Adding simple flowmeter or not?

[kilnakorr]

I have this simple flowmeter, which I could add to the returnline.
The only place to add it would be the back of the tank (I have return on the back).
It shows 300-3000l/h, so close to 1-10x turnover.
Should I add it or not bother?

The main thing I would look for is that most flow meters of this style are not saltwater safe and will rust over time. If you know the meter is safe for seawater then I would go for it.

Yes, if parts are plastic, reef safe it is good to know real flow.

Seems the center pin is made from some sort of metal.
Not sure I want to risk it.

It should have a list of suitable liquids, could Google the part number.
