It supports a broad voltage range (0-220V AC/DC) and includes a built-in filter to prevent sediment damage. Engineered for durability and easy installation, it safeguards pumps, heaters, and other water-dependent devices by cutting power when flow stops, making it an essential component for efficient, reliable water system management. ## 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 ## 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.

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 | |---------------|-------| | ASIN | B07QRXGT7J | | Best Sellers Rank | #141,055 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #33 in Flow Switches | | Date First Available | April 16, 2019 | | Item Weight | 3.84 ounces | | Item model number | FS-C01ZJ | | Manufacturer | DIGITEN | | Package Dimensions | 3.66 x 2.56 x 1.02 inches | ## 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 ## 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.us/products/129107478-fs-c01-g1-2-bsp-male-thread-brass-water-flow](https://www.desertcart.us/products/129107478-fs-c01-g1-2-bsp-male-thread-brass-water-flow) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-08-09*
