March 2004
General Specifications
The general specifications for the Model UTX878 flow transmitter
are divided into the following categories:
Hardware Configuration
Channel Options:
Standard: 1-Channel/Path
Optional: 2-Channel/Path (for 2-path averaging).
Enclosure:
Epoxy-coated aluminum, weatherproof, NEMA 4X, IP67
Dimensions:
Weight 3.9 lb (2 kg)
Size (h x w x d) 8.8 x 8.2 x 3.6 in. (220 x 210 x 90 mm)
Environmental
Ambient Operating Temperature:
-4° to +140°F (-20° to +60°C)
Storage Temperature:
-40° to +158°F (-20° to +70°C)
Measurement
Parameters
Volumetric flow, totalized flow, and flow velocity
Keypad
Six-button external keypad
Flow Accuracy
(% of Reading)
Pipe Diameter (ID) > 6 in. (150 mm):
±1% to 2% of reading typical
Pipe Diameter (ID) < 6 in. (150 mm):
±2% to 5% of reading typical
Note:
Accuracy depends on pipe size and whether measurement is
one-path or two-path. Accuracy to ±0.5% of reading may be
achievable with process calibration.
Range
-40 to +40 ft/s (-12.2 to +12.2 m/s)
Rangeability
400:1
Repeatability
±0.1% to 3% of reading
Note: Specifications assume a fully developed flow profile, with a
straight run of pipe 10 diameters upstream and 5 diameters
downstream, and flow velocity greater than 1 ft/s.
Fluid Types
Acoustically conductive fluids, including most clean liquids and
many with entrained solids or gas bubbles.
