Hello again,
I was informed today at my job that one of our Raw silos does not have a high level/overflow sensor to stop any product from overfilling the silo. This is only a concern every once in a while when we have heavy receiving traffic from tankers.
What ends up happening is the product reaches the overflow pipe, and starts dumping down a drain. There is a sensor at the bottom of the pipe where the actual drain is, however for this sensor to trigger an alarm it takes almost 300 gallons. Obviously not cost effective, I was unaware of this until now and I was told to fix this issue.
They are looking for a fix that I can apply to the PLC, which I dont' see an issue with I was just coming here to see if my idea was a good fit or if anybody else has any insight on may be missing.
We have a meter that counts gallons received on the truck side that I can use as well as the Raw Receiving tank's level sensor. My thought is to compare the levels after a while or once it becomes closer to the tanks capacity (within 500 gallons). I would poll it every 5-10 seconds and check the difference between the meter and the level sensor of said tank.
The level sensor would max out and not move, where the flow meter would continue counting and once it becomes further apart I would stop the receiving pump.
My question is does this seem like a sound and logical approach or if I'm missing something what would it be? I appreciate any and all responses as always and if I'm forgetting something I'll add it when I have time.
Thanks again!
Phil
