Note: 1. At standard atmospheric pressure (1013.25 hPa).

2. Dry gas must not contain large particles, e.g., dust, oil or mist.

3. Type D6F-PH is based on thermal flow principle. Air flow is needed to measure the differential pressure. Typical characteristic of air flow

by differential pressure is shown in the “Engineering Data” section.

4. The zero point tolerance and span tolerance are independent uncertainties and add according to the principles of error propagation.
