DAE water meter 1/2" measuring in gallon + couplings vs Watflow DN20 water meter 3/4" NPT with pulse output

Overall winner: DAE water meter 1/2" measuring in gallon + couplings

Key Differences

DAE AS130U-50 (A) is a 1/2" inline-mount meter praised for accurate gallon measurement, easy-to-read digits, and simple installation but has mounting-orientation limits noted in guidance. Watflow 3/4" NPT (B) uses a brass, corrosion-resistant body and adds a pulse output for monitoring and NPT compatibility, but lacks a lead-free option and may have reduced low-flow accuracy (~3%)
