A highly durable and highly reliable flow relay with no friction or sliding parts, featuring sensitive responsiveness!
The "SP-RN type" is a revolutionary flow relay (flow switch) developed for liquid flow detection in pressurized pipelines, featuring a very simple mechanism and excellent pipeline characteristics. Flow detection is performed solely by the deflection of a leaf spring, with no friction sliding parts such as bearings, ensuring reliable operation without being affected by water scale or debris. Additionally, it can be used in both horizontal and vertical pipelines. 【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 setting ■ Good electrical insulation ■ Uses oil-resistant and wear-resistant O-rings *For more details, please download the PDF or feel free to contact us.

Company information
At Aromanikki, we design, manufacture, sell, and maintain fluid control devices and dam control devices, including flow relays, as well as sell and maintain environmental equipment. Our flagship product, the flow relay, utilizes a unique flow detection method made possible by our proprietary plate spring, which excels in strength, elasticity, corrosion resistance, and heat resistance. This design eliminates gaps in the flow detection area where water scale or debris could enter (friction sliding parts), ensuring that components do not seize even after long-term use, allowing for accurate flow detection. Flow relays manufactured by the former Nikko Kogyo Co., Ltd. can be replaced. Please feel free to contact us if you have any requests.
