9. Specifications
Air flow meter, model A2G-25
Measuring element
Piezo measuring cell
Measuring range
0 ... 1,000, 0 ... 2,000, 0 ... 5,000, 0 ... 7,000 Pa
Accuracy
0 ... 1,000 Pa = pressure < 125 Pa = ±2 Pa + 1 %
Pressure > 125 Pa = ±1 Pa + 1 %
0 ... 2,000 Pa = pressure < 125 Pa = ±2 Pa + 1 %
Pressure > 125 Pa = ±1 Pa + 1 %
0 ... 5,000 Pa = pressure < 125 Pa = ±2 Pa + 1.5 %
Pressure > 125 Pa = ±1 Pa + 1.5 %
0 ... 7,000 Pa = pressure < 125 Pa = ±2 Pa + 1.5 %
Pressure > 125 Pa = ±1 Pa + 1.5 %
all data refer to the current measured value
