Field of application
The t-mass A 150 inline device is specially designed for the cost-effective measurement of utility gases, in particular compressed air. It is a trending device aimed at sub-metering applications. its 4-wire technology is contained within a rugged compact aluminum housing. It is orderable either with display or as a blind version. Customer-specific settings are saved on the display and can be transferred from one device to another by means of the display.
- Measuring principle is characterized by a high operable flow range and direct mass flow measurement 
- Suitable for air, nitrogen, carbon dioxide and argon in small line sizes. 
Device properties
- Inline version: nominal diameter DN 15 to 50 (1/2 to 2") 
- Process pressure up to PN 40, Class 300 
- A variety of process connections available 
- Device in compact version with DC 24 V power supply 
- 4-20 mA HART, pulse/frequency/switch output 
- Compact and robust transmitter 
Benefits
- Suitable for air, nitrogen, carbon dioxide and argon in small line sizes 
- Optimal process monitoring – easy measurement even at low pressures and flow velocities 
- Cost-effective measurement – easy installation, negligible pressure loss and maintenance-free 
- Reliable flow trending – multivariable measurement 
- Fast and efficient commissioning – guided operating menus 
- High plant availability – self-diagnostics and error monitoring 
- Automatic recovery of data for servicing
