MASFLW MASFLW

INSTRUCTION NAME: MASFLW (mass flow - ideal gas)

DESCRIPTION: This instruction incorporates the temperature and pressure of a gas, at flowing

conditions, into the linearization of an analog flow input. The input is a signal from a non-linearized

flow transmitter, and the SVA output is in engineering units. The MASFLW function differs from the

AINSQR function in that the AINSQR function assumes constant pressure and temperature,

whereas the MASFLW function handles pressure and temperature as variables.

The SVD output serves as an out of range indication. When the input is between -2 and 102

percent of span, the SVD output is 0. If the input is outside of this range, the SVD output is 1.

OPERAND DESCRIPTIONS:

Pressure - The name of the general register or analog loadable function where the pressure (P) in

psig of the flow system is stored.

Temperature - The name of the general register or analog loadable function where the

temperature (T) in

F of the flow system is stored.
