Water flow sensor

[Pocster]

Googled this but couldn’t find anything .

I thought it would be really good to trigger my Mvhr to boost on water flowing for certain items .

So a ‘device’ clamped on the shower feed Hep2o pipes , or maybe on the toilet feed . So when in use I can trigger a relay to boost mvhr . I know I could go off motion but I’m trying to be more specific- as I have a manifold of manifolds it makes access easier .

There are ultrasonic sensors that are non-invasive for water pipes.

Look for something cheaper though.

 

You may find that a couple of temperature sensors set up differential may work.

Perfect! Until I saw the price !!

I suppose an inline Hep2o one would be nice and cheaper !!

Shall investigate ! . I reckon it’s the type of thing @Onoff would love to make .... ?

Found some on eBay for £10

Certainly not clear exactly how they work - I presume it’s just a relay . Stick a current down it and if there’s flow ;circuit is complete ... . Worth a look at later - then I can bill SWMBO when she fills the bath up !

Ok

 

Why aren’t you working ? - just reading my crap .

Why not use a RH sensor in the extract duct like most do.

There’s a sensor on the mvhr . As I haven’t used it yet I was concerned how long it takes before it activates . Just thinking ahead ?

I think it was a couple of years ago I was mulling a flow switch placed in line to the rainfall shower head. It would trigger a ring of LEDs set in a circular pattern around the shower head...maybe in a like Knightrider sequence. To get the full effect I need the noise from the Stargate transporter rings.

And why didn’t you do that ? ?

[Temp]

Perhaps something like this (it not a clip on though. You need to cut pipe)..

same for

Other people thought is was a silly idea, along with the rise and fall shower head.

 

As your mate said "The people who are crazy enough to think they can change the world are the ones who do".

Then stop fecking about and do it this weekend ?

Put in some really powerful UV LEDs, that will kill all the germs.

And like all boys in the shower, spending too long in there 'washing', will make you blind.

if I jump in the shower mine comes on within two minutes, only problem is the ambient RH sometimes confuses it, @Jeremy Harris said he adjusted his winter to summer.

Be worth it just for my lads reaction when he comes back from uni. Big Stargate fan he is.
