gives you six nozzles and a semi-automatic workflow. The continuous single-head filler is listed as full automatic. The four-head model is built around a smaller bottle range and sits at the top of the listed price spread.

Product Notes
Automatic Continuous Bottle Filler 3000ml
This single-head filler carries a 15kg rated capacity, a 12x120cm conveyor belt, and an accuracy rating of ≤±1%. For someone filling water, juice, oil, or perfume in medium-to-large bottles, the full-automatic workflow is the main draw: you set the fill and let the machine handle the line. The 304 stainless steel construction is a practical fit for regular food or cosmetic bottling. The limitation to keep in mind is the single 8mm filling head. If you need to fill many bottles at once or change products quickly, a multi-head or weighing-based design may be more flexible.
6 Heads Digital Control Bottle Filler 2000ml
If you want a middle path between a single-nozzle line and a multi-head setup, this six-head semi-automatic machine is built around speed without taking over every step. It has independent speed control on each head, a digital panel, and a 5-2000ml range. The 304 stainless steel and silicone materials should hold up well with a variety of liquids. Six heads also mean you can fill multiple bottles at once, which helps when you have steady daily batches but don't need a continuous automated line. The trade-off is the 2000ml ceiling and semi-automatic operation, so you will be guiding bottles through rather than running an automated line in one pass.
4-Head w/ Belt Conveyor 10-500ml
This model combines a belt conveyor with 1-4 adjustable filling nozzles, making it suited to smaller bottles in the 10-500ml range. It is a 110V, 150W tabletop machine with a diaphragm pump and PVC/stainless steel/aluminum construction. The adjustable nozzle count is useful if you need to switch between lower and higher output on the same setup. For beverage or cosmetic samples that come in small bottles, this format lets you combine conveyor movement with multi-nozzle filling. The biggest constraint is the fill volume ceiling: at 500ml it cannot handle the same bottle sizes as the larger fillers in this group. It also requires assembly, so budget some setup time.
Weighing Bottle Filler 20-5000ml
The broadest fill range in this group belongs to this weighing bottle filler, which lists a 20ml to 5000ml capacity and a 10kg weighing range with 2g scale divisions. Because it doses by weight, it can be a good choice when consistency matters more than raw speed. The diaphragm pump moves up to 10L per minute, and the filling head adapts from 0 to 40cm. It is intended for low-viscosity, non-solid, non-corrosive liquids such as water, drinks, and wine. If your product is thicker or contains solids, this is not the machine to start with.
Final Recommendation by Use Case
If budget is the first constraint, the model with the widest fill range and a built-in scale is the entry point. If you run medium volumes and want more nozzles, the digital control model with multiple heads is the natural fit. If you want a continuous process for larger bottles, the single-head continuous filler is built for that rhythm. And if your bottles are small and you want adjustable nozzles, the tabletop four-head model is the one to build around.
