Finds the Density from calibration constants and a frequency signal. The density is then corrected for pressure and temperature effects. In addition a velocity of sound correction can be applied for Liquid Petroleum Gas (LPG).
Constants used are from the Solartron liquid density transducer calibration certificate.
