how can i obtain the pump flow rate ?
is this done by filling a certin volume and measure time or there is another method ??

Pump curves from the manufacturer is the best way. The pump head and flow rate are related so you'll need to have the curves.

You can get the rated flow rate by using the bucket and stop watch method though!

Pump flow rate can be obtained by following engineering device:
1. for low flow, electronic meter with a propeller will help you; cheapest flow meter.
2. for high flow, pressure diffential device is a mechanical choice.
3. eddy current flow meter, easy to use, no skill is need but very expensive.
