EQUATION

/1: Temp. & pressure compensation for DP owmeter (ideal gas)

K2X2+A2

X0 = K1X1

K3X3+A3

where X0 : compensated ow (linear characteristic)

X1 : uncompensated ow (sq. root extraction available)

X2 : pressure

X3 : temperature

/2: Addition/subtraction

X0 = K0 {K1 (X1+A1) + K2 (X2+A2) + K3 (X3+A3)} + A0

/3: Multiplication

X0 = K0 (K1X1+A1) (K2X2+A2) (K3X3+A3) + A0

/4: Multiplication/division

K0 (K1X1+A1) (K2X2+A2)

X0 =

+ A0

(K3X3+A3)

/5: Multiplication/division

K0 (K1X1+A1)

X0 =

+ A0

(K2X2+A2) (K3X3+A3)

/6: Addition/multiplication

X0 = K0 (K1X1+K2X2+A1) (K3X3+A3) + A0

/7: Addition/division

K0 (K1X1+K2X2+A1)

X0 =

+ A0

(K3X3+A3)

/8: Addition/division

K0 (K1X1+A1)

X0 =

+ A0

(K2X2+K3X3+A2)

/9: Addition/multiplication

X0 = K0 (K1X1+A1) + K0 (K2X2+A2) (K3X3+A3) + A0

/10: Addition/division
