Dry calibration

The meter uses a third-order polynomial for dry calibration as shown in Equation 6-8. Click the Advanced View button to display the zero flow calibration polynomial coefficients. Regardless of what flow calibration method is selected, the zero flow calibration polynomial coefficients will be applied first.

Modification of dry calibration parameters is not recommended. The dry calibration parameters should not be modified unless directed by Daniel personnel.

The meter provides separate dry calibration coefficients for each flow direction as listed in the table below.
