| Compressed Air Flow Meters |
Measuring volumetric flow of air in the industries is a critical parameter, Compressed air counters or thermal mass flow meters are of immense help to these industries. These air-counters work on the principle of hot wire measurement technology and is not affected by process temperature and pressure. These air counters come in two versions-flow-cell and insertion version. Testo 644X family is widely known in industries like HVACs, Oil & Gas, Dryer manufacturers etc.

| Applications for compressed air meters |
| For a cost-oriented industrial company, compressed air consumption measurement offers the optimum possibility of investing in savings in compressed air, as the high costs of compressed air can only be reduced in stages if leaks are detected in compressed air systems and consumptions are assigned equitably to the respective consumers. |
| |
| Compressed air meters provide the ideal tool for: |
- Leak detection
- Allocation of consumption costs
- Peak load management
- Monitoring min./max. values
- Controlling consumption-dependent maintenance work
- Precise automatic metering of compressed air
