Hi,
I'm struggling to find suppliers of instruments for on-line free chlorine measurement in water to ~300ppm
best I can find is ~20ppm from the likes of ABB, Yokogawa, and others
Before everyone says "that's helluva high", it is not for a water treatment application (is for makeup of...
Thanks Littleinch, I didn't think it was that rare a term!
Hadn't considered using an additional restriction, will have a think about that

Just reread my post and it is not the clearest ;o)
Specifically, looking for any guidance or references as to how to handle zoning of a lute type arrangement, failing that opinions and/or any info on how other sites may have done this. Don't want to be chasing shadows OR missing a problem.
Hello all, I have a query for the collective minds.
- UK installation
- very wet biogas pipework at low pressure (~35 mbarg)
- Several condensate collection pots in the piping system
- Each of these has a lute i.e. there is no automatic or manual control of liquid discharge, simply the...
hi guys, thanks for taking the time to comment.
Latexman - the proposed solution would eliminate the plate altogether and use routing valves so the person would not have to be anywhere near - and there would be no swingbends involved. Specific PHA / PSM requirements (I had to google) are not...
Hi Latexman,
Routing manifold for transferring fluids between different locations using a swing bend or flexible hosehttp://www.pipeline-products.co.uk/media/images/news/700/94240_flow_plate_010.jpg
Hi there,
I'm trying to find out if there is any guidance - regarding when it is would be recommended NOT to use a flowplate / dial-a-pipe type arrangement for routing flow.
I have a flowplate in a food factory that has 4" piping and line pressures of >8 bar during the cleaning cycle (of 80...
I've not worked out how to edit posts - should have said "my poor knowledge of compressible flow"

Hi all
Thanks for all these replies!
I've had a play about with what I can easily calculate without getting into too much complex heat transfer theory - it is a while since I had to do that kinda maths - and then come back here to see Stonecold's suggestion which is near as dammit what I came...
Hi Latexman, were it not for the fact that I have >20 existing tanks, I might agree!
I know there are similar arrangements of hot CIP, cold rinse in many finished product storage tanks in the food industry, also e.g. road tankers for food products, but I can't find anything to define a sensible...
Thanks KvdW, sadly I don't think it does - the closest would be RJB32482's point but I can't see how to apply that equation to my problem (I may be daft, or over analysing it) as I think it is looking at heat losses from the tank causing the condensation, whereas I have an inflow of cold water...
Hi folks,
I've been googling like mad for this, all I can find is various works for when there is cold spray on the outside of the tank surface condensing steam inside a tank... Any hints as to where I might find a solution more related to this particular problem?
Cheers
Col
Thanks guys for taking the time to view the thread.
Some additional info I did not include in the original query as I thought it muddied the issue, I guess being from a food / pharma background I forgot that other industries don't necessarily have the same problems/situations and my wording...
cheers for that... but you can't have a manway open when you are high pressure sprayball cleaning the inside with 80 degC caustic solution...! we'd soon have a 10m spray of caustic across the roof of the factory! ;o)
Hello all,
I've seen a few similar-but-not-quite-the-same threads so here goes.
I'm trying to confirm size of a vent in a ~70 m3 atmospheric tank which sees a range of temperatures and is also cleaned at 80 degC followed by a cold rinse. (There's direct steam injection too but I'm trying to...
thanks folks for quick response! Most valves are butterfly, no threaded bits (all welded except a couple of hygienic unions). Will keep an eye on it rather than scream!
Hi,
A contractor has installed a section of pipework, control valve, flowmeter and isolation valves in 316 stainless steel (may be 316L not sure). The duty will be saturated brine at ~10-20 degC. It is ~1" line and will see a reasonably constant flow for most of the time but possibility of...
