Hello,
We are a mechanical engineering senior deign team from the University of Houston building an automated beer brewing system known as HERMS (heat exchange recirculating mash system).
We are trying to measure flow rate between tanks and most of the flow meters that I have found that are analog (4-20mA) are pretty pricey and we have little to no budget for too much. During my digging I found something called a flow Transmitter;
http://www.dwyer-inst.com/Product/Flow/FlowTransmitters/Paddlewheel-In-Line/SeriesSFI-800#ordering
From what I can tell it sends a frequency pulse ranging from 1-10VDC, I assume something like a PMW only in reverse.
So to get to the point, one am I understanding how this device works? Two can this be used to measure flow rates? and lastly we were given a Siemens S71200 PLC with an analog module so is there any way that this option can be use?
Also if you have a suggestion one a cheaper flow meter that can read between 0.1 to 10GPM we are open to any suggestions.
Thank you in advance for the help
Team HERMS
