Not concerned about leaks at all. ### ⭐⭐⭐⭐ The accuracy is spot on. Low resolution could be an issue for more cirtical r3eequirements. *by B***Y on 26 August 2025* After using to monitor water flow I found the accuracy to be very good however, do not expect much from the resolution as the granularity can be a bit low for critical flow rates. Given the low cost that is to be expected. ## Frequently Bought Together - GREDIA G1-1/2" 1.5" Water Flow Sensor Food-Grade Switch Hall Effect Flowmeter Fluid Meter Counter 5-150L/min - Ximimark 2Pcs 1/2" Thread Plastic Electric Solenoid Valve Water Inlet Flow Switch Magnetic Water Air Normally Closed Tools DC 12V N/C 0.02 to 0.8mpa - GREDIA 3/4" DC 12V Solenoid Valve N/C Normally Closed Water Inlet Flow Switch --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.fr/products/391724572-g1-1-2-1-5-water-flow-sensor-food-grade](https://www.desertcart.fr/products/391724572-g1-1-2-1-5-water-flow-sensor-food-grade) --- *Product available on Desertcart France* *Store origin: FR* *Last updated: 2026-08-29*
