On this page you will find Belt Weighing solutions for monitoring constant loads on conveyor systems. These scales are designed to constantly measure flow rate and total load of bulk products as they are transported along a conveyor belt.
Our belt weighing scales are designed to fit under conveyor belts, and can be fitted to existing installations.
The BS143 belt scale weigh frame is suitable for medium to heavy capacity belt conveyors, for high accuracy continuous weighing applications
The BS221DB MASTER belt scale weigh frame is suitable for medium to heavy capacity belt conveyors, for most belt widths and capacities
Easy to install and in standard or custom made dimensions, it easily fits on the conveyor frame by using only four bolts.
Conveyor belt weighers (also called belt scales or weigh frames) are precision weighing systems that fit beneath a conveyor belt to continuously measure the load passing over it. Load cells built into the weigh frame track the weight of material on a short section of belt, combine this with belt speed, and feed real-time flow rate and total load data to a digital display or control system.
The weigh frame replaces a standard section of conveyor idler with a weighing platform, allowing the belt to keep running exactly as before while the load cells capture continuous, in-motion weight data. This means you get accurate throughput figures without ever stopping the belt or handling material separately.
Belt weighers give you continuous, real-time weight and flow rate data rather than a single static reading, so you can monitor production as it happens. This can improve stock control, cut down on waste, support tighter quality control, and make it much easier to spot process issues before they become costly.
They’re widely used in mining, quarrying, agriculture, food processing, manufacturing, waste management, and any industry that relies on conveyors to move bulk materials. Anywhere accurate, continuous throughput data matters, a belt weigher is a great fit.
Absolutely! MWS belt scale weigh frames are designed to fit under conveyor belts and can be retrofitted to existing installations, so you don’t need to replace your whole conveyor system to add accurate in-motion weighing.
In most cases, installation is straightforward. Models such as the BS311 are designed to fit directly onto the existing conveyor frame using just four bolts, while larger systems may need some additional bracketry depending on belt width and capacity. MWS can advise on the best fit for your conveyor and support you through installation.
MWS offers a range of belt scale weigh frames, from the BS311 for lighter to medium duty conveyors, up to the BS143 and BS221DB for medium to heavy capacity applications. The right option for you will depend on your belt width, conveyor speed, and the loads you need to measure.
Belt weighers are built to deliver high accuracy continuous weighing, even under demanding, heavy-duty conditions. Models like the BS143 are specifically designed for high accuracy applications, giving you dependable flow rate and total load figures you can rely on for stock control and process management.
To keep your belt weigher performing accurately, it’s important to carry out regular inspections, keep the weigh frame and idlers clean, and schedule routine calibrations. MWS offers servicing and calibration support to help maintain accuracy and compliance over the lifetime of your system. Learn more about our calibration services.
Yes, indeed! Belt scale weigh frames can be tailored to suit specific belt widths, capacities, conveyor frame dimensions, and indicator requirements, ensuring the system integrates smoothly with your existing conveyor and meets your operational needs.
Conveyor belt weighers, also known as conveyor belt scales or weigh feeders, are devices used in various industries to measure the flow rate and total amount of material being transported on a conveyor belt. They provide real-time data about the weight of the material moving along the belt, allowing for accurate monitoring and control of production processes.
These weighers are commonly used in industries such as mining, agriculture, food processing, manufacturing, and more. They offer several benefits, including:
There are different types of conveyor belt weighers, including:
Overall, conveyor belt weighers play a crucial role in various industries by providing accurate and real-time data about material flow, enabling better process control, quality assurance, and operational efficiency.
