Inline Probes - Flow Rate

[Bill Amaro]

I am interested in installing my Neptune Temp and PH probe inline instead of just sticking them in one of the sump chambers with a probe holder. Mostly to keep the connector ends out of the water when the level in the sump rises.

Does anyone know if there is a min/max/suggested flow rate for probes that are installed inline.

Can't seem to find anything online, but my thoughts are as follows:

1) Lower flow is better than higher flow to prevent damage to the probes.

2) Min flow rate rate would be 10GPH thru the holder device.

Comments/Thoughts are greatly appreciated...

Since no one has answered this I'll take a stab. I would guess they will be fine inline even with significant flow rates. I have clients who use the same probes in the water supply lines in turkey barns with MASSIVE flow rates. Be careful with the seal on them as they have a tendency to leak.

Thanks nezw0001... Doesn't appear to be too much out there on this topic.

This is a new tank build, so I have 3 options for placement:

1) Return to my DT.. I expect that to have somewhere between 400 to 700 GPH
2) Standalone manifold pump - Media reactor Feed Line - between 10 to 15 GPH
3) Same pump as in option 2 - Algae Turf Scrubber Feed Line - between 180 and 210 GPH

My original though was option 2, but based on your observation and one other thread I found, I think I will install on my Algae Turf Scrubber Feed Line (option 3). I will make sure to plumb it so that I can turn off the ATS, but have water still flow thru the Feed Line and directly back into the sump since I know I need to do weekly or bi-weekly maintenance on the ATS.

Thanks again for your observation.
