.PLT’s patented Wide Flag Indicator uses a solid, one piece magnetic flipper or flag design. With the entire magnetic flag being magnetic, this utilizes a max surface area for a stronger magnetic couple to the float. Furthermore, the strong magnetic poles provide an interlock between the flags in which only the float can break the connection- preventing the common reading failure of flags rotating or “checker-boarding” above the liquid level. This provides a truly reliable physical level reading that operators can see from over 300 ft. away. More information is and video available through Vector Controls.
