Wiring is a little short for most applications where you need to route the cable. But worked. ### ⭐⭐⭐⭐⭐ works well *by on Reviewed in the United States 14 December 2020* calibrationFactor = 6.9745; // millilitre calibrated over 2 litres ### ⭐⭐⭐⭐ Not for beer *by on Reviewed in the United States 11 September 2025* It's really 5 stars. This flowmeter works with water, or I suppose with any other fluid it's rated for. The function is 100%. I got this for my kegerator, hoping to measure the amount of beer used from my keg. The issue I had is that this flow meter, is it agitates the beer, so only foam is coming out. Not the fault of the sensor per se, the sensor it self works perfectly. It does not work well with beer though, a heads up for anyone wanting to try it for that application. ## Frequently Bought Together - DIGITEN G1/4" Water Flow Sensor, Food-Grade Hall Effect Sensor Flow Meter Flowmeter Counter Connect Hose 0.3-6L/min - Arduino, Raspberry Pi, and Reverse Osmosis Filter Compatible - uxcell 1/4" Hall Effect Water Flow Sensor Switch Flowmeter Counter Fluid Meter DC5V 0.15-1.5L/min SEN-HW06K --- ## 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.in/products/249095163-senstreeg1-4-water-flow-sensor-food-grade-hall-effect-sensor](https://www.desertcart.in/products/249095163-senstreeg1-4-water-flow-sensor-food-grade-hall-effect-sensor) --- *Product available on Desertcart India* *Store origin: IN* *Last updated: 2026-08-27*
