The magnetic reed float switch (zero pressure) is a reliable sensor specially designed for water level detection in gas water heater tanks. Using magnetic coupling with a non-contact detection method, the float moves up and down with the water level, and the magnetic field activates the internal reed switch to open or close the circuit. This ensures high sensitivity, leak-free operation, and long service life. It is suitable for household and commercial gas water heaters, including instant and storage types, especially for low-pressure or zero-pressure side detection.

• Durable Copper Material - Ensures long-lasting performance and corrosion resistance.
• Accurate Flow Detection - Provides reliable water flow sensing for stable operation.
• Magnetic Sensor Design - Delivers quick response and consistent control.
• Wide Application - Suitable for most gas water heater models.
• Easy Installation - Compact structure allows simple replacement and maintenance.

Q1: Is it suitable for all gas water heaters?

A: Designed for zero/low pressure tanks, fits most storage and some instant heaters.

Q2: Should I choose NO or NC?

A: NO triggers when water enters; NC triggers when water is empty. Dual-contact available.

Q3: Is installation easy?

A: Yes, side/top mount supported. For best results, let a technician install.

Q4: Will scale affect the float?

A: Slight scaling may occur. Check and clean every 6–12 months; stainless float recommended for hard water.

Q5: Can it be customized?

A: Yes, cable length, materials, and certifications (CE, RoHS, UL) are customizable.

Q6: Is there a warranty?

A: 12-month standard warranty with repair or replacement.
