Excerpts:

Before: “We had to go out every two or three weeks to download data from the monitors we had. Commonly, we’d install a flow monitor, the sensor would foul up the following day and then we wouldn’t get out there for another three weeks to check the monitor. We were losing data...”

After: “The data is sent wirelessly to our computer, and we can access the data from anywhere online – even from home. We don’t have to transport large amounts of data back and forth.”
