Automatic Checkweighers

An automatic checkweigher weighs products as they move through the production line, giving rapid, in-motion measurement without stopping the item. A static scale, on the other hand, requires each item to be placed on a stationary platform and weighed individually, which is slower and not suited to high-throughput environments.

Accuracy depends on the model and application, but modern dynamic checkweighers typically achieve precision in the range of ±0.1g to ±5g or better. Calibration, conveyor speed, product stability, and the surrounding environment all play a part in the final accuracy achieved.

Checkweighers play a vital role in ensuring product quality, consistency, and compliance across production lines. By automatically verifying that each item meets its target weight, checkweighers help manufacturers reduce waste, prevent costly product recalls, and maintain adherence to industry regulations. They also improve efficiency by identifying under- or overfilled packages in real time, allowing quick adjustments to filling or packaging equipment. Ultimately, checkweighers support better quality control, increased productivity, and greater customer satisfaction, which makes them an essential part of any modern manufacturing process.

Yes! Our systems are designed for easy integration, mounting into most conveyor setups and connecting to control systems like PLCs, MES, and ERP through standard communication protocols.

Yes! MWS can provide leasing plans to spread the cost of capital equipment over a number of years, making it easier to invest in the right system for your line. Contact us for pricing on automatic checkweighers.

Definitely! If there isn’t a standard checkweigher in our portfolio that suits your needs, MWS can design and manufacture a system to fit almost any application, so you’re never limited to an off-the-shelf solution.

MWS is the UK distributor and service partner for Prisma Industriale, whose checkweighers are designed and manufactured in Italy using recognised parts, keeping service simple and cost of ownership low. We also supply a range of checkweighers from A&D, covering everything from compact benchtop units to heavy-duty, high-capacity systems.

Yes! MWS provides UK-based installation, calibration, maintenance, and support services, helping to keep your checkweigher performing at optimal levels throughout its working life.

Yes, indeed! We offer stainless steel and IP-rated models designed for harsh environments, including washdown cleaning and dust-prone areas commonly found in food and pharmaceutical plants.

It comes down to a few key factors: product weight range, line speed, product dimensions, required accuracy, environmental conditions such as washdown, temperature, or dust, and your data connectivity needs. Our sales engineers are happy to help with specification and customisation.

Absolutely! Checkweighers help ensure products comply with weight regulations such as UK Weights & Measures and EU Directives by automatically rejecting products that are under or overweight, supporting the Three Packers Rules that apply to declared pack weights.

Dynamic checkweighers are widely used across food and beverage processing, pharmaceuticals and healthcare, packaging and logistics, chemical production, and automotive parts and manufacturing.
