Endress+Hauser Launches New Generation of Thermal Mass Flowmeters

Swiss company Endress+Hauser, a supplier of measurement instrumentation, services, and solutions for industrial process engineering, recently launched a line of Proline t-mass F/I 300/500 flowmeters.

The thermal mass flowmeters measure pure gases and gas mixtures, and each has numerous alarm functions as well as bidirectional measurement capability and reverse-flow detection.

Applications for the flowmeters include research and development labs, measuring flare stack and flue gases, and utilities with compressed air, oxygen, nitrogen, or argon. When combined with the comprehensive functionality of the Proline 300/500 transmitters, such as WLAN and configurable I/O, applications can include process control, quantity measurement, leak detection, cost allocation, and energy management.

Even when process and ambient conditions significantly fluctuate, t-mass ensures high measurement accuracy (±1.0%) with excellent repeatability (±0.25%). Gas flows with low pressure and a low flow velocity can also be measured easily thanks to a high turndown ratio. The design makes it possible to operate the device over the long term with minimal maintenance. t-mass F and I can operate at process temperatures up to 356°F (180°C) and pressures up to 580 psi (40 bar).

The t-mass 300/500 measuring system was developed in accordance with IEC 61508, SIL 2, and can be used in safety-related applications. Any device or process errors that may occur are indicated and clearly categorized to NAMUR NE107 standards. The t-mass 300/500 is equipped with alarm functions for immediately detecting unwanted condensate drops on the sensor or pulsating flow, and it can measure and account for gas flows in both flow directions and detect reverse gas flows. It is equipped with Heartbeat Technology – enabling permanent self-diagnostics with the highest diagnostic coverage – as well as metrologically traceable device verification without process interruption.
