Process weighing is a process that includes the weighing of material as an essential part of the production process. The weighing process includes measuring and controlling the level of inventory and bagging or drum filling/dispensing, and also controlling and measuring the mass flow. Measuring- controlling the level of inventory should show just how much of the storage is full and should also show the precise amount of the material that is currently stored in the vessel. The weighing system should be precise and should be plant-noise proof as only then it will be able to show the precise number/amount of the material stored in the vessel. This way of measuring level or inventory is very beneficial as it is the most precise method of measuring. Weighing is non-contact way of measuring level and it doesn’t cause contaminations.

Filling, dispensing and batch weighing, done by different processes still can provide the same level of accuracy, even if their speed requirements are not the same. The weighing system is required to accurately detect changes in weight in order to provide precise weight cutoffs, monitor the weight thoroughly and often, compensate for system delays, provide a consistent system response, monitor for slow or blocked feed rates. The process of weighing is applied in almost all industries as manufacturing operations require this as a necessity. This is why process weighing systems are extremely important. Filling or gain-in-weight is the process of adding of weight to a scale. First an empty vessel is being placed on the scale and its weight is being tarred off so that only the net weight of the inventory is measured. Dispensing also known as loss-in-weight is the process of removing of weight from the scale. Batching and blending involves weighing of one or more ingredients in one vessel and then further discharging the blend. Measuring and controlling of the mass flow involves weighing the amount of material which is inserted into the vessel or dispensed in a certain time-span. The process weighing systems can accurately measure the level or inventory regardless of the materials.

This means that whether a material is settled unevenly or has changes in density, weight is a constant and in that manner no change of shape will influence the weight of the material which is being process weighed. Process weighing systems are an essential part of every production as such should be accurate and should provide precise weighing results. However, you should keep in mind to calibrate your scales on a regular basis as this could greatly influence the outcome of the weighing process. Today’s weighing systems consists of electronic instruments do not require constant calibration however they should be calibrated often. This means that the calibration could be conducted on a monthly or a weekly basis. Random scale errors are not unusual and they can sometimes occur due to different influences. If a scale requires regular calibration then is should be checked properly as it may have some issues. Regular calibration sometimes is needed if you aim to gain precise results.
