Dry bulk solids are the most commonly used materials in a majority of items of daily use around us. Plastics, food products, fertilizers, cosmetics, pharmaceuticals, building supplies etc are all manufactured from various combinations of dry bulk solids or granular material. The industries that manufacture such products function on the basis of profitability and hence, they need to ensure that their processes are efficient, cost-effective, labor-saving, reliable and consistent.

Manufacturing industries typically conduct in-depth studies of their processes so that they can be fully optimized. Each and every process is thoroughly examined so that the input-output ratio is balanced. The best settings for each piece of powder handling equipment, ingredient-mixing ratios etc for maximum output at minimum cost are some of the important things that manufacturers focus on.

Dry Bulk Solids

Solids come in all shapes and sizes, different textures and degrees of hardness/softness. Unlike liquids, they hold their shape, because their molecules are packed tightly together, arranged in different patterns or arrangements of atoms. Solids can be combined, to make mixtures and each individual component remains separate, while forming the whole.

Manufacturing processes in the pharmaceutical, food, building-supplies and cosmetics industries involve the use of transportation and mixture of dry solids in bulk, usually in powder form.

These processes require high levels of accuracy. Hence, the use of powder flow tester and flow measurement devices becomes crucial in maintaining the integrity of the end products.

The Importance of Flow Measurement Devices

Some reasons for inaccurate flow of bulk solids may be that the measurement technology selected is inaccurate, there's insufficient space for installation, the product being measured sticks to the measurement device or the measurement device itself gives inaccurate results due to wear and tear.

When the powder flow instruments become unreliable, the entire manufacturing process can come to a standstill.

Selecting the right powder flow tester is the key to the proper functioning of your powder handling equipment. The flowability tester that you choose is based on what your requirements from it are, and also at which point during the process you want the measurement results to be provided.

If the powders are pneumatically conveyed, the best meters are those that use radar, Doppler or nuclear technologies. For static solids that are not in process, as in silos, trucks, etc, dynamic flow meters or static weigh scales can be used. Gravimetric flow meters are another option which allow real-time, actual measurements.


A thorough, in-depth knowledge of all aspects of the process is essential before you select the right flowability tester. It's also important to understand the functionality of the different types of testers available and which one is most appropriate for your particular process.
