Rosemount Model 8732C Integral Mount Magnetic Flowmeter System
7-4
Performance
Specifications
(System specifications at reference conditions with frequency output and flowtube in new condition.)
Accuracy (with Model 8712C, Model 8712U or Model 8732C)
±0.5% of rate from 1 to 30 ft/s (0.3 to 10 m/s). Includes combined effects of
linearity, hysteresis, repeatability, and calibration uncertainty. Accuracy is
±0.005 ft/s (±0.0015 m/s) from low-flow cutoff to 1.0 ft/s (0.3 m/s).
Vibration Effect
Meets IEC 770 Pipeline Installation Conditions.
Mounting Position Effect
None when installed to ensure flowtube remains full.
Physical
Specifications
Non-Wetted Materials
Flow Tube
AISI Type 304 SST.
Flanges
Carbon steel or AISI Type 304 SST.
Housing
Welded steel.
Paint
Polyurethane.
Process Wetted Materials
Lining
PTFE Teflon, ETFE Tefzel, polyurethane, neoprene, or natural rubber.
Electrodes
316L SST, Hastelloy C-276, tantalum, platinum-10% iridium, titanium.
Process Connections
AISI Type 304 SST – includes ANSI Class 150 flange to Tri-Clover Tri-Clamp
3-A quick-disconnect ferrule.
Process Connections
ANSI Class 150 or ANSI Class 300
½ through 24 inch.
AWWA Class 125
30- and 36-inch.
DIN PN 10, 16, 25, and 40
PN40 Standard Flange for 15–80 mm.
PN16 Standard Flange for 100–150 mm.
PN10 Standard Flange for 200–600 mm.
Electrical Connections
Two ¾–14 NPT connections are provided in the terminal enclosure for
electrical wiring.
Grounding Rings
Grounding rings are installed between the flange and the tube face on both ends
of the flowtube. They have an I.D. slightly larger than the flowtube I.D. and an
external tab to attach ground wiring. Grounding rings are available in 316L
stainless steel, Hastelloy C-276, titanium, and tantalum.
Grounding Electrode
A grounding electrode is installed similarly to the measurement electrodes
through the flowtube lining. It is available in 316L stainless steel,
Hastelloy C-276, titanium, tantalum or platinum.
Flowtube Dimensions
See Tables 7-3 and 7-4; Figures 7-1 and 7-2.
