Distance Calculation

To calculate the transducer to material level (object) distance, the transmission medium (atmosphere) sound velocity (P653) is multiplied by the acoustic transmission to reception time period. The result (round trip distance) is divided by 2.

Distance = Sound Velocity x Time

2

The Reading Value displayed is the result of performing any additional modification to the calculated distance (Operation P001, Units P005, Volume Conversion, P050 to P054, Reading Value, P060 to P063.)

Sound Velocity

The sound velocity of the transmission medium is affected by the type, temperature, and vapour pressure of the gas or vapour present. As preset, the SITRANS LU01 assumes the vessel atmosphere is air at 20°C (68°F). Unless altered, the sound velocity used for the distance calculation is 344.1 m/s (1129 ft/s).
