Neptune Flow Meter

If you mean rust, no, I do not.
Here is a fairly recent pic of them and they are still in pretty good condition.

Wow now that's pett

Back to the OP actual question .....

Flow sensors work fine as long as you set them up to minimize clogging and accept that a periodic disassembly for cleaning will be required. Also, be careful about what a zero reading will trigger.

I have had a bunch of them on my system, pretty much since the first day they were available. Never had any issues with the 2" version, and only once with the 1/2". It's the 1" that, for me, is prone to clogging (usually strings of chaeto). Sometimes back flushing does the trick, but usually it requires disassembly and cleaning.

That's not good news. I just started a refugium in my sump with Chaeto and Ulva. I have had little to no issues with my 1" Neptune Flow Meters for almost a year. I will have to keep an eye on them now that I have Chaeto.

OP, possibly you can tie your UV Sterilizer program to the flow meter and pump power draw (what #Pistondog suggested) though I'm not sure what the program would look like. That way you would have redundant fail-safes. Or, that might be getting more complicated then it needs to be.

I was looking into adding a flow meter to my uv sterilizer so I can monitor the flow, but also configure slerts and turn the pump an sterilizer off if gph hits <10gph. are they really as bad as the reviews on vendors sites state? I couldn't find much here except for a post or two and for sale threads.

Fallback OFF
Set ON
If Output Uv_carbon_pu = OFF Then OFF
If Power Apex Off 002 Then OFF
if UV_FLO <50 Then off
I think this what your looking for

Yea, I assume that will require a virtual outlet, but excellent suggestion. Thank you! I am still torn about the flow meter and may revisit it at a later date.

In the uv lamp advanced logic, the following will turn it off if the uv pump is not drawing at least 5 watts.

If output uv_pump watts < 5 then off

Well I can tell you this I have used one for about a year. Then six months ago I add 6 more. I love them! They saved my pump two times now

There are a number of ways you can protect the UV. I have a flow meter on my main pump. if the flow drops to zero or the pump outlet is off, the UV turns off. I also have a high level float switch in the sump. If that engages, I assume the main pump is off, and the UV turns off.
