Upper Range Value

Lower Range Value

Calibration Number

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.

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).

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.
