A3.3.1 Computing Equations
This subsection shows computing equations used in the computation section:
1) Flow rate compensation (linear)
func = PV x f
f = (t_1/t_2)
2) Flow rate compensation (square root)
func = PV x f
f = sqrt(t_1/t_2/t_3)
3) Flow rate compensation (approximate formula)
func = PV x f
f = sqrt(t_1 x t_2 x t_3 x t_3)
4) Calorie calculation
func = PV x f
f = (t_1−t_2)
5) Multiplication and division
func = PV x f
f = ((t_1/t_2) + t_3)
6) Average calculation
func = (PV + t_1 + t_2 + t_3)/N
where N: number of inputs
7) Summation
func = PV + t_1 + t_2 + t_3
8) Polynomial computation
func = PV + t_1

+ t_2
3
+ t_3

9) HTG level compensation
func = (PV−t_1)/(PV−t_2)
