@artisi: Doesn't the pitot tube require a certain pipe length for laminar flow? Any Idea what it costs when flow is 4000 m3/hrs and pipe dia is 630 mm?
@3DDave: The pipe is somewhat higher up so it sucks in some air.
@Danschwind: 100% gravity. 300 mm difference in water level. Bernoulli?
@Artsi,
the problem is our piping is rather large (ø630 to ø1200) and clamp-on flow meters typically require 15 DN lengths straight pipe for accurate measurements. I don't have that at all.
A 10 pump system flows around 4000 m3 per hour, and that is a small-medium size system for us...
Hi.
I have a pumping system with say 10 pumps (pumping from the same tank) connecting to a manifold which sends the water to some other tanks.
If the pressure on the manifold is known, and I measure the power consumption on each pump, then I should be able to read the flow rate on each pump on...
