YK-FQL. Float Level Transmitter

The FQL series float level transmitter (Magnetostrictive level meter) consists of a measuring tube, float, reed switches, and other key components. Multiple reed switches are installed inside the sensor. As the magnet-equipped float moves up and down with the liquid level, it activates reed switches at different positions, causing changes in the output resistance and generating a level signal.

It is widely used in industries such as oil refining, chemical processing, papermaking, food production, and wastewater treatment. It is suitable for open or closed tanks, as well as underground tanks, enabling level display, alarm, and control in control rooms. The measured media can include water, oil, acids, alkalis, and industrial wastewater, whether conductive or non-conductive.

Product Principle

The level transmitter consists of a body, float, flange cover, and level transmitter assembly. As the float outside the body moves with the liquid level, it actuates the reed switches inside the body to open or close, converting the level position into an electrical signal transmitted to the control center. It can also be integrated into a computer-based centralized monitoring system.
