Overview

Engineered for durability and reliability, this solid brass inline water flow switch is purpose-built for water flow detection and equipment protection in plumbing, heating, and fluid control systems. The robust all-brass construction — reinforced with stainless steel mounting screws — makes it an ideal upgrade over plastic-bodied switches in applications where pressure, temperature, or media demands a tougher build.

With its G1/2″ male inlet and G3/8″ male outlet, this flow switch is designed for easy inline installation and integrates seamlessly into existing pipework. Rated IP65 for dust and water resistance, it performs reliably in wet, outdoor, or semi-industrial environments where moisture exposure is a concern.

How It Works

This flow switch uses an internal magnetic reed switching mechanism to detect the presence or absence of water flow:

• When water flows through the body at or above the trigger flow rate, the internal mechanism is displaced, activating the reed switch and outputting an “ON” signal to the connected control system — allowing pumps, heaters, solenoid valves, or other equipment to operate.
• When water flow stops, the reed switch returns to its default state and outputs an “OFF” signal, shutting down connected equipment and protecting against dry-run or no-flow damage.

The result is a fast, clean, and repeatable digital switching action that integrates directly with PLCs, relay boards, microcontrollers, or any standard control system.

Key Features

• Full brass body construction – Superior strength, pressure resistance, and corrosion resistance vs. PP or plastic switches
• Stainless steel securing screws – Added structural integrity and resistance to rust and loosening over time
• G1/2″ male inlet × G3/8″ male outlet – Dual-size threaded ports for flexible installation in mixed-size pipework
• IP65 protection rating – Fully dust-tight and protected against water jets; suitable for outdoor and wet environments
• Reed switch technology – Reliable, low-maintenance flow detection with no moving electrical parts in the flow path
• 0.5A overload current rating – Safe, signal-level switching for integration with relay or control board circuits
• Compact, robust form factor – Dense brass block design resists vibration and mechanical stress in high-pressure lines

Specifications

Applications

• Electric water heaters (instantaneous & storage type)
• Boiler and heating system flow protection
• Pump dry-run prevention systems
• Solar water heating controllers
• Industrial process flow monitoring
• Water purification and RO filtration systems

Why Choose Brass?

Keep your water systems running safely and efficiently with this G3/8″ PP inline water flow switch. Designed to detect the presence or absence of fluid flow inside a pipeline, this compact reed-type flow switch sends a real-time digital switching signal to your control system — protecting equipment from dry-running, overheating, or operating without water. Built from durable polypropylene (PP) with an IP65-rated sealed body, it’s suitable for a wide range of residential, commercial, and light industrial fluid control applications.

How It Works

This flow switch is normally open (NO) by default:

• When water flows through the pipeline, the internal mechanism is activated by the flow, closing the reed switch and outputting an “ON” signal to the connected control system — enabling pumps, heaters, or other connected equipment to operate.
• When water stops flowing, the reed switch returns to its open state and outputs an “OFF” signal, halting system operation and protecting connected equipment from running dry.

This simple, mechanically driven mechanism requires no external power for flow sensing, making it highly reliable and low-maintenance over its rated 1,000,000-cycle lifespan.

⚠ Note: This switch is designed for low-power signal control only and is not suitable for directly switching high-power loads (e.g., 220V high-current devices). Custom 220V-rated versions are available — please contact us for details.

Upgrade your fluid control system with this premium 304 stainless steel inline water flow switch, designed for reliable, long-life flow detection in demanding industrial and commercial environments. Unlike plastic-bodied alternatives, this flow switch features a full 304 stainless steel shell and probe, offering exceptional resistance to corrosion, high pressure, and harsh media. Whether you’re protecting pumps from dry-running, controlling heating systems, or monitoring process lines, this switch delivers fast, accurate, and repeatable switching performance.

How It Works

This flow switch uses a spring-loaded magnetic core displacement principle to detect flow without requiring external power for sensing:

• When fluid in the pipeline reaches or exceeds 0.75 L/min, the flowing water displaces the internal magnetic core against the reset spring. This movement causes the magnetic source to generate a magnetic control effect, triggering the sensor to output a “1” (ON) switching signal. This signal is sent to the equipment’s control system where, after power amplification, it activates the desired control function — such as starting a pump, enabling a heater, or triggering an alarm.
• When the flow rate drops below 0.75 L/min, the reset spring pushes the magnetic core back to its original resting position. The magnetic source returns to its default state, causing the sensor to output a “0” (OFF) switching signal, which halts the system’s operation and provides protection against low-flow or no-flow conditions.

This automatic, mechanically driven mechanism ensures consistent, reliable protection with no need for manual intervention or recalibration under normal operating conditions.

Key Features

• Full 304 stainless steel construction – Shell and probe both made from 304 SS for maximum corrosion resistance and compatibility with water, mild chemicals, and industrial fluids
• IP65 protection rating – Fully dust-tight and protected against low-pressure water jets, suitable for wet or outdoor environments

Why Choose Stainless Steel Over Plastic?

Ensure safe, precise water and power control in your water heating system with this high-quality G1/2″ inline water flow switch. Engineered for vertical installation, this flow switch is specifically designed for use in instantaneous (tankless) electric water heaters — controlling water flow and power activation simultaneously — as well as storage-type electric water heaters, where it manages water outlet and power shutoff functions. Its compact, all-plastic construction makes it lightweight, corrosion-resistant, and easy to install in both residential and light commercial applications.

How It Works

This flow switch operates on a magnetic displacement principle, requiring no external power source to detect flow. When water enters the switch body and the flow rate reaches or exceeds 1.0 L/min, the internal magnetic core is physically displaced by the water current. This movement causes the magnetic source to generate a control effect, triggering the switch to output an “ON” signal. This signal is fed into the equipment’s control system, which executes the appropriate control action (e.g., activating a heating element or pump).

When the flow rate drops below the set threshold (0.75–3 L/min range), the magnetic core returns to its resting position, and the switch outputs an “OFF” signal, causing the control system to perform the reverse function — safely shutting off power or stopping the pump. This automatic, flow-driven mechanism provides reliable, responsive protection against dry-fire and low-flow hazards.
