The water I want at 100 ml/min is currently supplied via a pump (non adjustable) to a constant head (about head hight). It flows out of the constant head through a flow gauge with rotameter (not accurate enough), flow being controlled using a needle valve.
I could in theory I could replace the...
Hi bimr,

According to the data sheet for the oval gear above, it's designed for use on fuel oil, of which Petrol has a lower viscosity. Will get a price.
Cheers
Thanks for all the replys. I don't particularly want to spend more than a few hundred. I'm using it on a 'lash up, for research purposes in the lab rather than out on nuclear significant plant.
I would tolerate a +/- 3 % error if I could source one for around £500
Talking about oval gear flow...
I'm trying to find a digital flow gauge that will accurately measure (+/- 1%) a water flow of approx 100 ml/min. The water flows through 1/4 inch plastic pipe work and is low pressure, around 2 psi.
I've searched high and low and can't find anything suitable. Any suggestions would be...
Hi,
The manufacturer has offered suggestions but no site visit.
Rinsing for longer does not solve the problem. The conductivity settles at around 20 microS/cm. We use DI water to rinse. The new cation resin is a direct replacement from the same manufacturer. It has a different name but has the...
System is: cation anion, co-flow, co-flow regeneration with sulphuric and sodium hydroxide. Fixed volume regeneration not pumped. We have two identical cation/anion streams. The problem is on both streams.
We changed our cation and anon resin sometime last year with an equivalent resin. The...
