Rosemount 8800D
Remote (Optional)
Electronics may be mounted remote from the meter body. Interconnecting coaxial cable
available in nonadjustable 10, 20, and 30 ft (3,0, 6,1, and 9,1 m) lengths. Consult factory for
non-standard lengths up to 75 ft (22,9 m). Remote mounting hardware includes a pipe mount
bracket with one u-bolt.
Temperature Limitations for Integral Mounting
The maximum process temperature for integral mount electronics is dependent on the
ambient temperature where the meter is installed. The electronics must not exceed 185°F
(85°C). The following is for reference, please note that the pipe was insulated with 3 inches of
ceramic fiber insulator.
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 35 D upstream and 10 D 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.
