3. For a Version 3.0, 3.5, and 3.6 RFT9739, ensure the mass-flow
meter factor is
1.0000
. To check the meter factor, open the Configure
menu, then choose Meter Factors to open the Meter Factors dialog
box. Change the mass-flow meter to 1.0000 if any other value is
displayed.
4. Enter the flow calibration factor (eight digits and two decimal points)
into the FlowCal text box.
Enter the flow calibration factor from the sensor serial number tag
— this is the preferred method;
or
Enter the flow calibration factor from the calibration certificate that
was shipped with the sensor.
5. Zero the flowmeter. The zeroing procedure is described in
Section 14.2
, page 133.
6. Open the Applications menu, then choose Totalizer Control or
IFT9701/IFT9703 Totalizer Control (for an IFT9701 or IFT9703).
Choose Reset to reset the internal totalizer to zero.
7. Run three batches of fluid, resetting the scale and totalizer between
batches. For each batch, record the weights indicated by the scale
and the totalizer.
8. Divide
Total Weight
scale
by
Total Weight
flowmeter
. This is the mass-flow
meter factor. Record the meter factor.
9. For a Version 3.0, 3.5, or 3.6 RFT9739, the mass-flow meter factor
may be entered into the transmitter as an alternative to completing
this procedure. The meter factor adjusts the flowmeter measurement
without modifying the flow calibration factor.
To enter the meter factor, open the Configure menu, then choose
Meter Factors to open the Meter Factors dialog box. After
entering the meter factor, it is not necessary to perform steps 10
through 12 of this procedure.
For information on meter factors, see
Chapter 13.
