SPECIFICATIONS
Functional Specifications
Flowtube Compatibility
Compatible with Rosemount Model 8705 or Model 8711 Flowtubes.
Flow Rate Range
Capable of processing signals from fluids that are traveling between
0.04 and 30 ft/s (0.01 to 10 m/s) for both forward and reverse flow in all
flowtube sizes. Full scale continuously adjustable between
–30 and 30 ft/s (–10 to +10 m/s).
Fluid Conductivity
Fluid must have conductivity of at least
5 microsiemen/cm.
Power Supply
90–250 V ac 50–60 Hz.
15– 50 V dc.
Power Consumption
10 watts maximum.
Ambient Temperature Limits
Operating
–40 to 165 °F (–40 to 74 °C).
Storage
–40 to 185 °F (–40 to 85 °C).
Output Signals
4–20 mA, switch-selectable as internally or externally powered;
0 to 1000 ohm load.
On the digital output terminals, a scalable frequency output is
available, 0 to 1000 Hz; transistor switch closure up to 5.75 W,
externally powered, 5 to 24 V ac or dc.
HART Communications, digital flow signal, superimposed on 4–20 mA
signal, available for control system interface. 250 ohms required for
HART Communications.
Analog Output Adjustment
Engineering units, lower and upper range values are user-selected.
Output automatically scaled to provide 4 mA at selected lower range
value, 20 mA at the selected upper range value. Full scale continuously
adjustable between –30 and +30 ft/s (–10 to +10 m/s), 1 ft/s (0.3 m/s)
minimum span. 4 mA also continuously adjustable.
Scalable Frequency Adjustment
Pulse Value
Value of one pulse can be set to equal desired volume in selected
engineering units.
Pulse Width
Adjustable from 0.5 to 100 ms. Local Operator Interface option
automatically calculates and displays maximum allowable
output frequency.
