GE Introduces Sentinel™ Custody-Transfer Natural Gas Flowmeter

Billerica, Massachusetts, October 14, 2004 .

GE Infrastructure Sensing, a leading provider of precision sensing products, systems and services, today introduced the Sentinel™ product line, a high-accuracy, multi-path ultrasonic flowmeter specifically geared to the fiscal custody-transfer of natural gas. The Sentinel system can be used for such typical natural gas applications as transmission, distribution and storage, or for any measurement point where high accuracy is needed.

Sentinel is available in pipe sizes ranging from six to 24 inches and meets AGA9 criteria. The system employs a two- diametrical-path, single-traverse meter body design with a 10 diameter upstream pipe run and a flow conditioning plate. This configuration provides sufficient flow conditioning to handle any upstream flow disturbance and provides a well-known flow profile at the meter body.

“GE Infrastructure Sensing has long been a leader in ultrasonic flowmeter technology, especially in clamp-on technology and for specific applications like flare gas flow measurement,” said Paul Ceglia, flowmeter product line manager for GE Infrastructure Sensing. “The Sentinel provides our customers with a new approach to custodial transfer, and applies our advanced transducer and signal processing technology to fiscal natural gas flow measurement.”

Advanced ultrasonic transducer technology, combined with signal processing optimized for speed and robustness, give the system the capability to operate even in air at atmospheric pressure—important for field verification of the meter system during commissioning.
