Loss-in-weight feeder for liquids
Achieve precise and continuous liquid dosing with high accuracy, adapting seamlessly to your specific processing requirements for improved product consistency.

Accurately Doses and Weighs Liquid Ingredients
The Loss-in-Weight Liquid Feeder from SPS | Solids Process Solutions incorporates a digital load cell weighing system, DigiMASS-2, ensuring unparalleled accuracy in dosing various liquid ingredients. This feeder is particularly suited for industries such as aquafeed, pharmaceuticals, and food production, where precise measurement is critical. Its working principle relies on a digital load cell to constantly measure the weight loss of the liquid, adjusting the feed rate for consistent output. It’s compatible with different pump types—piston, diaphragm, gear—and offers heated versions for temperature-sensitive materials. With seamless integration into existing processing lines, it supports continuous high-precision operations, emphasizing efficiency and reliability. The equipment’s construction options include materials that resist corrosion, suitable for harsh chemical environments, and are compliant with industry standards. Additionally, its design facilitates ease of cleaning and maintenance, ensuring long-term operational stability and minimal downtime. Customization options are available to tailor the equipment to your specific process needs, supported by comprehensive engineering expertise from SPS.
