Rosemount 8600 Vortex Flow Meter
Reference Manual
May 2019
Installation
00809-0100-4860, Rev BF
Upstream/Downstream piping
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 5 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 for
using the Installation Effect Correction Factor (See page 50).
Pressure and temperature transmitter location
When using pressure and temperature transmitters in conjunction with the Rosemount
8600D for compensated mass flows, install the transmitter(s) downstream of the Vortex
Flowmeter. See Figure 3-4.

Note
The MTA option can be purchased for an integral temperature measurement and mass flow
temperature compensation for saturated steam only.
A. Pressure transmitter
B. Four straight pipe diameters downstream
C. Temperature transmitter
