Neptune flow meter for wort

[itivino]

Anyone using a netpune flow meter between their MT and BK (or HLT to MLT) ? Looking at them on ebay for around $20-$25, temperature rating seems to be 149 though based on 1 spec sheet I could find. Wondering if I can get away with it ? Primarily for measuring sparge flow rate and volumes.

Here is another with a 250F temperature rating, $60 (though no totalizer):

Do you know what it's made out of? I'm assuming it might be ok if it's made of brass. I've been looking for something like that too, but I always change my mind, and decide I am overthinking it.

Fairly certain it's made of brass, though can't find in the documentation what the internals are made of.

This one here may be another choice, looks like it's aluminum:

The description says it only reads high flow. 10l or more a minute.
