Choosing a dynamic belt weighing system isn’t as simple as just perusing a catalogue. There are a number of factors you need to consider before making your selection.

For example, there are many different types of dynamic belt weighing solutions, each of which is designed to accommodate a specific process. In addition, the layout of your facility will determine which systems are feasible.

Here are three steps you should take before choosing a belt weighing solution:

1. Know the different types

The Institute of Measurement and Control, an organisation located in the UK, noted there are three broad categories of dynamic weighing systems. Each of these classifications encompasses different devices which are optimal for some applications but inappropriate for others:

  • Discrete mass delivery weighing solutions weigh volumes of material by “batches”, assuming those batches will be either put into a container for storage or blended with other substances.
  • Discontinuing totalising weighing systems deduce the sum total of multiple batches, and are typically used to record production. 
  • In-motion weighing solutions calculate the weight of a mass moving over or through a particular device.

2. Gather process data 

Break down your process into individual parts and identify the constraints. This step entails answering a number of questions, such as:

  • What are its limitations, and how do they dictate how material should be processed? 
  • What type of material is your facility handling?
  • Are mixing and batching part of your operations? 

If you think it necessary, it may be best to contact industrial measurement instrumentation consultants to gain their input. These professionals will conduct audits of your site, identify opportunities for production enhancement and make recommendations that implement those improvements.

3. Understand how they work 

Knowing how belt weighing solutions work can go a long way in helping you make the best choice. 

Weigh feeding is based on gravity. The measurement devices calculate the weight of a mass over the span of a conveyor belt. In some cases, the “span” is the space between a scale approach idler and a scale retreat idler. There are weigh feeders that incorporate suspension idlers in the middle of the span. Overall, the array enables dynamic belt weighing systems to accurately deduce the weight of a material in motion. 

Ultimately, it’s best to work with professionals who specialise in commissioning, repairing and servicing these instruments. If you want to get in contact with such experts, speak with SRO Technology today.
