Rated for 250V and 15A, it features a reliable SPDT contact system with ±2.5% repeatability error and IP54 protection, making it ideal for water treatment, HVAC, and cooling applications requiring automatic flow-based circuit control. ## Description Features: It is used to measure the dynamic state of the liquid flowing through the pipeline, such as: water, ethylene, and other liquids that have no corrosive effect on copper.When the rate of liquid exceeds or falls below the set rate, the SPDT contacts can turn on one circuit and cut off the other at the same time. The switch is usually used in places requiring interlocking or "cut-off" protection.Repeatability error is about 2.5%, ensure high stability of products.IP54 level, more safer to use.Perfect for water treatment system, central air conditioning, water cooling unit.
