At about 3 l / min, the one have reads about 30% over the correct value but it seems fairly consistent and easily compensated for. Review: Flussometro - Se si usa come relè on/off va benissimo, ma se vi serve misurare effettivamente il flusso non è molto preciso. ## Features - Easy to install, 1/4 Quick connect. - Flow range:0.3-10L/min. - Frequency: F=38 * Q (L / Min) error: ± 2% - Working voltage range: 3.5-12 VDC. - Pressure range: 0-0.8MPa. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01D44N41U | | Brand | DIGITEN | | Brand Name | DIGITEN | | Color | White | | Colour | White | | Connector Type | Quick-connect | | Connector type | Quick-connect | | Customer Reviews | 4.2 out of 5 stars 65 Reviews | | Exterior Finish | Brass | | Item Dimensions | 6.4 x 3 x 3.8 centimeters | | Item Weight | 30 Grams | | Item dimensions L x W x H | 6.4 x 3 x 3.8 centimeters | | Manufacturer | DIGITEN | | Manufacturer Part Number | FL-S402B | | Material | Plastic | | Material Type | Plastic | | Model Number | BuildingMaterials | | Number of Pieces | 1 | | Thread Size | 0.25 inches | | Thread Type | UN | | Thread size | 0.25 inches | | Unit Count | 1.0 Count | ## Product Details - **Brand:** DIGITEN - **Colour:** White - **Connector type:** Quick-connect - **Item dimensions L x W x H:** 6.4 x 3 x 3.8 centimeters - **Material:** Plastic ## Images ![DIGITEN G1/4" Quick Connect 0.3-10L/min Water Hall Effect Flow Sensor Meter - Image 1](https://m.media-amazon.com/images/I/71c4Pl1t+HL.jpg) ## Questions & Answers **Q: Is this food grade - can I use it to measure beer transfer rate?** A: Yes, it is food grade. thank you! **Q: What type of electrical connector is that? What would I need to connect to it?** A: this connector is a male 2.54mm JST-XHP 3 Pin I tested this flowmeters male connector when it arrived and it matched perfectly with the female 2.54mm JST-XHP 3 Pin connector. The other answer said it might be a JST-PH. This is WRONG! I also bought those and they did not work. I purchased the following kit and the 3-pin female connector worked. https://www.amazon.com/gp/product/B01IHFYT1U/ref=oh_aui_detailpage_o02_s00?ie=UTF8&psc=1 **Q: Can these be used for air flow, we need in 24 vdc, 1/4" npt** A: Probably not..reliably. however I blew into it with a small length of 1/4 tube to test it and the rotor turned just fine.and I could measure the output pulses. **Q: Digiten, why do none of your products ship to apo? its no different than a regular address.** A: Order it off of ebay. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works as expected *by C***S on 12 October 2019* I am running them at 3.3V and they seem to work fine with that. At about 3 l / min, the one have reads about 30% over the correct value but it seems fairly consistent and easily compensated for. ### ⭐⭐⭐⭐⭐ Flussometro *by C***N on 19 December 2018* Se si usa come relè on/off va benissimo, ma se vi serve misurare effettivamente il flusso non è molto preciso. ### ⭐⭐⭐⭐⭐ Basic low cost meter works well *by A***X on 12 February 2022* I got this to keep track of water usage on my RO system so I would know when to replace the filters. This meter works as expected but I wouldn’t trust the calibration. Anyone setting this up should calibrate it on their own. I marked a line on a jug that was exactly 1 gallon and took the average of filling 5 gallons. I found that on average I got about 8120 pulses per gallon. Knowing this I can now keep track of total volume and flow rate. Keep in mind that low flow will not measure the same as high flow. This is fairly common in turbine style meters so calibrate your pulses per gallon at about the same flow rate you expect to use it. I just installed this today so I can’t speak to its longevity but so far no leaks with 55 PSI on the meter at all times. Overall I would say it’s a good meter as long as high accuracy isn’t your goal but for the price of this meter I’d say it’s worth it. ## Frequently Bought Together - DIGITEN 1/4 Quick Connect 0.3-10L/min Water Hall Effect Flow Sensor Meter - DIGITEN DC 12V 1/4" Inlet Feed Water Solenoid Valve Quick Connect N/C normally Closed - GREDIA 1/4" Quick Connect Water Flow Sensor Food-Grade Switch Hall Effect Flowmeter Fluid Meter Counter 0.3-6L/min (Pack of 2） --- ## 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.us/products/259062315-digiten-g1-4-quick-connect-0-3-10l-min-water](https://www.desertcart.us/products/259062315-digiten-g1-4-quick-connect-0-3-10l-min-water) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-07-21*
