Critical Technical Advantages
-
Large Scale Utility Monitoring: The insertion design is compatible with nominal diameters ranging from DN 80 to 1500 (3 to 60 inches). This makes it an ideal solution for main facility headers and large distribution ducts where flow trending is essential for energy management.
-
Hot-Tap Installation: One of the primary advantages of the t-mass B 150 is the ability to install or remove the sensor without interrupting the process. When used with appropriate mounting hardware, the sensor can be serviced while the pipe remains pressurized, ensuring zero downtime.
-
Direct Mass Flow Principle: Like the inline version, it measures mass flow directly. It does not require additional pressure or temperature sensors to provide accurate gas data, which simplifies the installation and reduces the total cost of the measurement point.
-
Low Flow Sensitivity: The thermal dispersion principle allows the t-mass B 150 to detect very low flow velocities and pressures. This is particularly useful for identifying leaks in large compressed air systems during non-production hours.
-
Data Transfer via Display: All customer-specific settings are stored within the display module. This allows for the rapid transfer of configurations between devices, ensuring that if a transmitter is replaced, the new unit can be commissioned almost instantly with the correct parameters.
-
Multivariable Trending: The device provides reliable flow trending and multivariable measurement, allowing operators to see not just the flow rate, but also integrated diagnostics and error monitoring for high plant availability.
