Alternative for Adafruit flowmeters

Hello all,

i’m looking into buying 3 flowmeters. I’m from Europe and shipping costs from the US are a bit high. So i am looking for an alternative for the Adafruit flowmeters. What are the specs of a usable meter?

Thanks in advance,

I went through quite few in my testing before settling on YF-S401:
