Smart irrigation

 The EM300-DI monitors water consumption and environmental factors, such as temperature and humidity, across multiple fields or irrigation lines. Measurement per zone ensures efficient water distribution and supports data-driven decisions in irrigation.

• Minimises water waste through accurate allocation

• Reduces operational costs through automated monitoring

• Improved health and yield of crops





Industrial water management

In industrial environments, high water consumption, leakage risks, and uneven usage make accurate monitoring crucial. The pulse counter addresses these challenges by providing reliable pulse counting and real-time data, enabling managers to control costs and prevent water loss.

 • Lower water-related costs

• Early detection of leaks and anomalous consumption

• Improved operational efficiency




Municipal utilities

By equipping existing meters with the EM300-DI LoRaWAN® pulse counter, municipalities can transition to wireless remote reading, significantly reducing manual work and operational costs while maintaining reliable consumption data.

• Reduced costs and effort for manual meter reading

• Cost-effective upgrade without replacing all meters

• Consistent, accurate data for citywide water management





Smart buildings

The EM300-DI supports accurate water data collection for tenant billing and ESG reporting, and provides fraud-resistant, traceable data required for certifications for green buildings, such as LEED and BREEAM.

• Accurate billing to tenants and tracking of consumption

• Reliable ESG and legally required reporting

• Supports compliance with green building standards and sustainability goals
