7.11.1 Method of Flow Calculation
When using the SITRANS LUT400 in a flow application, the Method of Flow Calculation
(2.15.3.1.) (Page 231) must be selected. There are two possible methods for calculating flow
with the SITRANS LUT400: absolute or ratiometric, and different information must be
entered for the device to carry out the calculation. For more details, and an example, see
Method of Flow Calculation (Page 302).
