Hey all. Our friend @B.lu needs some help.
B.lu said:
does it seem strange that I would still get flow on the swg at the lowest setting my VSP goes (450). Also, any idea why at 450 the VSP says it uses 135 WT energy but on 38 WT and 39 WT at 550 and 650? Thanks!!!!!

So we have a possible malfunctioning flow switch to activate so low. At least, unless her pool has stupid flow at 450 RPMs with the 3HP intelliflow.

At first I was thinking the LCD screen had an issue and wasn't showing the '1' of 1450 RPMs, which would align with the 135 Watts displayed at supposedly 450 RPMs. 550 and 650 RPMs draw the appropriate wattages.

When she ramps the RPMs up and down by the hundred with the arrows, the motor volume behaves as expected, all the way down to 450 RPMs which draws more watts and still keeps the SWG on.

We polled 100 people and the Top 5 answers are on the Board.

So what is the lowest speed when the SWG flow switch does cut out?

450 is the lowest the pump goes and the SWG stays on. It turns off when the pump is shut off, so the flow switch isn't seized.

And the wattage for 450 RPMs reads 135. Does it get less efficient lower than a certain ideal flow ? I had an Intellepro for 9 years, no, no , not @Jimrahbe. The Sta-Rite clone of this one. Mine was set to 700 RPMs as the low and I never went lower to see the wattages.
 
The AquaPure does not have a flow switch, it has a flow sensor, which is a heated probe and and unheated probe and it works on the same principle as "wind chill".

As long as it shows No Flow when the flow stops, then it is probably Ok.

In my tiny mind, I never want to run my pump if it is not making chlorine and not skimming the pool.

Certainly, the SWCG's flow switch must be closed, but I also want enough flow to allow my skimmers to work. I think today's pumps are more efficient than the ones made 10 years ago, so I am not sure that using RPM as the deciding factor works in all cases.

For me the key is having both the flow switch closed, and the skimmers working well, I don't really care what the RPM or GPM readings are. I'm looking for the results I want, and not a magic number.

Thanks,

Jim R.

Absolutely. We went over that. She was experimenting with 1st full season toys and noticed the oddity. Glad to hear it is all good. Thanks for the assist as always !!!

You too @JamesW, and @PoolGate Much obliged. :)

B.lu will have some good news when she gets off work later.

Thank you guys all so much. Like newdude said, I happened to notice it and was confused. I was trying to find the lowest setting the VSP could go while still getting flow so that I could drop it down that low during the night. My ultimate goal is/was to have the pump run 24hrs a day particularly if I am away for a couple of days and want to have the swg chlorinate the pool. My neighbor wouldn’t mind coming over to flip on the Polaris cleaner every couple of days but I wouldn’t want to also ask for an am and pm drop by for the swg. During the pool build I didn’t really get how helpful automation would be. At this point, I’m years away for being to make a case for any more $$$ to go towards the pool

This TFP community continues to amaze me. You give so much of your time to strangers. It’s inspiring

I think that this is the basic process (or similar) that the Jandy flow sensor uses for its thermal flow sensors.
