Rosemount 8800D
Pressure and Temperature Transmitter Location
When using pressure and temperature transmitters in conjunction with the
Rosemount 8800D for compensated mass flows, install the transmitter(s)
downstream of the Vortex Flowmeter. See Figure 2-4.
Wetted Material
Selection
Ensure that the process fluid is compatible with the meter body wetted
materials when specifying the Rosemount 8800D. Corrosion will shorten the
life of the meter body. Consult recognized sources of corrosion data or contact
your Rosemount Sales Representative for more information.
NOTE
For accurate results perform a Positive Material Identification (PMI) test on a
machined surface.
Environmental
Considerations
Avoid excessive heat and vibration to ensure maximum flowmeter life. Typical
problem areas include high-vibration lines with integrally mounted electronics,
warm-climate installations in direct sunlight, and outdoor installations in cold
climates.
Although the signal conditioning functions reduce susceptibility to extraneous
noise, some environments are more suitable than others. Avoid placing the
flowmeter or its wiring close to devices that produce high intensity
electromagnetic and electrostatic fields. Such devices include electric welding
equipment, large electric motors and transformers, and communication
transmitters.
HAZARDOUS
LOCATIONS
The Rosemount 8800D has an explosion-proof housing and circuitry suitable
for intrinsically safe and non-incendive operation. Individual transmitters are
clearly marked with a tag indicating the certifications they carry. See
Appendix B: Approval Information for specific approval categories.
