Data Acquisition & Transmission
WellRanger Multi-Gauge Data Acquisition and Control System
Designed for Single or Multi-drop Gauge Systems in Any Environment
The WellRanger is a Surface Read Out (SRO), Data Acquisition and Collection System (DAS) for downhole Pressure/Temperature gauges primarily used in the oil and gas industry.
Designed for digital signal transmission, the system is surface configurable for addressing multiple gauge deployments on a single line as well as multiple gauge deployments on multiple lines.
The WellRanger is also capable of handling downhole fault protection and current limiting, a requirement of most, if not all multi-drop systems currently deployed.
