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.

The "Rod Type Float Switch" is a device that can be used for both water supply and drainage with the same equipment. The position of the rod moves to the right side for water intake and to the left side for drainage, making it an easy-to-handle float switch. The buoy floating on the liquid surface detects the movement following fluctuations in the liquid level and is used for controlling water supply and drainage in tanks, oil tanks, etc., as well as for high and low liquid level alarms. 【Lineup】 ■ AF-107-1 Type ■ AF-700 Type ■ AFA-100 Type *For more details, please refer to the PDF document or feel free to contact us.
