I am pretty sure that he primed the lines. The beauty of the Liter Meter is that you could have 1 pump do 200 ml/pm, and another do 100 ml/pm, and the liter meter will exchange the same exact volume.

You program the LiterMeter to however many liters per day that you want to exchange per day. If you want to do 3 gallons per day, but only want to make water once a week. 3*7=21. So make sure that you make 21+ gallons. I make 25 gallons a week, and mine is set to 3 gallons a day.

I am still a little confused. I understand the water exchange. What I am wondering is if I forget to make water, or I'm not home for some reason, will the system know there is no water and stop the process?

No it does not do that. There has to be water. The Liter Meter only takes water that is made and transfers it. We do recommend that you only put the drain tube from the sump only 2 inches below the water surface. If you run out of water, then the sump can only be drained 2 inches rather than all the way.

That right there is a major flaw in IMHO. I've accomplished this low saltwater safty with a $2 float switch and a relay. I would not run such a system without this feature whether built into the device or separate via a power cutoff relay or your apex etc.
Despite how diligent we are at some point life will happen and we will forget to make water, and at the same time the dog/cat/child of the house will bump the drainline pushing it deeper into your sump (which doesn't really matter since if you have an ATO you will continue to drain ever more diluted saltwater and only replace it with fresh water, so really the only thing that having the drain intake 2" below water is preventing is a siphon from draining the tank should your line break.........)
anyway, I guess I had thought that the pump system that eddie was getting to test was a new product design..........

You are certainly free to use that float switch, relay, APEX, Octopus, etc. for some of the situations you describe. The LM3 can have power removed by any kind of control system you have and it will remember where to pick up again when power is restored.
If a line breaks, gets bumped, or plugs up with kalc, a float switch in the reservoir won't help.

As long as it will keep the memory the float switch will be an easy fix for this.

But correct me if I am wrong here Jeremy I have the top off unit from spectrapure for the rodi also running on my system and with the rodi unit set up like this you can not just forget to make water as it does it for you .....there is no just forget ...it also keeps my rodi unit pressurized to avoid tds creep

Which Top-off module do you have? Also this is for water exchange. Yes water will automatically fill and top-off just fine, but you need a way for the system to auto mix salt into a separate reservoir. If you can automate your salt mix, then the Liter Meter will continue to do its job.
The Liter Meter 3 can integrate with the Apex by killing the circuit that it is being used on as Scott stated.

Yes I did. buit there was not much to prime since all i did was unplug the lines from the Stenner and hooked then up to the LM3, only a few bubbles where noted probable from when I disconnested, but i did prime it anyways.

Nope no need to mix I use NSW.....have 1500gals on hand outside and 300gal inside .... the top off he was talking about not shutting off or turning on I was under impression was his RODI storage going into the tank and yes thats just a simple float switch.......not his mix satiation but thats simple also with a few simple float switches and an automatic shut off for the RODI and an alarm email from your apex to notify you to dump in proper amount of salt at a given time after the float switches shut off the awc and then turn on automatically a circulation pump then return on the awc after a specified time and notification from the float switches ....
only thing I need to be concerned about is that my 300 stays filled and I am working on that staying filled automatically from the 1500....once thats done its set and forget for automatic large water changes if I choose and also continuous daily water changes for a month or more....when its in bulk or free water is cheaper than electricity and maybe one day we will be able to at somepoint just do away with large skimmer pumps, chillers kicking on less from heat of said pumps and any type of mechanical filtration pumps with just enough water being changed out per month.....we will see, it would be nice to lower the electric bill from just changing out water :beer:

One, then the other.....150 times per day.
Won't the ATO kick on and dilute the water?
I would think that 150 iterations it would be low enough to not trigger the ATO BUT if it were, the fill up pump would just add the same amount in regardless adding more saltwater and causing the ato to kick in later thus evaporation bringing it back to the same point..but how do you know that its removing and then adding? It potentially could add water then remove the excess...just saying. Either way as long as the LM3 is add/removing same amount the salinity won't budge regardless of ATO usage.

A good ATO has duty cycles. Thus, the cycle can be set lower to plan for salinity shift. You can ADD, then Remove, but most ATO on the market have a 2 inch gap. The Liter Meter would never remove 2 inches of sump water. Adding first and removing second is wasting a small portion of good saltwater, but in the end it is all the same.
