Weighfeeders
The Series 400 Weighfeeders are used to add lime during the water treatment process
The Series 400 Weighfeeders are used to add lime during the water treatment process. The lime is added to adjust the pH of the water. The remote set point for rate control on the weigh feeder can be slaved to an online pH meter.

The weighfeeder delivers the lime to the water in a controlled, uniform flow rate with +/- 0.5% accuracy.

The constant belt-tensioning device allows the Series 400 weighfeeder to be used in low density and low flowrate applications. It provides the capability for relative light belt loading. In addition, the product also has a large platform weighbridge area that offers a greater size of sample material.
