Flow relay "SP-R type"

Flow relay "SP-R type"

A highly durable and highly reliable flow relay with no friction or sliding parts and sensitive responsiveness!

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.

Flow relay "AQ-243 type"

Flow relay "AQ-243 type"

It adopts the method of area-type flow meter as its principle mechanism.

The "AQ-243 type" is an area-type flow relay that alarms the increase or decrease of bearing cooling water for pumps and motors, as well as the water supply for gland seals, through electrical contact signals. As resource conservation and effective utilization have become global issues, solving water resource problems is also an urgent task in our country. The flow relay is considered one of the necessary devices during this time. 【Features】 ■ Adopts the area-type flow meter method as its principle mechanism ■ The structure includes a tapered pipe and float in the center of the valve box, with a detection iron core attached above ■ When the measuring fluid flows from below the tapered pipe, the float stops at a buoyant position corresponding to the flow rate ■ The model with an indicator has an indicator point at a location visible from the outside to read the approximate flow rate from the scale based on the float's buoyant state *For more details, please refer to the PDF document or feel free to contact us.

Introducing our unique flow relay with no friction or sliding! *Q&A collection available.

Introducing our unique flow relay with no friction or sliding! *Q&A collection available.

[High Durability, Long Lifespan, High Precision Flow Detection] The leaf spring mechanism, which has no friction sliding parts, significantly extends the replacement cycle of components! Achieving cost reduction!

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.
