I would like to take a 4-20ma signal form a flow meter and send the data to Amazon.com AWS so that I can view the data remotely. This is a single or a very few (3-4) points system. I don't have a internet connection so I would like to use a cell connection like a verizon myfi or the like. Is there a device that would digitize the analog signal can transmit the high low and average at a predetermined time interval?
