Can venturimeter & orificemeter be used for low Reynolds no. flow?

Question

If wanna avoid the low Reynolds no. when monitoring low flow rate, how to overcome it?

Answer 1

if you size the orifice correctly, you should be able to get significant pressure drop, even at low pipe velocities

if you get enough pressure drop in your orifice, then you can get a reasonably accurate velocity estimate

the reynolds number in the pipe is not the issue, the reynolds number in the orifice or venturi must be high

there will of course be some pressure loss, orifice meters use permanent pressure loss for the measurment

with venturimeter there is less permanent pressure loss

Answer 2

I have no opinion the two for or against low-bypass bogs...I do think of they could be solid for our surroundings and our sea creature acquaintances. asswhore? is which you thumbs downing? I also have a feeling that's =(
