tank level monitoring system SEE level ll

Hmmm, sounds like conformal coating on these sensor strips might be in order to help avoid problems.

A potentially confusing array of such can be found on Amazon, helpful info on different coating types can be found here.

My personal favorite is this one, a little goes a long way.

MaxxFan circuit boards are another that can be susceptible to moisture issues.

Thanks for the recommendation!

Hi Alan

I need to use some conformal coating on my Maxx fan circuit board. The 419D type you link to is not readily available on Amazon.ca but the 422C type is. The descriptions of the two sound very similar. In your opinion, would they be interchangeable?

Probably just fine, that's a silicone-type (vs acrylic for 419D), read about the differences on the info link in my previous post.

I've never used the silicone-type, I just like the acrylic because it seems to have all the protective characteristics I need and is about half the price of the silicone in the US.

I've used CRC seal coat for my MaxxFan circuit boards (I have two MaxxFans) and so far so good. The spray can makes it easy to apply just make sure you mask off electrical contacts and open female electrical connectors before spraying. Not sure if It's available at Amazon.ca

Thanks Alan. Now I'll have to brush up (haha) on application technique.

SeeLevel sensor protection

.... The sender was WET and of course the components on the sender’s circuit board were ruined. ...

Hmmm, sounds like conformal coating on these sensor strips might be in order to help avoid problems. ...

Following up to share info clipped verbatim from the SeeLevel FAQ page (Amazon product links added by me):

Is the sender panel waterproof?
No. The sender panels are sprayed with a protective coating for some protection.

Can you cover the sensors with anything to keep road spray off of them?
On installations where the holding tank is exposed to under-chassis road spray and flying rocks etc., we recommend the use of rubberized undercoating.

Recommended brands:
3M 03584 Professional Grade Rubberized Undercoating
Gravel Guard Rocker Guard Coating By Dominion Sure Seal
Gorilla Glue Waterproof Patch & Seal Tape
​

It might be that one of the recommended spray-on undercoatings would provide best moisture protection. Perhaps the intimate contact with the irregular surface of the sensor strips and adjacent tank (e.g. an area beyond the edges of the sensor) would offer better long-term performance in the face of both direct-splash and condensation than tape and be much more robust than any conformal coating alone.

Just FYI / for your consideration.

Personally, I like the SeeLevel system, it seems to be much less sensitive to 'probe contamination issues' than those using probes in contact with the tank contents. YMMV.

My SeeLevel tank monitoring system started acting up after I had my axles replaced. My guess is some wires got knocked loose during the process. Crawling under the trailer this evening to check it out.
