Buying Guide

Match connection size and thread

Confirm your system uses DN15 / 1/2" NPT fittings so the meter threads and sealing method match without adapters

Prefer brass or corrosion-resistant bodies

A brass-body meter resists corrosion in outdoor and variable-water conditions, improving longevity for irrigation use

Check for pulse or electronic output

Pulse-output meters integrate with flow controllers and data loggers for automated monitoring and water budgeting

Consider accuracy and repeatability

Look for models with reliable calibration and user reviews noting consistent readings across typical irrigation flow rates

Balance cost and durability

Budget options under $50 can work for basic setups, but weigh construction quality and features like pulse output when evaluating value
