Ultrasonic flowmeter for pipeline monitoring
Honeywell’s USM GT400 Ultrasonic Flowmeter is designed to reduce the amount of effort needed to maintain pipeline metering. The USM GT400 measures the volume of natural gas at every stage of its movement, storage and utilization, which is important because the volume of gas transported via pipelines to consumers is metered for billing purposes.
The USM GT400, which is compliant with cloud based CEESmaRT technology, provides stability during flow perturbations thanks to its direct-path technology with six measuring paths on three levels. The paths are arrayed in an "X" pattern in horizontal planes. This orientation enables measurement of swirl, cross-flow and asymmetry, as well as transparent path velocity weighting per the Gauss-Chebyshev profile model for compressible fluids.
The USM’s electronics are used to handle path-specific measurements while optimizing internal diagnostics. It includes speed of sound (SoS) and flow velocity calculations, signal processing and data storage capabilities, and can interface to flow computers, gas chromatographs and SCADA systems. The meter’s transducer – which operates at standard frequencies of 120 or 200 kHz, and alternate frequencies are available for noisy environments – consists of piezoelectric crystals fully encapsulated in titanium housing for resistance to dirt. This unique configuration is field-replaceable under pressure.
Windows-based RMGViewUSM software allows manufacturers to monitor the health of the flowmeter, alerts users to upset conditions, and provides diagnostics for alarming. It also allows direct access to the electronic measuring system via a PC to read out and change parameters, represent measured values, and create test certificates and data sheets.
