The flowmeter is light and handy, easy to install. The sealing ring make the connection firm, the sealing performance is good and the problem of water leakage is avoided. More details about the flow meter: F=(23*Q)±2%, Q=L/Min, error: ±2% Working range: 0.3-6L/min Working voltage: DC 5-24 V Water Pressure: ≤0.8Mpa Liquid temperature: 0-100℃ Maximum current: 15 mA(DC 5V) Wire length: 15 cm Size: 58mm x 34mm x 27mm(L*W*H) Refer to the wiring: Red wire: VCC(+) Black wire: GND(-) Yellow wire: Signal output Package: 2 x G1/4 inch flowmeter male thread Review: All looks good - I have tried these with my watercooling kit and they seem to play along just fine with the fittings. They seem compatible (after re-wiring the plug) with computer fans (electrically at least). Output (in Hz) appears to be "Liters/minute=Hz/200" (i.e. if you measure 1,4KHz it means that you have 7Lt/min flow) as measured with my oscilloscope and cheap flow meter. Review: leaks like a sieve - Received 1 piece in package marked (pack of 2), attempted to use device but it severely leaked through the rubber gasket. Would not recommend any purchase of this device. ## Features - Connect to G1/4 inch male thread, hall effect, comes with 2 pieces - Flow range:0.3-6L/min, Water Pressure: ≤0.8Mpa - Working voltage: DC 5-24 V, F=(23*Q) ±2%, Q=L/Min - Material: food grade plastic, all raw materials conform to the ROHS test standard - Wide application: It is mainly used in water heater, coffee machine, water purifier, drinking fountain, beverage machine, campus smart card equipment, etc. ## Technical Specifications | Specification | Value | |---------------|-------| | Customer Reviews | 3.6 out of 5 stars 6 Reviews | ## Images ![1/4" Water Flow Sensor Food-Grade Switch Hall Effect Flowmeter Fluid Meter Counter 0.3-6L/min (Pack of 2） - Image 1](https://m.media-amazon.com/images/I/61vhBFlxZTL.jpg) ![1/4" Water Flow Sensor Food-Grade Switch Hall Effect Flowmeter Fluid Meter Counter 0.3-6L/min (Pack of 2） - Image 2](https://m.media-amazon.com/images/I/61QY3rf3ROL.jpg) ![1/4" Water Flow Sensor Food-Grade Switch Hall Effect Flowmeter Fluid Meter Counter 0.3-6L/min (Pack of 2） - Image 3](https://m.media-amazon.com/images/I/618J7MIobNL.jpg) ![1/4" Water Flow Sensor Food-Grade Switch Hall Effect Flowmeter Fluid Meter Counter 0.3-6L/min (Pack of 2） - Image 4](https://m.media-amazon.com/images/I/51OoMmeu1fL.jpg) ![1/4" Water Flow Sensor Food-Grade Switch Hall Effect Flowmeter Fluid Meter Counter 0.3-6L/min (Pack of 2） - Image 5](https://m.media-amazon.com/images/I/51+Y0DPEzwL.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ All looks good *by K***S on November 24, 2024* I have tried these with my watercooling kit and they seem to play along just fine with the fittings. They seem compatible (after re-wiring the plug) with computer fans (electrically at least). Output (in Hz) appears to be "Liters/minute=Hz/200" (i.e. if you measure 1,4KHz it means that you have 7Lt/min flow) as measured with my oscilloscope and cheap flow meter. ### ⭐ leaks like a sieve *by A***N on June 20, 2022* Received 1 piece in package marked (pack of 2), attempted to use device but it severely leaked through the rubber gasket. Would not recommend any purchase of this device. ### ⭐⭐⭐⭐ Sourcing PLC Input to Read Pulses *by S***T on December 4, 2021* I ordered this to test measuring low flows from chemical dosing pumps. The sensor must be an NPN (sinking) transistor, as it would only work when wired to a sourcing PLC input on my Micro 850 PLC. --- ## 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.ae/products/160091751-1-4-water-flow-sensor-food-grade-switch-hall-effect](https://www.desertcart.ae/products/160091751-1-4-water-flow-sensor-food-grade-switch-hall-effect) --- *Product available on Desertcart United Arab Emirates* *Store origin: AE* *Last updated: 2026-05-12*
