Litermeter3 & topoff module - question

[Brent Thomann]

can anyone please let me know if I add a separate "LM3-RPM Remote Pump" to my LM3 will it too turn on and off because of the "LM3-TCM Top-off Control Module I have installed"

I am hoping there is a way I can add another remote pump and not have it shut off with the Top-off Control Module "LM3-TCM" want the second pump to control my CA Reactor and don't want it to shut on and off as my water evaporates.

Much Appreciated,
Brent

Brent,

You should not be relying exclusively on the TCM for top-off control. Doing so negates the precise dosing abilities of the LM3. Set the LM3 for a more accurate value of daily evaporation so it's not constantly turning the LM3 off. Now, if it hits a level high enough for the TCM to turn off, you probably have a bigger problem there than worrying about the CA reactor not running for a while.

will this work or would you suggest something else-

RO/DI Unit > Storage tank (with float valve and bladder tank inline) > Litermeter3 > Kalk Reactor > Sump (with LM3 TCM for safety overflow)

I would set the LM3 with the approx evaporation amount in one day. The LM3 TCM I guess would only activate if I dose to much, more than my evaporation rate disabling the LM3. Would it also disable a Remote Pump if I had it hooked up to LM3? Would again use the remote pump to run a separate CA Reactor that I wouldn't want shutting off at all or dose less than I program it to in 24 hrs.

To answer your first question, the TCM cuts the power to the LM3 and, of course, to any pumps plugged into it.

SpectraPure, Inc. cool got it.

Would it work if I set the TCM in sump at a desired height, setting LM3 above evaporation rate or even at its max. LM3 would turn on and off as water evaporates? wouldn't have to ever change any settings on LM3 this way cause my evaporation rate changes quite often with my fans, seasons, etc.

[SpectraPure]

It would work, but that's what we've been trying to avoid. When you rely on the TCM to top off, the water has to drop a whole INCH before it would turn back on. In a big sump, that could be a lot of water.

I'll bet your evap rate doesn't change so much so quickly from day-to-day and that you are never looking at your sump to help monitor a decent level anyway that you would have to rely on the TCM to keep properly topped-off.

I am having a problem trying to keep a some what consistent level in my sump? 3.6 gals evaporates a day out of my system and most of the evaporation takes place when my lights/fans are on.

Also, every time I calibrate my LM3 it gets a different flow rate from 160 to 175. Is this normal? I'm using it to pull RO/DI water 15 feet away from in my basement. Using a 500ml water bottle to calibrate.

Any suggestions?

The basic problem here is that you have signed on with the side of the argument that says you should only dose kalc at night. Many LM3 users successfully dose all day long and therefore do not have the evaporation get away from them.

The 15 feet is not a concern.

Where is the calibrated line on the water bottle? Is it accurate?

Try using a more narrow measuring bottle, or a graduated cylinder. The wider the bottle, the more inaccurate your measurement is.

Alternatively, do the calibration 10 times and take the average.

It's a narrower water bottle that I first used a measuring device to fill and mark correctly. Will do the 10 times average, good idea.

You think the LLC-UPLC ULTRA-PRECISE LIQUID LEVEL CONTROLLER would work better for me? be able to keep up with my evaporation better.

so dosing kalk the way I am 24/7 reduces evaporation? my PH never goes over 8. so thats why I am dosing kalk 24/7.

trying to get this right with very little maintenance has been very frustrating!

[SpectraPure]

Sorry, I misunderstood that you were only dosing the kalc (and top-off water) at night and by then the sump level was low. Didn't mean to suggest that dosing 24/7 reduces evaporation.

If there is nothing else basically wrong, I'd try dosing a stronger concentration of kalc, or look into the two-part methods.

The UPLC might be better for you, but I'd think the LM3 should do what you need doing.

lastly, when do you expect your remote pumps to be available again?

would like to get one to run my CA Reactor.

2 or 3 weeks.
