The Milesight EM300-DI is a compact LoRaWAN® pulse counter that transforms traditional pulse-output meters into smart wireless meters. It is designed to remotely read metering data and transmit it over a LoRaWAN® network, helping businesses, facilities managers, and building operators improve monitoring without replacing existing metering infrastructure.
Milesight describes the EM300-DI as a LoRaWAN® pulse counter used to remotely read metering data from water meters, turning traditional water meters into smart meters via a LoRaWAN® network. It supports reed switch meters and other passive pulse meters, making it useful for smart water metering and wider pulse-counting applications.
For Irish facilities management and smart building projects, the EM300-DI is especially useful where teams need to monitor water usage, utility consumption, equipment status, or meter pulses across distributed sites. It can reduce the need for manual readings and provide better visibility through a Milesight LoRaWAN gateway and cloud dashboard.
The EM300-DI supports both pulse counter and digital input work modes, with a GPIO dry contact interface, input frequency up to ≤ 2000 Hz, and minimum pulse width of 250 μs. Milesight also lists built-in temperature and humidity sensing, allowing the device to provide additional environmental monitoring alongside pulse-counting data.
The product is compatible with Milesight LoRaWAN gateways and the Milesight Development Platform for remote monitoring and visualised smart data management.
TITAN can supply the Milesight EM300-DI nationwide across Ireland as a standalone sensor or as part of a complete Milesight LoRaWAN monitoring solution, including gateway selection, configuration, cloud dashboard setup, and deployment support.

Irish Use Cases
Facilities Management
The EM300-DI helps facilities teams remotely monitor water meters and other pulse-output devices across commercial buildings, campuses, estates, and multi-site operations. This reduces the need for manual readings and provides better usage visibility.
Smart Buildings
For smart building projects, the EM300-DI can connect existing pulse-output meters into a Milesight LoRaWAN monitoring network. This allows building managers to collect meter data remotely and view it through a cloud dashboard.
Water Meter Monitoring
The EM300-DI is particularly suited to water metering applications. It can help monitor water usage, support leak detection strategies, and improve visibility of consumption across facilities or remote locations.
Utility & Equipment Monitoring
Because the EM300-DI supports pulse counting and digital input, it can also be used with compatible pulse-output devices beyond water metering, depending on the meter or equipment interface.
Remote or Hard-to-Cable Sites
LoRaWAN® connectivity makes the EM300-DI suitable for locations where running network cabling or relying on Wi-Fi is impractical. This is useful for plant rooms, outbuildings, utility rooms, remote assets, and distributed sites.
