Overview of the technical advantages offered by the testo 6446 compressed air meter

The testo 6446 compressed air meter is also a transmitter, which converts the measured parameter into a standardized electrical signal. The transmitter can therefore be integrated into systems (e.g. compressed air systems), making it a key instrument in measuring and control technology. The testo 6446 compressed air meter also offers the following advantages:

• Ultimate flexibility with a variety of signal outputs: analog output, pulse output, 2 switching outputs. You will therefore be equipped for any kind of application, whether that is consumption measurement, consumption or leak monitoring or even flow measurement
• Integrated totalling function: the practical totaliser means that no additional analysis units are needed to calculate the total consumption
• Flexible mounting: with measuring block, pipe clamp or as a measurement fitting
• Ultimate accuracy: the compressed air meter is available in various sizes (notably larger pipe diameters are covered: DN65-250). At any size the inner diameter is precisely defined, enabling standard volume flow adjustment. You can therefore achieve a high degree of measuring accuracy – particularly in comparison with standard penetration probes, which deduce volume flow on the basis of measured flow and specified pipe diameter and are therefore prone to greater vulnerability to error
• Easy operation with a high degree of flexibility: parametrization of signal outputs, switching of physical units, signal delay, signal attenuation are all possible
• Measurement according to the calorimetric principle: no pressure loss during measurement
• Other advantages: no temperature compensation required, quick response time, robust sensor, optimized accuracy thanks to integrated inflow and outflow sections
