5.1.2 Wet calibration
The Daniel 3410 Series Gas Ultrasonic Flow Meter meter offers three selections for wet
calibration: 12-point piece-wise linearization, a third-order polynomial, or none. The wet
calibration method is selected via the
CalMethod data point with “None” being the default
value. The wet calibration gas flow velocity is calculated from the dry calibration gas flow
velocity as shown in Equation 5-2.

1. Choose a Flow Calibration Method:
• Polynomial
• Piece-wise linear
• None (If set to
None then the wet calibration has the same value as the dry
calibration.)
