    Ultrasonic Level Sensor DF550

    • Weight:No parameters
    • Brand :Ultrasonic Level Sensor
    • No.:DF550

    The F550 is one type of ultrasonic level sensor which measure the air height in the container directly and calculate the level height based on the total height of the container. The resolution is 1mm or 0.1%FS (the bigger value).

    1. Detailed information

    1. Overview

    The F550 is one type of ultrasonic level sensor which measure the air height in the container directly and calculate the level height based on the total height of the container. The resolution is 1mm or 0.1%FS (the bigger value).

    It is applicable for the close container or open container.  Furthermore it can calculate the volume of the container or the liquid. As with RS485, it is easy to integrate into the embedded system or SCADA.
