Due to the absence of springs, there is minimal aging change, and there are no issues with rust or corrosion.
The lead switch fixed outside the main body is turned ON-OFF by a magnet inside the movable flapper of the water passage. It uses a reed switch, which offers high accuracy, capable of detecting flow rates from 0.5L/min as standard, and from 0.3L/min as an option (for water). Since it does not use a spring, there is minimal aging change, and there are no issues with rust or corrosion. For more details, please contact us or refer to the catalog.
