re: Flume water meter monitor

Pipe diameter is a constant.

I don't know much about engineering but is max flow rate a constant even under different pressure?

Calculating the movement of water under the sensor is the tricky thing to me.

If a smart faucet can reliably deliver precisely 1 cup of water every time there must be a simple sensor somewhere.

I'm overthinking this for sure but the movement of water through the pipe is what I don't get. How can an external sensor get that data unless it's "stealing" it from the existing meter somehow.
