RESTMO Water Flow Meter. Know Exactly How Much Water You're Putting In.

September 19, 2026

RV fresh water tank gauges are wrong more often than they are right. The only way to know exactly how much water went into your tank is to measure it as it goes in. This RESTMO flow meter connects inline on your garden hose and counts every gallon. Brass inlet, metal thread, reads in gallons or liters. Done.

What It Does

Why This Matters for Full-Time RVers

If you fill your fresh water tank regularly, your onboard gauge will lie to you. Most RV tank sensors read inaccurately within the first year. A flow meter gives you the actual gallon count as it goes in. You know your tank capacity. You fill to that number. No guessing, no overflow, no wasted time standing at the spigot wondering.
