    Description

    EM500-UDL Description

    Overview

    The EM500-UDL is an industrial ultrasonic distance and level sensor for non-contact measurement of liquids and suitable solids from 0.25 to 10 m over LoRaWAN.

    Accurate Non-Contact Detection

    Ultrasonic technology measures corrosive chemicals and diverse liquids with up to ±1% accuracy without contacting the medium.

    Multiple Probing Options

    W050/W100 and C050/C100 probes cover small openings to 10 m tanks, tailoring the sensor to container geometry and range needs.

    Industrial Outdoor Design

    IP67 and UV resistance suit manufacturing, ski resorts and outdoor chemical storage with up to 10 years on a single ER34615 battery.

    Industry Applications

    EM500-UDL Industrial Applications

    Chemical & Petroleum

    Non-contact level monitoring avoids probe contamination in plastic, petroleum and fertilizer industries.

    Industrial Storage

    Tanks with small openings or varying heights use selectable probes for consistent fill-level data.
