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 subetering 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
