Modernizing Gas & Pipeline Pressure Testing with the Additel ADT685Ex

In gas transmission, distribution, and pipeline operations, pressure measurement is not just a maintenance task, it is a critical safety and compliance function. From leak testing and relief valve verification to commissioning and routine inspections, field technicians are required to deliver accurate, traceable, and repeatable pressure data, often in hazardous environments.

A major North American gas utility recently modernized its field operations by integrating the Additel ADT685Ex Digital Pressure Gauge into its workflow, replacing traditional analog gauges and manual data recording practices. The result: improved accuracy, reduced operational risk, and a streamlined testing process aligned with modern gas industry requirements.

One Instrument for Multiple Gas Testing Tasks

Designed for use in hazardous areas, the ADT685Ex is an intrinsically safe digital pressure gauge engineered for demanding gas and pipeline applications. In field operations, it effectively replaces multiple instruments, including analog pressure gauges, chart recorders, barometers, and stopwatche into a single, portable device.

Key gas-industry use cases include:

• Pipeline pressure and leak testing
• Relief valve verification
• Peak pressure monitoring during transient events
• Field calibration and verification activities
• Commissioning and maintenance of gas assets

Built-in leak test functions allow technicians to detect pressure decay without external tools, while peak pressure capture ensures critical events are recorded accurately—both essential in gas safety management systems.

Digital Data Integrity for Gas Utilities

Manual data logging is a known source of error in gas operations. The ADT685Ex addresses this challenge by enabling digital data recording directly at the test point. Pressure data can be stored internally and synchronized via Bluetooth or USB with Additel software, ensuring full traceability and reducing reporting errors.

With pressure ranges up to 60,000 psi (4,200 bar) and accuracy up to 0.02% FS, the ADT685Ex delivers laboratory-grade performance in the field—supporting compliance, audits, and operational reliability across gas networks.
