Product Critical Technical Advantages
-
Remote Installation Flexibility: The transmitter can be mounted up to 300 meters away from the sensor using a standard connection cable. This is a vital safety feature for offshore platforms, as it allows personnel to access process data and perform maintenance far from high-pressure piping or hazardous fumes.
-
Super Duplex Material Integrity: The measuring tubes are constructed from 25Cr Duplex (UNS S32750), providing world-class resistance to stress corrosion cracking. This ensures the mechanical longevity of the meter when exposed to the harsh salt-spray environments and “sour” hydrocarbons typical of offshore production.
-
Extreme Pressure Engineering: Designed to handle pressures up to PN 250 (Class 1500), this meter maintains premium accuracy in the most demanding upstream conditions. The dual-tube design remains stable and precise, unaffected by fluctuations in fluid viscosity or density.
-
Heartbeat Technology for Smart Verification: Built-in Heartbeat Technology provides continuous self-diagnostics and documented, compliant verification without process interruption. This allows operators to monitor the health of the 25Cr Duplex tubes in real-time and extend recalibration intervals with complete confidence.
-
Advanced Connectivity & Data Access: The Proline 500 transmitter supports up to 4 freely combinable I/Os and high-speed Ethernet-based protocols. With integrated WLAN and a built-in web server, commissioning and troubleshooting can be performed wirelessly from a safe distance using any standard web browser.
-
Efficient Multivariable Output: A single installation captures mass flow, volume flow, density, and temperature. Because no straight inlet or outlet piping runs are required, the O 500 significantly reduces the footprint and complexity of high-pressure offshore modules and fiscal metering skids.

Field of Application
-
Offshore Production: The definitive choice for measuring high-pressure crude and natural gas on FPSOs and platforms where the transmitter must be safely located in a control room or rack.
-
Deep-Water Injection: Accurate measurement of compressed gases or chemicals being injected at extreme pressures into subsea wells.
-
Fiscal Metering Skids: Used in large-scale custody transfer systems where the highest accuracy is required and remote data integration is essential for plant-wide monitoring.
-
Sour Gas Processing: Ideal for high-pressure gas streams containing H2S where material integrity and remote operation are non-negotiable safety requirements.
