Salinity probe in a vertical 150 gallon mixing tank
Hoping someone has an idea I can steal! I want to put my apex salinity probe in my salt mixing tank near the bottom, so no matter the level it is submerged. Easy enough I thought, I can just use a strain relief through the tank like a ph probe in a calcium reactor. Then I got to thinking about having to calibrate it and what a PITA that would be if it were near the bottom and the tank was full. So, before I put a bulkhead in the top of my tank and put a PVC section down with a strain relief at the end to hold the probe (apex probe so I need to keep the wire end of it dry) which will not be easy to deal with because the ceiling in the basement is only about a foot above the top of the tank so I can't pull 4 feet of pipe strait out, I'm seeing what ideas the community may have.
Thanks in advance! Matt

Salinity probe in a vertical 150 gallon mixing tank
Uniseal through side at bottom, with 3/4 pvc pipe (couple inches) and a valve to a 90 pointing up. Put a cap in the 90 with a small uniseal that the probe will fit in (might need to work on this bit). Kinda like the small T fittings your rodi tds sensor fits in.
Edit- thinking about it some more, you’ll probably bust the probe trying to get it in and out of the uniseal. Should have thought it through some more before I made a suggestion. Sent from my iPhone using Tapatalk Last edited by neilp2006; 12/30/2017 at 06:00 PM. |

What is the ‘strain relief fitting’ you refer too? I might find it useful for my own system

Can the probe be oriented horizontally? Not sure, but if so you could just stick it through the probe holder in the side. The other option would be to plumb an external circulating mixing pump and have the probe in the pump circuit.

Mount the probe onto a piece of foam so that it floats on the top of the water column. When you need to calibrate, just pull it up out the top of the tank.

Don't strictly rely on the correct readings. Use the probe reading to get you close, but you still gotta check with your refractometer. Just my opinion.

What are you going to do about the temp probe? If your going to monitor the salinity using a the Apex, you will need a temp probe in there for proper temp compensation if you want reasonable accuracy.
