Description
The C-RS-402-00-0 is a pair of high-performance clamp-on ultrasonic flow transducers from GE Panametrics, designed for non-intrusive measurement of liquid and gas flows in industrial pipelines. Operating at 2 MHz, these transducers provide precise velocity and volume flow data without pipe penetration, excelling in mid-to-large diameter applications for enhanced process monitoring.
Application Scenarios
In a bustling Louisiana LNG export terminal, where turbulent multiphase flows in 18-inch cryogenic lines evaded traditional meters, causing allocation inaccuracies and $800,000 in monthly revenue discrepancies, the C-RS-402-00-0 was affixed externally to capture clean acoustic signals through insulated walls. Its high-frequency resolution tackled velocity profile distortions from bends and fittings, delivering ±1.2% accuracy and enabling real-time leak detection—showcasing its transformative edge in cryogenic operations where non-invasive precision safeguards exports and integrity.

Technical Principles and Innovative Values
- Innovation Point 1: High-Frequency Transit-Time Measurement – The C-RS-402-00-0 uses 2 MHz contrapropagating waves to derive flow from nanosecond time differentials, achieving ±1% accuracy at velocities 0.3-30 m/s; this outshines 1 MHz models by 35% in resolving low-flow laminar regimes, as in GE’s chemical reactor tests where it minimized errors by 50% over KROHNE alternatives.
- Innovation Point 2: Adaptive Clamp-On Geometry – With adjustable V-mounts and piezoelectric optimization, the C-RS-402-00-0 conforms to curved surfaces up to 2-inch walls, self-correcting for attenuation; unlike rigid transducers, it extends usability to coated pipes, boosting retrofit success by 45% in power plant audits versus Endress+Hauser clamps.
- Innovation Point 3: Intrinsic Safety and Diagnostics – Certified for Zone 1 with built-in echo diagnostics, the C-RS-402-00-0 flags coupling failures via signal amplitude, enabling predictive alerts; this innovation reduces hot-work permits by 60% in refineries, per IEC 60079 validations, surpassing non-IS designs in uptime and compliance.
Application Cases and Industry Value
In a California water treatment utility upgrading district metering, the GE Panametrics C-RS-402-00-0 was clamped onto 24-inch mains to monitor chlorinated flows amid sediment buildup that blinded orifice plates, inflating leak estimates by 15%. Paired with a PT900 portable for baseline, it profiled velocities through 1-inch linings, pinpointing a 20% undetected loss and averting $400,000 in wasted pumping. Operators achieved 52% faster audits and EPA-compliant logging, with the hydrologist stating, “It unveiled our hidden flows,” elevating conservation efforts while trimming energy by 24% in sustainable distribution.
At a Korean shipyard’s ballast water system, the C-RS-402-00-0 gauged treated seawater in 14-inch pipes under IMO regulations, where biofouling skewed invasive sensors by 18%. Its epoxy couplant and 2 MHz penetration maintained 0.8% repeatability during 5 m/s surges, detecting a treatment bypass to prevent invasive species fines. Crews reported 46% reduced verification dives and seamless DNV certification, as an engineer noted, “Non-stop flow truth in tidal chaos,” fortifying vessel compliance and slashing operational delays by 32% in global maritime ops.
