Product Critical Technical Advantages
-
Super Duplex Safety: The sensor’s wetted parts are constructed from 25Cr Duplex (UNS S32750), offering maximum resistance to chloride-induced stress corrosion cracking. This makes it the industry standard for handling “sour” gases and liquids containing hydrogen sulfide or high salinity.
-
Extreme Pressure Performance: Capable of operating at pressures up to PN 250 (Class 1500), it delivers premium mass flow accuracy in deep-water production or high-pressure gas injection. The measurement remains independent of fluid density or viscosity fluctuations.
-
Heartbeat Technology for Process Safety: Integrated Heartbeat Technology enables continuous self-diagnostics and documented verification without interrupting the process. This is vital for offshore assets where maintenance costs are high, allowing for the safe extension of recalibration cycles.
-
Efficient System Integration & Operation: The Proline 300 transmitter features a dual-compartment housing with up to three freely combinable I/Os. Its backlit display with touch control and WLAN access allows operators to perform commissioning and diagnostics wirelessly without opening the flameproof enclosure.
-
Multivariable Measurement for Space Savings: A single device captures mass flow, density, and temperature simultaneously. Because the Coriolis principle requires no straight inlet or outlet piping runs, it significantly reduces the overall footprint and the number of potential leak points on expensive deck space.

Field of Application
-
Offshore Platforms: Accurate monitoring of crude oil production, export metering, and high-pressure natural gas flows.
-
High-Pressure Gas Injection: Precise measurement of compressed gases (such as $CO_2$ or natural gas) injected into reservoirs for Enhanced Oil Recovery (EOR).
-
FPSO Units: Ideal for compact deck modules where space-saving installation and vibration resistance are critical for high-precision metering.
