Endress+Hauser’s number one choice for measuring compressed air and technical gases in the bulk solids processing industry is the t-mass 150 thermal mass flowmeter, specially designed for use in compressed air and supply networks.
Much of the energy used when producing compressed air is lost unnecessarily, whether through leaks excessive system pressure or waste heat from the compressor.
Compressed air networks with leak rates of 30% and more are found in many plants around the world. Quite startling, considering that energy conservation and reduction is top of nearly every company’s agenda. For this reason, more and more attention is being focused on compressed air and supply networks. A detailed insight into a system is needed to locate and minimise leaks in the network. By using several low-cost measuring systems in one line instead of one more accurate and more expensive main measurement, users can get a far clearer picture of their compressed air network.
Reliable leakage-fixing
While small leaks in the overall gas flow go unnoticed when a primary-measurement system is used, measurements on a line reliably indicate an increase in the measured value. Experience shows that 3-6 line measurements are typically required for one primary measurement. Here, reproducibility is often more important than absolute accuracy in order to achieve long-term savings in the extensive distribution networks. In addition to minimum pressure loss, reliable operation is also a decisive factor for successful instrument deployment. This is because the measuring point, once commissioned, can often only be accessed with a great deal of effort.
The ‘small gas engine’ for flexibility
The device is supplied completely preconfigured to a client’s requirements. The t-mass comes with an integrated ‘gas engine’. At the device, users can directly select air, argon, nitrogen or CO, as the gas. By using the ‘engine’ no recalibration on-site is required. All the gas parameters are calculated in the device based on the current operating state. Local operation displays plain text in all common languages.
The modular design allows the instrument to be optimally adjusted to suit the application.
What is more, users can also benefit from the attractive procurement and low operating costs of t-mass 150. The robust housing construction withstands the heavy-duty ambient conditions in the bulk solids processing industry, while the solid sensor design is maintenance-free and has no moving parts.
Another advantage of the device is that it outputs the gas corrected volume directly. In this way it is possible to directly compare all the measuring paints without the need for additional pressure and temperature compensation.
