Enhance efficiency with flow scales from Jesma

Flow scales like Jesma's JesFlow, JesImpact, and VPR impact weigher are designed for weighing product flow and ensure efficiency in measuring materials. These flow scales is recommended for weighing of product with constant density and products with constant material flow. The concept behind using a flow scale involves material being fed through the inlet at a consistent flow, striking an impact plate. As the material hits the impact plate, the weighing system detects the horizontal force via the load cell, transmitting this signal to the amplifier, which then displays the measurement.

What’s important when weighing with a flow scale?

When using a flow scale, several factors are important for accurate measurements. It is important to have constant material flow to ensure reliable measurements and the material must maintain a steady flow. The material needs to have the same density and properties. If they vary it will influence the accuracy. The material should also be free-flowing and not prone to packing or fluidization/ventilation, which can affect the accuracy of measurements. The flow scale should be free from discontinuous internal air flows, as these can interfere with the weighing process and compromise accuracy. By adhering to these considerations, users can optimize the performance of flow scales and achieve the best weighing result.

What is a flow scale?

The flow scale is a precision instrument used to measure the flow rate of bulk materials, such as powder or granulated products, as they move through a processing system. Key product details of a flow scale typically include its capacity, accuracy, and the type of materials it can handle. These scales are essential in production environments, where space is limited but precise measurement of a product flow is required. This is often necessary for dosing of other products or general regulation. Key componenents of a flow scale is its ability to measure using mass. The scale, build around high-precision load cells is mounted in a parallelogram, which isolates the load cell from the mechanical structure.

The advantages of a flow scale

A flow scale offers numerous advantages, particularly in enhancing quality control. By providing precise measurements of bulk materials, it ensures that the correct quantities are processed, leading to consistent product quality. The accuracy of a flow scale is crucial, as it delivers exact weight measurements, which are essential for maintaining the integrity of the production process and minimizing material waste. Additionally, a flow scale helps regulate the flow rate of materials. This control is vital for maintaining a steady and efficient production line, preventing bottlenecks, and ensuring smooth operations. Overall, the use of a flow scale significantly improves quality control, accuracy, and flow rate management, making it an indispensable tool in various industrial applications.

The different types of flow scales

Flowscales come in various types, each designed for specific applications. JesFlow scales use centrifugal forces and are ideal for any vertical process line of dry, free-flowing products. They feature a compact design with limited build height, making them easy to integrate into projects where space is limited. The VPR JesImpact is easy to retrofit into existing product lines. It's designed for in-line and continuous weighing of bulk materials. It can be applied in any vertical process line that handles dry and free flowing products. The JesImpact utilizes only horizontal forces, making it so any material deposits on the weighing plate will not affect the weighing accuracy. The JesImpact also features overload protection on the load cell, and inspection hatches with dust-proof sealing and inspection window.

The difference between continuous weighing systems and batch weighing systems

A continuous weighing system is defined as a system where material is weighed while moving through the process without stopping. The system measures the flow rate as the material passes through the process without stopping. The system measures the flow rate as the material passes, providing precise control over the amount being processed. This definition applies to industries like bulk material handling, food processing, and mining, where controlling and coordinating material flow is essential to maintaining efficiency and quantities produced. In contrast, a batch weighing system, such as a hopper scale, weighs a specific amount of material at a time. The material is collected, weighed, and then released once the target weight is reached. Batch weighing systems are used in industries that require exact coordination and precision in the quantities produced for each production cycle. This ensures consistent quality and accuracy throughout the process.
