Flow Meter Help

[SmellsLikeSyrupNH]

Hi everyone,
I purchased 3 flow meters for my RO. Im having a hard time finding 20mm 1/2BSP barbed fittings for the back of the meters to connect my hoses. If anyone has purchased or used these Flow Meters from Amazon, could you let me know what you did?

Thanks!

I bought some on ebay last year for this.
