Has anyone used the Tech-Edge iSeries Tank Monitor?

Has anyone used the Tech-Edge iSeries Tank Monitor? https://tankedge.com/products.html I have used a SeeLevel monitor and liked it, but after only a couple of years it is becoming erratic in it's readings, so I am considering switching to this brand. Anyone have experience with the iSeries?

This type of sensor is an externally mounted (on the tanks) capacitive sensor, which the top of the line RV's use. They are very accurate, and if you keep them out of the elements will give you excellent readings.

I installed a SeeLevel system on my trailer about five years ago. I had one problem with the monitor display, and found Garnet very responsive in solving the issue. If you have not contacted Garnet about your erratic readings it might be helpful to do so.

I sent them a message this morning. It's past the one year warranty so I'll see what they say.

Well they suggest checking the ground to see if it's corroded. I'll start with that. But again, has anyone used the Tech-Edge iSeries Tank Monitor?

What sort of erratic readings are you having? Is it that you push the button to get a read on a tank, and the display % varies up and down on the monitor? Or do you sometimes try to get a reading from one tank, and it is actually a reading from another tank? Or do the readings just seem wrong - you know the tank is almost empty, and you get a reading of, say, 50%?

If I remember correctly, when I installed our system the instructions specified that the ground for the sensors and the ground for the monitor had to be exactly the same; ie, connected by wire together and then to battery ground. Is that what they asked you to check?

By the way, it doesn't sound like their advice was very thorough or especially helpful.

Here is a list of the issues I am seeing, and what I wrote to Garnet:

"Hello, I have a your SeeLevel II RV tank monitor model 709-4 in my RV and it has functioned well for several years, however lately it's operation has become very erratic and inaccurate. The first problem I noticed is that when I filled my fresh water tank it showed only 17% full. Then we started a trip and the grey and galley tanks would show erratic numbers, jumping up and down with different button presses even though the tanks levels were rising. Ironically the black tank sensor seems to still be accurate, but the freshwater tank sensor shows either 0%, 17%, or 25%, even though the actual level has remained at 75%. If I press the grey and then galley buttons, instead of changing numbers, its triggers the hold mode. These problems occur regardless of whether or not it is connected to AC power. I ran diagnostics and it shows no problems. Fresh tank shows P78 and H3. All other tanks show P67 and H3. Do you have any advice on how to correct these issues?"

And their response:

"The first thing I would check is the ground that is being used. Just make sure that ground is still a good ground and the connections to ground are good. If that’s the problem, then fixing the ground should fix your problems."

Checking the ground makes sense. By the way, I checked my install directions and there is some stress on the importance of the display and all the sensors being connected to the same ground.

This makes me wonder if the display itself is flaky, because as you know pressing and holding an individual tank check button is supposed to trigger hold on the display of that tank, not a sequence of pressing different buttons.

In case you don't have it, Garnet's contact phone number is 817-587-8601. I had to call them when my display got flaky to explain the problem. I forget which buttons were flaky, but for example when pressing the Grey tank button the Galley tank level would display.

Yes. Mine was just a bad display - the guy at Garnet said that "a reed had dropped" - something to do with the switches mechanically not working properly. All I had to do was to take it loose from the wall, unplug the connectors, and put the connectors back on the new one and re-install it onto the wall. It may have required me to re-program the display, but that is in the instruction book and is no big deal.
