Rosemount 8732
Upper Range Value This parameter set the flow rate in engineering units that corresponds to
100% flow. This parameter is configured in the Transducer Block.
The Upper Range Value can be set for both forward or reverse flow rates.
Flow in the forward direction is represented by positive values and flow in the
reverse direction is represented by negative values. The URV can be any
value from –43.3 ft/s to +43.3 ft/s (-13.2 m/s to +13.2 m/s), as long as it is at
least 1 ft/s (0.3 m/s) from the lower range value (LRV). The URV can be set to
a value less than the lower range value.
NOTE
Line size and density must be selected prior to configuration of URV and LRV.
Lower Range Value This parameter sets the flow rate in engineering units that corresponds to 0%
flow. This parameter is configured in the Transducer Block.
Set the lower range value (LRV) to change the size of the range (or span)
between the URV and LRV. Under normal circumstances, the LRV should be
set to a value near the minimum expected flow rate to maximize resolution.
The LRV must be between –43.3 ft/s to +43.3 ft/s (-13.2 m/s to +13.2 m/s).
NOTE
Line size and density must be selected prior to configuration of URV and LRV.
The minimum allowable span between the URV and LRV is 1 ft/s (0.3 m/s).
Do not set the LRV within 1 ft/s (0.3 m/s) of the URV. For example, if the URV
is set to 15.67 ft/s (4.8 m/s) and if the desired URV is greater than the LRV,
then the highest allowable LRV setting would be 14.67 ft/s (4.5 m/s). If the
desired URV is less than the LRV, then the lowest allowable LRV would be
16.67 ft/s (5.1 m/s).
Calibration Number The sensor calibration number is a 16-digit number used to identify sensors
calibrated at the Rosemount factory. The calibration number is also printed
inside the sensor terminal block or on the sensor name plate. The number
provides detailed calibration information to the Rosemount 8732. To function
properly within accuracy specifications, the number stored in the transmitter
must match the calibration number on the sensor exactly. This parameter is
configured in the Transducer Block.
NOTE
Sensors from manufacturers other than Rosemount Inc. can also be
calibrated at the Rosemount factory. Check the sensor for Rosemount
calibration tags to determine if a 16-digit sensor calibration number exists for
your sensor.
