For some products they can be accurate enough to keep in your process and deal with their calibration issues, but for some products, they can be a maintenance nightmare and something that needs to be replaced. However, with their large footprint and complex installation, finding a replacement feeder that fits can be a real issue.
One way to deal with this maintenance issue but to still have that vital process measurement is to install a flow meter that can be installed at the end of a belt conveyor. Since the Weigh Belt is in essence a belt conveyor, it would be used as just a material handling device and not a flow meter. Once such a device that can fit in such a tight space is the CentriFlow Type I meter from Eastern Instruments.
The Type I meter is designed to be fed with a horizontal feed device like a belt conveyor or vibratory conveyor. For a belt conveyor, the meter can be positioned just at the end of the belt and the trajectory of the product flow off the belt will allow it to slide through the meter’s flow surfaces, providing excellent accuracy. The graphic below shows an example of how the meter would look installed at the end of a belt conveyor.
