Looking for Fs300a Sensor? FS300A Water Flow Sensor is available at Zbotic with fast shipping across India.
Product Description
A water flow sensor consists of three parts: a plastic valve body, a water flow rotor assembly, and a Hall sensor. It is attached to the water inlet of the water heater to measure the water flow rate. The magnetic rotor in the water flow rotor assembly spins faster or slower depending on the water flow. The Hall sensor sends a pulse signal that corresponds to the rotor speed to the controller. The controller then adjusts the water flow based on the signal.
Precautions for Use:
- Severe impact and chemical erosion are strictly prohibited.
- Throwing or collision is strictly prohibited.
- The temperature of the medium should not exceed 120 degrees.
- If the water quality is too bad, please add a filter at the water inlet.
- Do not use beyond the flow range.
Features:
- This Sensor is Light and Handy in Appearance, Small in Size, and Easy to Install.
- The Impeller Rotates Around the Entire Stainless-Steel Bearing, and the Stainless-Steel Ball is Embedded to Improve the Rotational Sensitivity.
- The Sealing Ring Adopts an Upper and Lower Force Structure and will Never be Affected by Thermal Expansion and Contraction.
- The Hall Element is Imported, and Designed to be Isolated from Water, Epoxy Resin Encapsulated, Anti-Oxidation.
- All Raw Materials are in Compliance with ROHS Testing Standards
- Porous Design and Small Flow Can be Sensed as Usual.
Package Includes:
1 x FS300A Water Flow Sensor

FS300A Water Flow Sensor Overview
The FS300A Water Flow Sensor is a precision device designed to measure liquid flow rates between 1 L/min and 60 L/min. It features a plastic valve body, magnetic rotor assembly, and integrated Hall-effect sensor to deliver real-time pulse signals proportional to water flow for controllers and monitoring systems.
Key Features of FS300A Water Flow Sensor
- Operating Voltage: 3.5 – 24 VDC compatible with Arduino, PLCs, and other controllers
- Flow Range: 1 – 60 L/min for low to moderate water flow applications
- Pressure Rating: Suitable for water pressure up to 1.75 MPa
- Hall-Effect Sensor: Provides stable pulse output proportional to rotor speed
- Durable Construction: Plastic valve body resists everyday wear (avoid chemical erosion)
- Fast Shipping from Zbotic: Quick dispatch across India with tracking
Applications and Use Cases
- Water heater flow monitoring to regulate temperature and prevent dry heating
- Irrigation systems for precise water usage tracking in agriculture and gardens
- Home and industrial water filtration performance testing
- Liquid dispensing machines and beverage automation setups
- DIY smart-water meter projects with microcontrollers
- Cooling loops monitoring in small-scale industrial equipment
How to Use FS300A Water Flow Sensor
Mount the FS300A inline at the water inlet, ensuring the arrow on the body aligns with flow direction. Connect the red wire to your DC supply (3.5–24 V), black to ground, and yellow to the microcontroller input to read pulse signals. Calibrate your controller’s pulse-to-flow conversion and avoid impacts or high-temperature fluids above 120 °C.

Frequently Asked Questions
What type of output does the FS300A provide?
The FS300A emits digital pulse signals via its Hall-effect sensor. The pulse frequency is directly proportional to flow rate, allowing accurate flow calculation when counted by a microcontroller or PLC.
Can I use this sensor with liquids other than water?
This sensor is designed for clean water applications. Avoid corrosive or particulate-laden liquids and ensure medium temperature does not exceed 120 °C to prevent damage.
How should I install the FS300A for reliable readings?
Install the sensor inline with the flow arrow pointing in the direction of water movement. Keep mounting stable to prevent vibration, and ensure there are no air bubbles at the inlet for consistent readings.
