Manometer with diaphragm element for indication of pressure, under pressure or differential pressure of non aggressive gas. Thanks to the measuring principle, the device is irrespective of position and has an extremely high zero-point security with the smallest measuring ranges. Thereby, it is particularly suitable for air flow measurement according to the “Differential pressure” or “dynamic pressure” method with square-root characteristic. No negative pressure measurement possible.
