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.
