重要な技術的利点
-
Direct Mass Flow Measurement: The t-mass A 150 measures the mass of gas molecules directly. This eliminates the need for additional pressure or temperature compensation sensors, providing a streamlined and cost-effective setup for utility monitoring.
-
Low Pressure and Velocity Sensitivity: Unlike many flow technologies that struggle at low flow rates, the thermal principle allows for accurate measurement even at very low pressures and flow velocities. This is critical for detecting leaks and monitoring gas usage during low-demand periods.
-
Cost-Effective Sub-metering: Designed specifically for energy management and sub-metering, the A 150 offers a high return on investment. It is easy to install, maintenance-free, and creates almost no pressure drop, which helps reduce the energy costs of the compressor system itself.
-
Data Portability: Customer-specific settings are saved directly to the display module. This allows for the “plug-and-play” transfer of configurations from one device to another, significantly reducing the time required for commissioning and servicing.
-
Robust and Compact Design: The device features a rugged aluminum housing and is available as either a display-equipped or blind version. It is powered by a standard DC 24 V supply, making it compatible with most industrial control environments.
-
Integrated Diagnostics: The t-mass A 150 includes self-diagnostics and error monitoring to ensure high plant availability. The guided operating menus ensure that even users with minimal training can perform fast and efficient commissioning.
