Product headline
The flowmeter for cost-effective measurement and easy monitoring of utility gases.
Suitable for air, nitrogen, carbon dioxide and argon in circular piping or rectangular ducts. -
Sensor features
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.
Insertion version for nominal diameter DN 80 to 1500 (3 to 60″). Installation and removal of sensor without process interruption. Easy installation. -
Transmitter features
Fast and efficient commissioning – guided operating menus. High plant availability – self‐diagnostics and error monitoring. Automatic recovery of data for servicing.
Device in compact version with DC 24 V power supply. 4-20 mA HART, pulse/frequency/switch output. Compact and robust transmitter. -

Field of application
The t-mass B 150 insertion version is suitable for large pipelines or rectangular ventilation ducts. It is 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. 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 circular piping or rectangular ducts.
