FUNCTION EQUATIONS:
SVA(out) = K[SQRT[(((H
2
-L
2
)E/100) + L
2
)X((P + 14.7)/(T + 460))]]
Where: E = Transmitter input, 0 to 100 percent
L = Low engineering units conversion factor
H = High engineering units conversion factor
P = Gauge pressure of gas in psig
T = Temperature of gas in
0
F
K = SQRT[(Tc + 460)/(Pc + 14.7)]
Where: Tc = Temperature in
0
F of gas at standard operating conditions.
Pc = Gauge pressure in psig of the gas at standard operating conditions.
Note that Tc and Pc are the values used in the original orifice calculations.
If -2 percent <= transmitter input <= 102 percent
Then SVD(out) = 0
Else
Then SVD(out) = 1
