Core Technology: Engineered for Chemical Resistance

What truly distinguishes the E&H 8H5B Coriolis mass flowmeter is its uncompromising approach to corrosion resistance. The instrument features a straight, single-tube design with no internal welds or crevices, eliminating potential weak points where corrosive attack could initiate .

Premium Materials for Aggressive Media

The 8H5B series offers two primary material options tailored to specific chemical environments :

Tantalum Version: Ideally suited for highly aggressive acids including hydrochloric acid, sulfuric acid, and nitric acid at elevated temperatures. Tantalum’s exceptional corrosion resistance makes it the material of choice for the most demanding chemical duties .

Zirconium Version: Excellently suited for applications involving strong alkalis and certain acid mixtures, providing reliable performance in environments where even stainless steel would fail .

Heartbeat Technology

Like all modern Promass instruments, the 8H5B incorporates Heartbeat Technology for proactive process management :

Continuous self-diagnosis without process interruption, enabling predictive maintenance

In-situ verification traceable to ISO 9001:2015 requirements, eliminating costly manual checks

Meter verification on demand, supporting regulatory compliance and quality documentation

Additional Benefits

Multivariable Measurement: Simultaneous measurement of mass flow, density, temperature, volume flow, corrected volume flow, reference density, and concentration

Space-Saving Installation: No inlet or outlet run requirements, simplifying piping design and reducing installation costs

User-Friendly Interface: 4-line backlit display with touch control and WLAN access for convenient configuration from outside the housing
