Remarks

● Unless otherwise specified, this product is calibrated under the following conditions: nitrogen, 25°C, 2.5 bar differential pressure (3.5 barA inlet, 1 barA outlet), horizontal placement.

● It is recommended to install a straight pipe section of appropriate size at the inlet, otherwise it may cause deviation in accuracy.

● It is recommended to match the largest possible connectors at the inlet and outlet to avoid causing additional pressure loss.

1. The shown range is the selectable range for nitrogen.

2. %F.S. refers to the percentage of error to the full scale.

3. %S.P. refers to the percentage of error to the setpoint.

4. Response time refers to the time required to reach within ±2% of the setpoint.

5. Operating pressure refers to the differential pressure between the inlet and outlet.
