Don’t go for second best.
Knowing Dwyer quality for almost 40 years, that was the first option when I decided to buy 4 flow meters to repair some nebulizers.

My flowmeter was leaking at the valve on arrival
If you receive a defective flow meter like I did (leaking at the valve), there is a solution to fix it. I unscrewed the valve as far as I could and wrapped the threads with Teflon tape. When I put it back on line, it no longer leaked.
