E+H 6AAB15-AADAAAASAD23H t-mass A 150 E+H 6BABL4-I5DKCADSAHA1K

The Proline t-mass B 150 is a thermal mass flowmeter manufactured by Endress+Hauser, designed specifically for cost-effective and reliable measurement of utility gases such as compressed air, nitrogen, carbon dioxide, and argon. This device is particularly suited for large pipelines or rectangular ventilation ducts, making it ideal for sub-metering applications and industrial monitoring.

Key Features

• Measuring Principle: Thermal mass flow measurement, which provides direct mass flow readings without the need for pressure or temperature compensation.
• Multivariable Measurement: Simultaneously measures mass flow, gas temperature, and corrected volume (e.g., Nm³, SCFM), offering comprehensive data for process analysis.
• Wide Measuring Range: Capable of measuring flow rates from 20 to 720,000 kg/h (45 to 1,587,600 lb/h) for air, with options extending up to 1,080,000 kg/h (2,381,400 lb/h) depending on calibration.
• Compact and Robust Design: Housed in a rugged aluminum enclosure with an IP66/67 rating, suitable for harsh industrial environments.
• Easy Installation and Maintenance: Features an insertion version that allows for sensor removal without process interruption, facilitating straightforward installation and maintenance.
• User-Friendly Interface: Equipped with a 4-line SD02 display and push-button operation, supporting data backup and transfer of customer-specific settings.

Technical Specifications

• Medium Temperature Range: –40 to +100°C (–40 to +212°F)
• Max Process Pressure: 20 bar g (290 psi g)
• Ambient Temperature Range: –40 to +60°C (–40 to +140°F)
• Housing Material: AlSi10Mg, coated
• Wetted Materials: 1.4404 (316L) stainless steel for the sensor and insertion tube; EPDM, HNBR, or 1.4401 (316) for seals; PEEK 450G for clamping rings.
