8. You must now determine a SCALING FACTOR “m” according to the equation
m = V x E x R
where
—“V” is the VOLUME (or MASS) EQUIVALENT for one pulse of the flowmeter, as
given in the calibration data supplied with the flowmeter
—“E” is the
conversion factor for changing the volume or mass units given in the
flowmeter datasheet to the units desired for the final volume or mass mea-
surement; e.g., if the calibration data supplied with the flowmeter uses
cubic
feet
and you want the final measurement to be in cubic meters, E = 0.028
(m

)
— “R” is the “range factor”—in this case, the
count increment—to which Channel
No. y has been set in Step 7, above (R = 1, 10, or 100).
9. Now set up a CALCULATE PSEUDOCHANNEL No. “z” to represent total volume or
mass. Turn ON the system EEPROM Switch and enter a command of
CLC z = m(CHN y) + 0 [CR]
where “m” is the SCALING FACTOR calculated in Step 8. NOTE: Additional CAL-
CULATE PSEUDOCHANNELS can easily be set up to produce temperature-
corrected
mass flow (see Manual Section 2.J, and contact the factory for detailed
instructions).
