Model 8712C/U/H Magnetic Flowmeter Transmitters
4-8
Calibration Number
The tube calibration number is a 16-digit number used to identify
flowtubes calibrated at the Rosemount factory. The number provides
detailed calibration information to the Model 8712C/U/H. The
calibration number is also printed inside the flowtube terminal
block. To function properly within accuracy specifications, the
number displayed on the transmitter must match the calibration
number exactly.
NOTE
Flowtubes from manufacturers other than Rosemount Inc. can also be
calibrated at the Rosemount factory. Check the tube for Rosemount
calibration tags to determine if a 16-digit tube calibration number
exists for your flowtube.
NOTE
Be sure the calibration number reflects a calibration to a Model 8712C.
If the number reflects calibration to a Model 8712, accuracy of the
system may be compromised.
If your flowtube is not a Rosemount flowtube and was not calibrated at
the Rosemount factory, see Universal Auto Trim
(Model 8712U Only) on page 4-5
If your flowtube is imprinted with an eight-digit number or a k-factor,
check in the flowtube wiring compartment for the sixteen-digit
calibration number. If there is no serial number, contact the factory for
a proper conversion.
Damping
Damping allows selection of a response time, in seconds, to a step
change in flow rate. It is most often used to smooth fluctuations
in output.
