Figure A-1. Rosemount 8800 Vortex Flowmeter Ambient/Process Temperature Limits
Shows combinations of ambient and process temperatures needed
Note
The indicated limits are for horizontal pipe and vertical meter position, with meter and pipe
insulated with three inches of ceramic fiber insulation.
Pipe length requirements
The vortex meter may be installed with a minimum of ten diameters (D) of straight pipe
length upstream and five diameters (D) of straight pipe length downstream.
Rated Accuracy is based on the number of pipe diameter from an upstream disturbance. No
K-factor correction is required if the meter is installed with 35D upstream and 5D
downstream. The value of the K-factor may shift up to 0.5% when the upstream straight
pipe length is between 10D and 35D. Please see Technical Data Sheet (00816-0100-3250)
on Installation Effects for optional K-factor corrections. This effect can be corrected in the
electronics.
Tagging
The flowmeter will be tagged at no charge, according to customer requirements. All tags
are stainless steel. The standard tag is permanently attached to the flowmeter. Character
height is 1/16-in. (1,6 mm). A wired-on tag is available on request. Wire on tags can contain
five lines with up to 28 characters per line.
Flow calibration information
Flowmeter calibration and configuration information is provided with every flowmeter. For
a certified copy of flow calibration data, Option Q4 must be ordered in the model number.
