E+H Proline t-mass F 500 Remote Thermal Mass Flowmeter

Precision Remote Gas Mass Flow Measurement

Accurate gas measurement and compressed air monitoring are vital for managing energy costs, improving plant efficiency, and maintaining process safety across heavy industrial facilities. The Endress+Hauser Proline t-mass F 500 Thermal Mass Flowmeter delivers a reliable inline solution for measuring utility gases, fuel gas lines, and dynamic gas mixtures. Utilizing thermal dispersion technology, the t-mass F 500 measures gas mass flow directly, eliminating the need for additional pressure or temperature sensors and complex flow calculation computers.

Remote Transmitter Architecture for Severe Field Conditions

A key operational feature of the Proline t-mass F 500 is its remote transmitter housing, which can be installed up to 300 meters (1,000 feet) away from the inline sensor. This split design allows the sensor to operate reliably in high-vibration pipes, elevated temperature zones, or hazardous classified locations, while placing the display and user interface in an accessible, safe location for operators.

The transmitter housing is available in durable aluminum or hygienic stainless steel with IP66/67 (NEMA 4X) ingress protection, ensuring long-term resistance to weather exposure and aggressive industrial atmospheres.

Dynamic Gas Engine Software for Flexible Gas Compositions

The E+H t-mass F 500 integrates Endress+Hauser Gas Engine software functionality, allowing operators to select from pre-programmed standard pure gases or create customized gas mixtures directly in the field.

When process parameters change—such as shifting natural gas compositions, fluctuating biogas streams, or variable nitrogen blanketing flows—the device automatically recalculates thermal properties and flow calibration curves in real time. This flexibility ensures continuous measurement accuracy without requiring factory recalibration or line shutdowns.

Low Head Loss & Onboard Diagnostics

Mechanical gas meters often cause line pressure drops, experience mechanical wear, and drift out of calibration over time. The t-mass F 500 features a robust inline sensor design with no moving parts exposed to the fluid stream, completely eliminating head loss and mechanical maintenance.

The device features built-in Heartbeat Technology, providing continuous self-diagnostics, monitoring, and traceable field verification without interrupting line flow. Audit-ready verification reports can be generated directly on-site to satisfy quality and environmental audits.

Supported industrial communication protocols include 4 to 20 mA HART, Modbus RS485, PROFINET, EtherNet/IP, PROFIBUS PA, and Foundation Fieldbus, ensuring effortless integration into SCADA, PLC, or DCS networks.
