Product Categories

The current product lineup focuses on level measurement and flow monitoring. The most widely distributed models include:

Liquid level detection sensors

• Float-type level switches: Mechanical switches designed to detect high or low liquid levels in tanks. Available in compact sizes and different mounting styles, suitable for both open and closed tanks.

• Ultrasonic level sensors: Use ultrasonic waves to measure liquid surface distance. Ideal for corrosive or hygienic environments where no-contact measurement is preferred. Options include standard and compact designs.

• Radar level sensors: Suitable for extreme industrial conditions such as high temperature, high pressure, or vapor-heavy tanks. Radar ensures precise readings even in challenging environments.

• Pressure-based level sensors: Measure liquid level indirectly by detecting bottom pressure in sealed tanks. Used for static liquids and pressurized systems.

Flow switches

• Paddle or piston-type flow switches: Monitor flow presence in pipelines. If the flow stops or exceeds limits, the switch sends a signal. These devices are available with threaded or flange connections and withstand high pressures and harsh media.

Level display units

• Signal display panels: Receive input from level sensors and display the current liquid level as a percentage or digital value. Some models include alarm settings for high and low thresholds.

Key Advantages

• Product specialization: By focusing solely on level and flow technologies, Daehan achieves superior accuracy and stability.

• Controlled manufacturing: All production is based in Korea for strict quality control.

• Cross-industry compatibility: Solutions are applied in chemical plants, food factories, healthcare systems, and liquid storage facilities.

• Adaptable designs: Models can be customized to suit tank size, material, and operating conditions.
