    EM300-DI

    LoRaWAN® Pulse Counter

    Make it Count

    • Superior Accuracy
    • Embedded with 2 Sensors
    • Data Storage, Retransmission and Retrievability
    • Versatile Applications
    • IP67 Waterproof
    • LoRaWAN® Based
    • Ultra-Low Power Consumption

    EM300-DI LoRaWAN® Pulse Counter is used to remotely read metering data from water meters. It turns existing traditional water meters into smart meters via LoRaWAN® network which further enables easier management and increases the efficiency of water use.

    Superior Accuracy

    • Filter out Interference Signals Automatically
    • Configure the Device as Needed to Secure the Accuracy

    *Stop, Refresh, Clear and Accumulated Counting Supported

    Embedded with 2 Sensors

    EM300-DI LoRaWAN® Pulse Counter is embedded with temperature and humidity sensors for environmental monitoring.

    Data Storage,
    Retransmission and Retrievability

    EM300-DI LoRaWAN® Pulse Counter can store over 2200 sets and retrievability.
    When the connection fails, EM300-DI will continue to collect and store data. Once reconnected, the data collected during that period will be retransmitted to the gateway, thus avoiding data loss. This feature is appropriate for applications that lay emphasis on information and data integrity.

    Versatile Applications

    Agricultural Irrigation
    Industrial Water Use
    Meter Reading

    IP67 Waterproof

    EM300-DI is equipped with IP67 rated enclosure which enables it to function properly even in the most demanding environments.

    Long Battery Life

    • Single battery lasts 5 years
    • Dual batteries last 10 years

    LoRaWAN® Based

    • Compatible with Standard LoRaWAN® Gateway and network servers
    • Data transmission range up to 15 km in rural areas and 2 km in urban areas

    Milesight IoT Cloud

    Easy to Manage Any Time, Any place
