Overview: Proline Promass I 300 (8I3B) Coriolis Flowmeter
The Proline Promass I 300, designated by order code 8I3B, is a high-performance Coriolis flowmeter offered by Endress+Hauser. It stands out for integrating multiple process measurements into a compact, user-friendly unit.
Key Capabilities
- Multivariable measurement: Simultaneously measures mass flow, volume flow, density, temperature, in-line viscosity, and more (e.g., corrected volume flow, reference density, concentration)
- Measurement performance:
- Mass flow (liquid): ±0.10 %
- Volume flow (liquid): ±0.10 %
- Mass flow (gas): ±0.50 %
- Density (liquid): ±0.0005 g/cm³
- Measuring range: 0 to 180 000 kg/h (≈ 0 to 6600 lb/min)
- Temperature range: –50 °C to +150 °C (–58 °F to +302 °F)
- Max. process pressure: Up to PN 100, Class 600, 63K
- Wetted materials: Measuring tube made of Titanium grade 9; connection material is Titanium grade 2, ensuring corrosion resistance and purity
- Nominal diameter range: DN 8 to 80 (⅜ to 3")
