AR (Arithmetic) Function Block
Functions Supported
The following function types are supported:
Flow compensation, linear
Used for density compensation of volume flow.
func = f * PV
Flow compensation, square root
Usually, IN_1 is pressure, IN_2 temperature, and IN_3 is the compressibility factor Z.
func = f * PV
f = sqrt (t_1 / t_2 / t_3) [limited]
Flow compensation, approximate
Both IN_2 and IN_3 would be connected to the same temperature.
func = f * PV
f = sqrt (t_1 * t_2 * t_3 * t_3) [limited]
BTU flow
Where IN_1 is inlet temperature, and IN_2 the outlet temperature
func = f * PV
f = (t_1 - t_2) [limited]
Traditional Multiply Divide
func = f * PV
f = (t_1 / t_2) + t_3 [limited]
Average
func = (PV + t_1 + t_2 + t_3) / f
f = number of inputs used in computation (unusable inputs are not used).
Traditional Summer
func = PV + t_1 + t_2 + t_3
Fourth order polynomial
All inputs except IN_LO (not used) are linked together.
func = PV + t_1 ** 2 + t_2 ** 3 + t_3 ** 4
