    Overview

    This non-contact radar liquid level sensor is designed for accurate tank level measurement in harsh liquid environments. It measures levels up to 20m with 26GHz microwave technology and supports 4-20mA, RS485 or HART output for industrial automation systems. Suitable for corrosive liquids, volatile liquids, vapor-filled tanks, wastewater treatment, water storage tanks, chemical tanks, and continuous level monitoring.

    Feature

    • 10° narrow beam design: The radar level sensor concentrates energy within a narrow beam, delivering powerful medium penetration and improved echo stability.
    • Wide application range: Features a waterproof, dustproof, and corrosion-resistant design for reliable use in harsh industrial environments.
    • 304 stainless steel housing: Durable, wear-resistant, and shockproof construction ensures long-term stability and extended service life.

    FAQ
    ❯

    Radar level sensors can measure water, oil, acid and alkali solutions, slurries, and some solid powders. Different models are designed for liquids or solids; the appropriate model must be selected based on the characteristics of the medium.

    ❯

    Yes, some models can withstand temperatures up to +250℃ or even higher. High-temperature sensors should be selected, along with suitable process connections and sealing materials.

    ❯

    Yes, when used with acid, alkali, or salt solutions, PTFE (polytetrafluoroethylene) or PVDF antenna materials should be selected. The housing should also be made of corrosion-resistant stainless steel or plastic.
