I may not be understanding your problem correctly, but here's what I think you want:
Write a program that runs in the background that grabs the info from your online data source (the flow meter) every x number of seconds/minutes.
Store that in a database along with a time stamp. (can be a system file)
Your quiry checks your local database (or file) for the information to display to the screen.

I will try to explain using thr following example.
1. Speedometer of your car.- We are travelling in a car and our speed is constantely varying due to traffic conditions. But at the end of a time I would like to know the exact distance travelled. WE get this data from the speedometer directly. Such a speedometer I would like to create using a program.(VB)

Oh, I see.
In that case: (using the speedometer analogy)
(seconds/meters per second)
3/12 (3*12 = 36 meters)
2/6 (2*6 = 12 meters)
4/16 (4*16 = 64 meters)
3/14 (3*14 = 42 meters)
3/13 (3*13 = 39 meters)
total: 193 meters in 16 seconds
