R/C flowmeter....

[Redux]

has anyone found a local supplier of these?

:text-thankyoublue:

[rumdidlydum]

Total eden springs to mind but unsure if they have them :think:
I know fleabay has them

[scythe]

Just make sure you get one that has a suitable flow range.
The people that have the on the forum seem to find that a 2Gal/min scale gives the right resolution range.

These seem to be popular:

exactly what i had in mind... the r/c coolant circuit has a full flow bypass for 100%reflux and an aux circuit with this meter in it for the run....

all the ones i have seen are in hong kong... anyone found an aussie one?

[scythe]

Not much chance of that on ebay lately.
You might get lucky as a pump/irrigation shop or somewhere that sell water tanks, but more than likely they will only have higher flow rates.
But probably not a cheap item from a bricks and mortar shop.

This looks usable.
"cliquez sur-moi"
No idea on price tho, looked in the green shed this arvo and they didn't have any

Hey Anyone know where I can get cheap water flow meters?

[Meatheadinc]

I have a 0.5gal/min 2L/min and its the one you want. Also have a 1gal/min 4L/min. Its not as good. Both from fleabay.

By using both in series ( 2gal before 0.5gal) i found that you can exceed the 0.5gal/min on the 0.5gal unit for extra flow but it has great resolution at lower flow.

Also played with hall sensors and found them ( ones i tested) to have poor resolution at low flow.

[scythe]

So by hall sensors you mean the ones with the little impeller and needs to be hooked up to a screen to get the read out, yes?

I have thought about using them so im glad you got there first.
Saved me time, money and frustration.

Those flow meters seems to have gone up in price since i last looked for them.

The simple flow meter is good for a visual indication of flow through RC but is anyone using a flow switch (or pressure switch) for alarms? I cannot hear if my pump is running so would like to have an alarm rather than just watching a flow meter or worse still waiting for the vapour to come pouring out.

A PdT would be nice but there doesn't appear to be a low cost solution.

Yes

@GroggyAl.
I have a paddle switch on my Product condensor that triggers a normally open contactor block that both elements pass through.

If on gas a solenoid valve could be used in the same fashion.
No waterflow=No Element power.

I just ordered this one:

It's two lpm which is about perfect for my setup. I've been using a 9 lpm model but it spends the whole time just above the bottom.
I'll need a bypass for full reflux but should give more helpful readings. :handgestures-thumbupleft:

you guys have no worries ordering from china?

[res]

Ethical or financial?

Bit of yes no for me. But needs must when the devil drives. ;-)

financial.... you hear bout stuff not showing up.... i wonder why no-one here sells em?

[Meatheadinc]

@res I have a similar one to your link although it has a needle valve built in.
It will flow over 3 liters with adequate pressure (weight hits the top) so you probably dont need the bypass.

:laughing-rolling: That's hilarious, didn't even notice it didn't have a value. Looked just like my other one, and did seem a little cheaper. :scared-eek: No more late night ebaying. :?
I've been meaning to pressurize the loup and control the flow via output. Looks like thats moving up the priority list. :D

Cheers Meatheadinc.

Here is an Aussie company that has a very wide range of flow meters;

:handgestures-thumbupleft: cheers!! so many choices!!

[GroggyAl]

This one would be nice to give both visual indication and also alarm switch which could shut down main element contractor.

I'll use an old Pd switch I have in my junk box for the time being along with the low level switch in my 30L tank.
