sorry Ivo, I don't understand the question

the flow rate was measured with a Danfoss MAG 5000 flowmeter with MAG 1100 ¼in. magnetic flowtube (±1/2% of reading accuracy)
- magnetic flow meters read the velocity which must be within a certain range, had I wished to measure higher flow rates I would have used a larger flow tube (which I have up to 2" ID, and positive displacement pumps to match)

pressure drop with a Foxboro 823DP differential pressure transmitter and Digitek digital gauge (~±1 to 2% accuracy)

the pressure drop is accurate over the flow rates shown, and as Cathar has pointed out will increase exponentially beyond the flow rates tested
