Endress+Hauser Thermal Mass Flowmeters

Provides direct mass flow measurement for gases and selected liquid applications without the need for pressure or temperature compensation. Based on thermal dispersion technology, these instruments are designed for reliable monitoring of industrial gases, compressed air, nitrogen, biogas, and process air systems. The portfolio includes inline and insertion versions suitable for small pipelines up to large ducts.

Product Overview

The thermal mass portfolio includes:

• Proline t-mass F 300 / F 500 – Inline flanged versions
• Proline t-mass I 300 / I 500 – Insertion versions for large pipes and ducts up to DN 1500 (60″)
• Proline t-mass T 150 – Compact thermal flowmeter for liquids
• Flowphant T DTT31 / DTT35 – Flow switches for monitoring flow and temperature

These devices provide stable long-term performance and are designed for industrial process environments requiring reliable mass flow data.

Integration & System Compatibility

Thermal mass flowmeters integrate with PLC, DCS, and SCADA systems via analog and digital communication interfaces. The 500 transmitter platform supports remote installation and expanded I/O capability for advanced system integration.

Why Thermal Mass Flow Measurement

Thermal mass technology directly measures gas mass flow without requiring additional pressure or temperature inputs. This simplifies installation and reduces system complexity. The insertion versions allow cost-effective measurement in large pipelines without full-bore meter replacement.
