EQUATION
/1: Temperature compensation for DP flowmeter (ideal gas)
K1X1
X0 =
K2X2+A2
where X0 : compensated flow (linear characteristic)
X1 : uncompensated flow (square root extraction available)
X2 : temperature
/2: Pressure compensation for DP flowmeter (ideal gas)
X0 = K1X1 K2X2+A2
where X0 : compensated flow (linear characteristic)
X1 : uncompensated flow (square root extraction available)
X2 : pressure
MODEL: 18JF–[1]66–R[2]
/3: Addition/subtraction
ORDERING INFORMATION
• Code number: 18JF-[1]66-R[2]
X0 = K0 {K1 (X1+A1) + K2 (X2+A2)} + A0
/4: Multiplication
Specify a code from below for each of [1] and [2].
(e.g. 18JF-666-R/3)
X0 = K0 (K1X1+A1) (K2X2+A2) + A0
/5:Division
Use Ordering Information Sheet (No. ESU-1980). Default
setting will be used if not otherwise specified.
