P3 Water Flow Meter 2-Pack - Brass Swivel, Accurate to 0.1 Gallon

In this review of the P3 Water Flow Meter 2-Pack, the bottom line is simple: gardeners, campers, and anyone tracking outdoor water use will appreciate an inexpensive, accurate way to measure gallons from a hose. The meters install between faucet and hose and deliver an easy to read LCD that reports single-use and cumulative volumes, removing guesswork when filling reservoirs, running sprinklers, or monitoring water for drought-conscious watering. For those who want straightforward measurement and a brass swivel that resists seizing, this pair is a practical choice.

Key Features

• Brass hose swivel: Provides a durable threaded connection that resists corrosion and makes attaching or removing the hose simpler over time.
• Accurate to 1/10 of a gallon: Delivers precise volume readings suitable for measuring reservoir fills, individual plant irrigation, or short timed watering runs.
• Simple to attach: Installs between faucet and hose with standard fittings so most users can fit it without tools or plumbing changes.
• Calculates single and total use: Tracks both the water used in a single watering session and the running total, helping manage consumption over a season.
• Easy to read LCD: The display is clear outdoors so users can check flow while watering or after a session to log usage.
• Two-pack convenience: Having two meters lets a user monitor two hoses or keep a spare for camping or remote tasks.

Who It's For

This meter is for homeowners with lawns, gardeners with beds or greenhouses, and campers who need to track exact gallon usage for reservoirs or portable showers. It suits anyone who wants to remove guesswork from watering schedules and measure consumption for conservation or billing purposes.

It is less suited to those needing industrial duty or continuous commercial irrigation monitoring; customers looking for long-term heavy commercial duty should consider ruggedized flow systems because some buyers reported durability concerns after months of use.

Pros & Cons

Pros

• Accurate readings to one tenth of a gallon make measurement reliable for garden and camping tasks.
• Brass swivel gives a stable, corrosion-resistant connection that eases installation and use.
• Tracks both single watering and accumulative totals so users can monitor usage over time.
• Two meters in the pack increase flexibility for multiple hoses or backups.

Cons

• Some users have reported durability issues with the unit breaking within a few months, so it may not be ideal for very heavy daily use.
• The LCD and plastic housing may be less robust than commercial-grade alternatives for long continuous outdoor exposure.
