4.3 Equations in the TME 400

The TME 400 enables calculation of different values from the measured data and in
the data entered in the TME 400. For a better understanding, some variables and for-
mula in this chapter are presented in advance; other equations and definitions of pa-
rameters are found in the chapter 4.3.3. Coordinates in context.

Coordinates in context

In the following, the coordinates which can be addressed with the TME 400-VM and
TME 400-VMF turbine meters are shown. In the tables, the parameters which can be
addressed with the TME 400-VM are shown in light blue and the values which are
additionally available with the version for custody-transfer applications, TME 400-
VMF, are shown in orange.
