    FAQ
    ❯

    A radar level sensor is a high-precision transmitter that uses microwave radar principles to measure liquid level. It calculates the liquid level by emitting electromagnetic wave signals to the liquid surface and receiving the reflected signals. This enables non-contact, continuous, and accurate liquid level monitoring, and is widely used in industries such as chemical, water treatment, food, and energy.

    ❯

    A radar level sensor measures distance by emitting high-frequency electromagnetic wave signals to the liquid surface and receiving the reflected signals. The system calculates the liquid level height based on the echo time, thus achieving accurate measurement.

    ❯

    A radar level sensor is non-contact, transmitting microwave signals through the air; guided wave radar level sensor transmits electromagnetic waves through a probe or cable. The former is suitable for high-temperature and high-pressure environments, while the latter is more suitable for viscous or stirred liquids.

    Good radar level sensor for my silo
    Picked up this radar level sensor last month. Dust was always an issue with my old setup but this one doesn't care at all. The signal is steady even when the silo is full. I had to mess around with the bracket because my roof setup is weird, but whatever, it works. Good buy for anyone in CA. No more climbing up there for manual checks lol.
