DIGITEN FS-C02 Brass Flow Switch 3/4″ BSP Male Thread 1-30L/min 0-220V

Description

Product Overview

The DIGITEN FS-C02 is a precision‑engineered brass flow switch designed for demanding industrial and commercial water‑handling systems. Constructed from high‑grade brass that meets ROHS standards, the unit offers excellent corrosion resistance and long‑term reliability even in harsh environments. Its 3/4″ BSP male thread (external diameter 25.85 mm) provides a secure, leak‑free connection that can be easily adapted to NPT fittings with Teflon tape, ensuring versatility across a wide range of plumbing configurations.

Operating across a broad voltage range of 0‑220 V AC or DC and a current capacity of 0‑2 A, the FS‑C02 delivers consistent performance for low‑power devices such as water heaters, pumps, and small‑scale boiler systems. The flow sensor detects water movement within a range of 1‑30 L/min, triggering an internal reed switch that can interrupt power to downstream equipment the moment flow ceases. This safety mechanism protects motors and heating elements from dry‑run damage, extending equipment lifespan and reducing maintenance costs.

Key specifications include a maximum working pressure of 1.75 MPa, a compact footprint of 3.66 × 2.52 × 1.14 inches, and a lightweight design of just 5.61 oz. First released on April 16 2019, the FS‑C02 has earned a strong reputation in the market, ranking #3 in the Flow Switches subcategory on Amazon and receiving an average customer rating of 3.7 stars from 159 reviews. Its robust construction, combined with straightforward installation and universal voltage compatibility, makes it an ideal choice for both new installations and retrofit projects.

Usage

Designed for a broad spectrum of applications, the DIGITEN FS‑C02 excels in environments where reliable flow detection is critical. In residential settings, it can be integrated into water heater circuits to automatically shut off heating elements when the water supply is interrupted, preventing overheating and potential fire hazards. Commercially, the switch is well‑suited for coffee machine water lines, hot‑tub circulation systems, and steam‑generation equipment, where precise flow monitoring helps maintain consistent temperature and pressure levels.

Industrial users benefit from the switch’s ability to protect larger pumps and boiler units in manufacturing plants, chemical processing facilities, and campus‑wide water distribution networks. Its waterproof and heat‑resistant properties allow deployment in outdoor installations, such as irrigation control panels and solar‑thermal water heating systems, where exposure to the elements is unavoidable. The FS‑C02’s low power draw (max 2 A) ensures compatibility with a wide range of control panels and programmable logic controllers (PLCs), enabling seamless integration into automated monitoring and safety protocols.

Installation is straightforward: the brass BSP thread can be screwed directly onto the water line, and the electrical leads are terminated using standard screw terminals or quick‑connect plugs. Because the device operates on both AC and DC supplies, it can be paired with existing power infrastructure without the need for additional converters or transformers. This flexibility reduces overall system cost and simplifies maintenance procedures, making the FS‑C02 a cost‑effective solution for both new builds and retrofits.

FAQ

What types of water systems can the DIGITEN FS‑C02 be used with?

The FS‑C02 is compatible with a wide range of water systems, including residential water heaters, commercial coffee machines, hot‑tub circulation pumps, industrial boilers, and irrigation controllers. Its 3/4″ BSP thread fits standard plumbing connections, and the voltage flexibility (0‑220 V AC/DC) allows it to be used with most power supplies found in these applications.

How does the flow switch protect equipment from damage?

When water flow falls below the minimum threshold (1 L/min), the internal reed switch opens, cutting power to the connected device. This prevents motors, heating elements, or other components from operating without water, which can cause overheating, mechanical wear, or catastrophic failure. The rapid response time ensures protection within milliseconds of flow loss.

Is the FS‑C02 suitable for outdoor installations?

Yes. The brass housing is waterproof and resistant to temperature extremes, making it suitable for outdoor use such as irrigation control panels, solar‑thermal water heating systems, and outdoor pump stations. Proper sealing of the electrical connections and use of appropriate conduit are recommended to maintain long‑term reliability.

Can the switch be integrated with a PLC or automation system?

Absolutely. The FS‑C02’s low current draw (max 2 A) and simple on/off output make it easy to connect to programmable logic controllers (PLCs), building management systems, or other automation hardware. The device can be wired directly to digital input modules, allowing real‑time monitoring and control of water flow status within automated processes.

What warranty and support does DIGITEN provide?

DIGITEN offers a one‑year limited warranty covering manufacturing defects and provides access to technical support resources, including installation guides, wiring diagrams, and troubleshooting assistance. Customers can contact the support team via email or phone for prompt resolution of any product‑related concerns.
