The Flow Relay, a flagship product of Aromanikki, excels in strength, elasticity, corrosion resistance, and heat resistance due to our unique flow detection method. Its ability to accurately detect flow even after long-term use leads to cost reduction, resulting in many users reordering. 【Features】 ■ There are no friction sliding parts in the flow detection section, so there are no gaps for water scale or debris to enter, preventing sticking. ■ The leaf spring is made of a special material with high corrosion resistance and durability, showing almost no aging deterioration during its usage period. ■ The flow detection section itself does not need to be replaced for a long time, and the replacement work is simple. └ By regularly replacing inexpensive sealing components (O-rings and gaskets), it is possible to use the product for a long time without degrading performance. * We have compiled frequently asked questions about our "Flow Relay Series" into a Q&A collection, so for more details, please download the PDF document or feel free to contact us.

The "SP-R type" is a revolutionary flow relay (flow switch) developed for liquid flow detection in pressurized piping, featuring a very simple mechanism and excellent piping characteristics. Flow detection is performed solely by the deflection of a leaf spring, with no friction sliding parts such as bearings, ensuring reliable operation unaffected by water scale or debris. Additionally, it can be used in both horizontal and vertical piping. 【Features】 - Reliable operation unaffected by water scale or debris - Sensitive operation with moderate hysteresis characteristics to prevent chattering - Easy to see scale and operating flow rate for accurate settings - Good electrical insulation - Uses oil-resistant and wear-resistant O-rings *For more details, please download the PDF or feel free to contact us.
