Product Critical Technical Advantages
-
Engineering excellence in remote architecture separates the sensor from the transmitter, allowing the electronics to be mounted up to 300 meters away. This is vital in corrosive environments where ambient fumes could damage sensitive electronics, or where the measurement point is located in a hazardous zone that is difficult for personnel to access safely.
-
Precision engineering for maximum corrosion resistance features a single-tube design available in Tantalum or Zirconium. These exotic materials provide a level of chemical immunity that exceeds stainless steel and nickel alloys, making the H 500 the definitive choice for concentrated hydrochloric, sulfuric, or nitric acids.
-
Integration of operational intelligence through Heartbeat Technology provides a continuous health check and documented verification of the sensor and electronics. For aggressive media applications, this allows for real-time monitoring of tube wall integrity, ensuring process safety and enabling the extension of recalibration cycles without process interruption.
-
Advanced digital integration is enabled by the Proline 500 transmitter, supporting up to 4 freely combinable I/Os and high-speed Ethernet-based protocols. With integrated WLAN access and a built-in web server, commissioning and diagnostics can be performed wirelessly from a safe distance using a standard web browser.
-
Robust multi-variable measurement delivers simultaneous data for mass flow, volume flow, density, and temperature. This single-device approach reduces the number of process penetrations and flange connections in corrosive-resistant piping systems, significantly lowering the risk of potential leaks and reducing maintenance complexity.
-
Space-saving installation is guaranteed as the Coriolis principle is independent of the flow profile. The Promass H 500 requires no straight inlet or outlet piping runs, providing ultimate design flexibility in dense chemical plants, modular skids, or specialized laboratory rigs.
