4. Verify Analog Input (AI) Block.
Note
Scaling should not be repeated in the AI Block. To ensure no additional scaling is being done
on the Al Block, set the lower values in steps
a. In the Basic Setup >> Units >> Process Value Scale (Analog Input Block) field, enter upper
b. In the Basic Setup >> Units >> Output Signal (Analog Input Block) field, enter upper and

Detailed setup tasks

The following tasks explain how to configure the Rosemount 2051 for Flow or Level
measurement and how to configure additional parameters found in the device.
2.6.1

Flow configuration

LOI
To configure the Rosemount 2051 for flow measurement with the LOI, select UNITS >>
FLOW. When configuring flow units, the following parameters are set:
Measurement type: Flow

Linearization (Transducer Block): Square Root

During unit configuration, the user defines scaling, units and low flow cutoff per the
application requirements. See
menu for further scaling help.
Note
The LOI assumes a zero based scaling (minimum pressure = minimum flow = zero) for Flow
applications in order to improve configuration efficiency. Class 2 Masters can be used if
non-zero based scaling is required. Low Flow Cutoff has a default value of 5.0%. Low Flow
Cutoff can be set to 0% if required.
Class 2 Master
To configure the transmitter for a flow application, use the flow output in the Transducer
Block. See
Configuration
