How to Troubleshoot Your Feeder for Optimal

There are two types of weighing technology typically used in LIW feeders: analog strain-gauge technology and digital vibrating-wire technology. The key is that the higher the resolution of weight measurement and the faster those weight measurements are taken, the better the information that will be provided to the control algorithm and the ...
