SAT120 Satellite/Cellular SCADA Communications for Mobile Well Testing

The SCADALink  SAT120 Modem can be an flexible cost effective communications solutions for Mobile Well Testing.

SAT120’s Dual Mode Satellite/Cellular communications ensures communications in the most remote areas.  With dual mode communications, cellular will be used as primary communications to provide low cost communications with fail over to satellite communications ensure connectivity at sites without cellular communications.

The SAT120 has RS232 and RS485 Serial Communications and  4 I/O (DI/AI).  RS485 connectivity allows direct connectivity to EFM and RTU systems. The SAT120 I/O can be used to connect to additional I/O as needed on well testing and fixed well site applications.

SAT120 is supported by the SatSCADA Platform which provides alarm callout, data archival, & data visualization. More about SatSCADA…


Transparent Data Communication

The SAT120 allows transparent data communications from SCADA Hosts, Well Testing Applications, and EFM configuration programs to flow computers.  This allows  EFM and RTU to be remotely accessed, polled and downloaded including complete download of data logs and audit trails.

SAT120’s Dual Mode Satellite/Cellular Communication

With dual mode communications, cellular can be used as primary communications to provide low cost communications with fail over to satellite communications in remote areas to ensure connectivity at sites with spotty or no cellular communications. SAT120 can be configured as Satellite Only, Cell Only or Satellite/Cellular Fail-Over to provide the optimal communication costs. For mobile well testing applications, satellite  may be used in remote locations without cell service.


EFM & RTU Configuration Support with LOI Override Feature

Scanner 2000

The SAT120 provides complete support of EFM/RTU Configuration Applications.  The SAT120 Config Override Feature allows EFM and RTU  connectivity without termination of SCADA communications connectivity to EFM/RTU.  When RTU/EFM configuration software is connected, SCADA connectivity is temporary overridden. This allows for full remote configuration and maintenance of the connected EFMs. SCADA connectivity to returned once the EFM/RTU configuration application is terminated.

Web Browser and Smartphone Viewing of Tags and Trends

The SatSCADA Web Client provides Tag and Trend Views via web browsers on a computer or smartphone. The Web Client Views are based on points configured in the SAT120.  This feature provides cost effective visibility to key Tag Points on the Well Test Unit.

Alarm Callouts

Alarm Conditions for Alarm Points configured in the SAT120 will initiate Email and SMS Notifications from SatSCADA Server.


The SAT120 can be configured to report Tag Data to the SatSCADA Server on a daily, hourly, or interval schedule;  alarm condition, or user demand.  These points  can be trended by the SatSCADA Web Application.

Low Power Operation

The SAT120 features low power operation.   Cost effective remote measurement packages can be implemented using the SAT120.
