What is remote telemetry unit?

A Remote Telemetry Unit (RTU) is a device used to collect data from various sensors and transmit it to a central monitoring system, often over long distances. RTUs are commonly employed in applications such as oil and gas, water management, and environmental monitoring. They enable real-time data acquisition, allowing for remote monitoring and control of processes, which enhances operational efficiency and decision-making. Additionally, RTUs often include features for data logging and alarm notifications to alert operators of any issues.
