In the system and method of the present invention, the temperature and pressure upstream of the pyrolysis reactor are measured by an adiabatic restriction in the inlet manifold of the parallel tube assembly to provide an absolute upstream temperature and upstream pressure. The temperature downstream of the pyrolysis reactor is also measured in accordance with the adiabatic limiting to provide an absolute downstream temperature. The downstream pressure is then determined by multiplying the absolute upstream pressure by the downstream temperature raised to the power of k/k-1 of the quotient of the upstream temperature, where k is the ratio of the specific heat of the fluid at constant pressure (Cp) to the specific heat of the fluid at constant volume (Cv).)
