A flow scale is designed to accumulate weighment data on bulk materials. Although this scale is not NTEP certified, it is a highly accurate conveyor scale with an error rate of one percent or less!
The conveyor flow scale operates continuously as material flows across the conveyor. It simply grabs the weight on the scale at specified points of belt movement. The points are electronically encoded according to each complete revolution of the conveyor belt on the scale itself. The tuning-in of this process with the actual product is what provides the accuracy you are looking for.
The flow scale is customized and manufactured according to the type of product, the flow speed of the product, and of course the environment in which it’s to be utilized. For example, design may be for an area of intense wash down requirements in a food processing facility. Thus, construction would be required to be of USDA-approved materials. Regardless of the area of use, stainless steel is the material of choice for strength and durability.
The outstanding feature of a flow scale is that it weighs inconsistently spaced product. Product could be in a granular form in a constant flow or singular items progressing on the conveyor at a rapid pace, but in chaotic form and space.
Although the flow scale is designed for unattended operation, visual inspection should occur periodically to account for possible product buildup. Even though automatic weight zeroing does occur at consistent intervals, one should always strive to eliminate any possible problem areas affecting weighment.
Flow scales gather weight information as desired over specified time periods. This information can be displayed as necessary, or utilized in a control system.
A conveyor flow scale can be a valuable tool as you strive for efficiency!
