E&H 8I1B Coriolis Mass flowmeter

Comprehensive Technical Guide: E&H 8I1B Coriolis Mass Flowmeter (Promass I 100)

Supplier: ST-YUKE CO., LIMITED

In the realm of precision process instrumentation, the Endress+Hauser Proline Promass I 100 represents a significant advancement in Coriolis flow measurement technology. Designated by the product root E&H 8I1B, this ultra-compact transmitter combines a straight, single-tube titanium sensor with the smallest transmitter housing available today, delivering full functionality on an exceptionally small footprint . What truly sets the Promass I 100 apart is its capability to offer in-line viscosity measurement as an optional output, alongside the standard measurements of mass flow, density, and temperature

As a specialized industrial automation supplier, ST-YUKE CO., LIMITED provides the complete spectrum of E&H 8I1B series with guaranteed authenticity, competitive pricing, and expert technical configuration support.

Product Series Overview: The 8I1B Family

The Promass I 100 is defined by its straight, easy-cleanable single-tube system utilizing TMB® technology, with measuring tubes constructed from Titanium Grade 9. The full-bore design minimizes pressure loss and requires no inlet or outlet straight runs, simplifying installation in space-constrained environments. The “8I1B” root code designates this specific generation with the I 100 ultra-compact transmitter.

The series spans ten primary sensor sizes, including both standard and “Full Bore” (FB) options, to accommodate a vast range of flow rates and ensure optimal hydraulic fit for any application:
