Reverse Flow
Detects and reports reverse flow
Software Lockout
A write-lock switch and software lockout are provided in the resource function

Turn-on Time
5 minutes to rated accuracy from power up; 10 seconds from power

Start-up Time
50 ms from zero flow.
Low Flow Cutoff
Adjustable between 0.01 and 38.37 ft/s (0.003 and 11.7 m/s). Below selected
value, output is driven to the zero flow rate signal level.
Overrange Capability
Signal output will remain linear until 110% of upper range value or 44 ft/s (13
m/s). The signal output will remain constant above these values. Out of range
message displayed on local display and field communicator.
Damping
Adjustable between 0 and 256 seconds.
Sensor Compensation
Rosemount sensors are flow-calibrated and assigned a calibration factor at
the factory. The calibration factor is entered into the transmitter, enabling
interchangeability of sensors without calculations or a compromise in
standard accuracy.
