Emerson’s radar level transmitters now available with WHG overfill protection approval

Rosemount^® 5300 and 5400 Series level transmitters are now TÜV-tested and approved for overfill protection according to the German WHG regulations

Emerson Process Management announces that its Rosemount^® 5300 Guided Wave Radar (GWR) and 5400 Non-Contacting Radar level transmitters are now available with approvals to the German Water management act (WHG) regulations for overfill protection. Companies in the oil & gas production, refining, petrochemical, chemical, power industries and water and waste will now benefit from the superior performance of Rosemount Radar technology, while ensuring compliance with WHG overfill and water protection requirements.

The transmitters successfully passed the third-party test by TÜV (Technische Überwachungsverein), a German testing authority responsible for testing overfill protection equipment according to requirements of the German WHG institute. Proven instrument accuracy and reliability are key factors in the overfill protection approval process and the Rosemount radar devices were required to pass the comprehensive test of 5000 overfill situations for each transmitter, over the whole temperature range.

The Rosemount 5300 and 5400 Series are high performance 2-wire radar transmitters for challenging level and interface measurements on liquids, slurries and solids. The products take advantage of the company’s 30 years of proven radar expertise and are designed to improve plant profitability through superior reliability, state-of-the-art safety features, effortless handling and unlimited connectivity.

In both the Rosemount 5400 and 5300 Series, the analogue output which provides a continuous level measurement, can also be used to trigger an overfill alarm. The analogue signal is read by the control system which activates an alarm when a predetermined level is exceeded. In addition, the transmitters have an alarm function that indicates if the device has failed.

Innovations such as Direct Switch Technology (DST) for GWR and Dual Port Technology for non-contacting radar make the Rosemount 5300 and 5400 series the most reliable radar transmitters available. DST enhances the capabilities of the GWR to handle disturbances, longer measuring range and lower dielectrics, even with the single probe design. The Dual Port Technology built into the 5400 series enables a stronger signal than other 2-wire radar transmitters, providing better measurement reliability.

The robust designs prevent leakage and ensure reliable performance even under extreme process conditions. Heavy-duty probes are available to meet the extreme temperatures and pressure challenges with multiple layers of protection and advanced echo logics for reliable overfill detection. The 2-wire technology means that installation is fast and inexpensive.

The user-friendly graphical interfaces with wizards, measure-and-learn functionality, suggestions for application specific configuration and PlantWeb™ functionality, ensures the transmitter integrates easily into new or existing control systems. Together with maintenance-free operation and advanced diagnostics, the result is a quicker return on investment with overall improved uptime and enhanced safety.
