Our holding tank sensor/gauge does not work. The light on the gauge is on showing it is getting 12 volts, it is easy access to the sending unit, can these be cleaned or buy new?
Thanks Ray

Or you can do yourself a big favor and buy a SOLO sensor and panel (external or internal based upon your holding tank material). Uses the same wiring as the Tank Watch.
I couldn't agree more! Over the years (since 1995) I've tried all the holding tank monitors and Solo, is by far the best! No maintenance, no components inside the tank, truly a DIY project. (Super easy!) and a low price, compared to everything else that's on the market.Or you can do yourself a big favor and buy a SOLO sensor and panel (external or internal based upon your holding tank material).

Thanks for the replies, it is a Wema SHS which is standard equipment on the newer Mainships. It appears to be a tube with maybe a float inside? Have not taken it out of the tank yet, just looking at the web site. They have no information about cleaning or maintenance
WEMA gauges are standard on a lot of production boats 'cuz they're inexpensive. They're fine for water and fuel, but have always had a high failure rate in waste tanks because the the animal fats in waste, along with sea water minerals and urine crystals--the latter more common in tanks fed by toilets that use very little flush water--clog up the sender (same with the TankWatch and any other senders that are immersed in the contents). Removing 'em to clean 'em manually is the only way to clean 'em.
Btw, Chris...vinegar does work to clean scale off senders and inside hoses, but it's such a long and tedious process that requires changing the vinegar frequently (which you prob'ly didn't know to do) that it's not worth the effort. Much easier to use muriatic acid or Sew Clean and use distilled white vinegar to PREVENT buildup in hoses.

Given that it's 2016, I would strongly suggest against getting any tank level reporting product that doesn't have an NMEA 2000 or Signal K interface. It's sort of like getting a Loran in 1995. Get something that can warn you and interface to other capabilities - you'll be using it in 2020.
It doesn't appear like Profile, SCAD, SOLO, or whoever is making this and/or putting their name on it has any type of normal interface. At a minimum, ask them if it can be added. It should be part of the system and if enough people ask, maybe they'll add it.
Just my $0.02. Most people will likely disagree. Come back in 2020 and see if I was right...
I calibrated my "FULL" mark by filling up the tank with fresh water. I removed the cover that held the Tank Watch tubes and had a friend tell me when the water level was at the top of the tank. I then re attached the cover, did the "Full" calibration as per the instructions and everything worked fine! Just returned from a 140 mile cruise with 4 adults aboard, (4 days) and the tank monitor read ¾ full. (3 green lights) This is a great tank monitor!![]()
Have you contacted Maretron?Jeff,
Can you recommend a sensor that does work with NMEA2000? I have tried the Maretron TLM100 without much success in getting them to calibrate.
