What is the difference between the nonlinearity calculated by TPM method and BFSL method?

The basic accuracy specified by manufacturers of pressure and level transmitters in their datasheets includes nonlinearity, hysteresis and repeatability. Very often, next to nonlinearity data you see "BFSL" and / or "TPM". These are two different approaches to calculating nonlinearity...
