I am working on an experimental system for a new chemical a supplier of a client of mine has invented and my customer is going to be their Guinea Pig.
The chemical needs replenished based on Amp/Hours applied by 2 rectifier power supplies. But the replenish is not a chemical metering pump I can control the pulses and check for flow out of the pump - it will be a dry powder added 148 grams each replenish.
The control will be run an auger motor for x.xx seconds to get the precise amount of powder. OK with me so far.
My issue is there isn't any monitoring of output to ensure the powder is actually dropping into the tank. The amount is about 5 ounces, so I was thinking drop the powder into a scoop or trough that trips a switch at over 4 ounces, then after the auger stops dump the trough. Not 4 ounces means drive failure, powder bin empty, fuse blown, etc. - set an alarm.
Has anyone ever used a monitoring system similar to this and know who has them? Or am I going to have to design one myself? I don't want to just run it and at the end of the day find out the system wasn't working.
