Buying Guide

Match connection size and type

Choose a meter with the correct thread or inline mounting (1/2" NPT, DN15, DN20, or inline 1/2"/3/4") to avoid adapters that can introduce leaks or pressure loss

Prefer brass or durable housings

Brass bodies resist corrosion and physical wear better than plastic in plumbing applications, extending service life for residential and light commercial use

Know readout and output needs

Select between direct gallon/volume readouts for manual checks or meters with pulse outputs if you plan to integrate with data loggers or counters

Consider flow range and accuracy

Verify the meter's usable flow range matches your application—too-large meters lose resolution at low flow, while undersized meters can create pressure drop

Check installation orientation and mounting

Confirm required orientation (inline or specific flow direction) and available clearance; inline-mount designs and 1/2" or 3/4" fittings affect where the meter can be placed
