LoraWan IP67 Connected Pulse Counting Sensor

With the EM300-DI turn a traditional water meter into a smart meter.

Using LoRaWAN® low power technology, the EM300-DI can operate for up to 5 years on a 4000 mAh battery.

With an IP67 waterproof design, the EM300-DI can be used in a variety of harsh applications.

Combined with our Telemesure.net IoT cloud solution, users can view and manage all measurement data remotely and receive real-time alarms of threshold violations via a browser or remote mobile device.

The EM300-DI is suitable for both indoor and outdoor applications such as agricultural irrigation, industrial water use, water or energy meter reading.
