Application and Solutions:
Remote Terminal Unit (RTU) is the basic unit of Supervisory Control and Data Acquisition (SCADA) system. By acquiring the data on site, SCADA system can monitor and control the production system with its production units remotely and dispersedly distributed. Composed of several to hundreds of I/O points, RTU can be installed near the measuring site to monitor and control the field signals and industrial equipment. RTU has two basic functions: data acquisition and processing, and data transmission. However, most RTUs have many more advanced functions such as PID control, logic control and flow accumulation, computing, etc.

Based on the features and functions, ECHO's RTU can be used in any kind of automation and control systems, such as SCADA, DCS, and FGS, in many industries listed but not limited as below. With years of industry expertise, ECHO can provide you with total solutions to all your needs.
1) Oil and gas well heads monitoring and control;
2) Oil and gas pipeline supervision, metering and control;
3) Natural gas and heating distribution;
4) Water and wastewater treatment plants;
5) Street lights monitoring and control;
6) Environment protection;
7) Other systems or device where temperature, pressure, flow etc. need to be supervised and controlled.
