Designed with food-grade, ROHS-compliant materials, it supports DC 5-24V operation and up to 0.8Mpa water pressure. Its compact, leak-proof quick connector makes it perfect for professional-grade water heaters, coffee machines, and smart beverage systems. ## Description Our products are fine made with nice materials and good workmanship, strict quality control, guarantee in after service. 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=(38*Q)±3%, Q=L/Min, error: ±3% Working range: 0.3-6L/min Working voltage: DC 5-24 V Water Pressure: ≤0.8Mpa Liquid temperature: 0-100℃ Maximum current consumption: 15 mA(DC 5V) Wire length: 15 cm Size: 54mm x 35mm x 28mm(L*W*H) Refer to the wiring: Red wire: VCC(+) Black wire: GND(-) Yellow wire: Signal output Package: 1 x G1/4 inch flowmeter quick connect Review: For may application they work better with a small modification - They work well and have been reliable and repeatable so far. I am using them on a keg level monitoring system. I found I can drill-out the input side (take apart the sensor first!) with a 1/8" drill bit and get less breakout (less foam) with minimal impact on the repeatability of pours. The K-factor drops from about 4600 to 2800 but that is still plenty of resolution for this system. Review: Item Measures Volume Accurately - This works great interfacing worh Arduino. The price can be lowered a bit for the size of the product and considering it's foreign made. Interfacing with Arduino and writing the correct program gave me very good accuracy in the volumetric displacement measurements that I was taking for a RO water system efficiency test. ## Features - Connect to a G1/4 inch tube, quick connector, hall effect - Flow range:0.3-6L/min, Water Pressure: ≤0.8Mpa - Working voltage: DC 5-24 V, F=(38*Q)±3%, 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 | 4.1 out of 5 stars 27 Reviews | ## Images ![1/4" Quick Connect Water Flow Sensor Food-Grade Switch Hall Effect Flowmeter Fluid Meter Counter 0.3-6L/min - Image 1](https://m.media-amazon.com/images/I/61z8BC1L+OL.jpg) ![1/4" Quick Connect Water Flow Sensor Food-Grade Switch Hall Effect Flowmeter Fluid Meter Counter 0.3-6L/min - Image 2](https://m.media-amazon.com/images/I/61WwHEMEFgL.jpg) ![1/4" Quick Connect Water Flow Sensor Food-Grade Switch Hall Effect Flowmeter Fluid Meter Counter 0.3-6L/min - Image 3](https://m.media-amazon.com/images/I/611f2xq8pQL.jpg) ![1/4" Quick Connect Water Flow Sensor Food-Grade Switch Hall Effect Flowmeter Fluid Meter Counter 0.3-6L/min - Image 4](https://m.media-amazon.com/images/I/51kGpqhyKCL.jpg) ![1/4" Quick Connect Water Flow Sensor Food-Grade Switch Hall Effect Flowmeter Fluid Meter Counter 0.3-6L/min - Image 5](https://m.media-amazon.com/images/I/71ShB2WyLhL.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ For may application they work better with a small modification *by B***I on March 30, 2026* They work well and have been reliable and repeatable so far.
