    Overview

    This industrial radar water level sensor provides reliable non-contact level measurement for water and outdoor liquid applications. It supports long-distance detection up to 70m, 4–20mA, HART, RS485/RS232 communication, IP67 protection, and flexible DC/AC power options. Suitable for hydrological monitoring, flood warning systems, reservoirs, rivers, lakes, and smart water management.

    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 generally do not require frequent calibration, as they are precisely calibrated before leaving the factory. If the measurement environment varies significantly, it is recommended to check it every six months to one year.

    ❯

    Low dielectric constants weaken the reflected signal, affecting measurement stability. It is recommended to choose an 80GHz high-frequency radar, which has strong signal focusing and performs better for low dielectric liquids.

    ❯

    Ordinary radar is significantly affected by foam, but high-frequency or FMCW (Frequency Modulated Continuous Wave) radar can penetrate foam layers to measure the true liquid level. If the foam is thick and dense, a guided wave radar transmitter can be considered as an alternative.
