It supports a wide voltage range (0-220V AC/DC) and features an integrated sediment filter to protect internal components. Built for durability and reliability, it’s ideal for water heaters, pumps, boilers, and various industrial water systems, ensuring automatic shutoff when no flow is detected to prevent damage. ## Description Main application:Magnetic Water Flow Switch adopts a Magnetic Reed Switch and a movable magnet which is fixed inside the water pipe. When water runs through the pipe part, the magnet will detect the water flow, and the magnet is shoved to one side by the flow. This then attracts the conductive strip which gets pulled down and makes contact, which completes the circuit and activates whatever electrical device you have attached to itSpecifications:Thread type: 1/2" BSP Male ThreadOperation voltage: 0-220V(AC or DC)Flow range: 1-30L/minWorking temperature: 1-120℃Mini start water pressure: 0.02MpaMax working pressure: 1.75 MPaMax loading power: 50WWorking current: 0-2AResponse time: 0.2SMaterial: BrassMale Thread External Diameter: 20.55mm(0.8 inches)Tube Length: 60mm(2.36 inch)Cable Length: 29cm(11.41 inch)Size: 60mm*30mm*30mm(L*W*H)Please Note:Don't forget to mark which way the old flow switch arrow is pointing so you can install exactly the same.When connecting the load, please add a relay.Package Include:Brass Flow Switch x 1 Review: work great. - works fine to turn on my relay, to power my hot water heater elements. Review: Important Instructions on Use - Don't make the mistake of connecting a magnetic reed switch directly in line with power as that will either damage it immediately or it just won't last. Instead, connect it to the “trigger wires” of a relay. The following configuration works: 1. Purchase a delay relay that has a Continuous Trigger Signal mode. Example: XY-WJ01 Programmable Relay https://www.desertcart.com/gp/product/B081N5NG8Q/ (Mode 8) 2. Connect the DIGITEN switch wires to the red and black Trigger wires 3. Connect power to the relay, set it to Mode 8 (don’t set any times) and connect the load When the DIGITEN switch closes, which holds the Trigger wires closed, the relay operation will start and continue until the Trigger wires are open again. The micro voltage of the trigger signaling places less stress on the reed switch and it should last a long time. ## Features - 🌟🌊【Safe and Reliable】This flow sensor switch is made of brass, all materials are in line with ROHS testing standards. It's a safety device that shuts off the current to the device (heaters, pumps, etc.) when it senses no water flow. When connecting the load, please add a relay. - 🌟💧 【Specail Design】This flow sensor has equipped with filter water entry. It have a filter to prevent sediments from getting in the workings of the sensor. Thread type: 1/2" BSP Male Thread. Male Thread External Diameter: 20.55mm. - 🌟🌊【 Easy to install】Our flow sensor has great quality and it is waterproof, heat resistance, pressurresistance, cold resistance, small size, stable and reliable. - 🌟💧 【Specification】This flow sensor`s operation voltage: 0-220V(AC or DC), Working current: 0-2A, max working pressure: 1.75 MPa. Flow range: 1-30L/min. - 🌟🌊【 Widely Applications】 This flow sensor is suitable for water heaters, pumps, hot tub, boiler, water dispensers, coffee machines, hot card machines, steam equipment, water system, the campus card sales, selling self-help water systems, water treatment equipment, cooling systems, mechanical equipment, instrumentation, pharmaceutical equipment. ## Technical Specifications | Specification | Value | |---------------|-------| | Customer Reviews | 4.2 out of 5 stars 89 Reviews | ## Images ![FS-C01 G1/2" BSP Male Thread Brass Water Flow Switch with Filter 1-30L/min, 0-2A/ 0-220V(AC or DC) - Image 1](https://m.media-amazon.com/images/I/61D8MlZ9ldL.jpg) ## Questions & Answers **Q: Can it work as a 110 volt switch?** A: They state it's safe for 0-220V(AC or DC), Working current: 0-2A. Personally, I would not the wires are something like 28 gauge stranded. you would need to be very careful about wiring. I doubt it would ever pass an Electrical code review with 120v open wiring in contact with a grounded water line. I would suggest running a low voltage DC source to a power relay that could be enclosed in a junction box https://www.amazon.com/dp/B000LESCI2/ref=cm_sw_em_r_mt_dp_2T99ZFSEXHCV82D1CBY9?_encoding=UTF8&psc=1 https://www.amazon.com/dp/B086JTJ5NW/ref=cm_sw_em_r_mt_dp_A3KF31536MM4PBPDE62B?_encoding=UTF8&psc=1 **Q: Am I able to connect a 12 Volt water pump directly to this flow switch?** A: No, it needs to add a relay board. It cannot be directly connected to the circuit. **Q: Can I get a replacement for the reed switch?** A: They did replace mine with no issues. **Q: Is this product lead-free?** A: I suspect it is not lead-free, because it does not have any designation its lead content. Keep in mind that if this is used for regulation of intake to hot water system, the entirety of that plumbing system is full of lead. I got this as a replacement for a very-leaded part (colored silver) made by NTI ## Customer Reviews ### ⭐⭐⭐⭐⭐ work great. *by K***D on May 28, 2025* works fine to turn on my relay, to power my hot water heater elements. ### ⭐⭐⭐⭐⭐ Important Instructions on Use *by M***. on January 30, 2024* Don't make the mistake of connecting a magnetic reed switch directly in line with power as that will either damage it immediately or it just won't last.

The switch closes (Activates / On) with less than 1GPM and stays closed below 1/2 GPM. I think it opens (Deactivates / Off)under 1/4 GPM The only issue is the leads are very thin and broke off during maintenance. I was able to take the switch module off the new assembly and install on the exiting on without turning the water off and changing out the whole body. I'm putting some Hot Glue on the wired connection on the switch body to avoid any other issues ## Frequently Bought Together - DIGITEN FS-C01 G1/2" BSP Male Thread Brass Water Flow Switch with Filter 1-30L/min, 0-2A/ 0-220V(AC or DC) - GESHATEN 3/4” G Thread (BSP) Female to 3/4” NPT Male Connector, Brass BSP to NPT Adapter 3/4 Inch, Industrial Metal Brass G Thread to Pipe Fittings Connect (2 Pack) - GREDIA G1/2" Hall Effect Liquid Water Flow Switch Control Flowmeter Counter Meter for Humidifier Water Dispenser Shower Water Heater Copper BSP Male Thread 1-30L/Min --- ## 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.tn/products/129107478-fs-c01-g1-2-bsp-male-thread-brass-water-flow](https://www.desertcart.tn/products/129107478-fs-c01-g1-2-bsp-male-thread-brass-water-flow) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-06-12*
