Configuration
March 2023
Verify configuration parameters with the local operator
interface (LOI)
Procedure
1. Press either configuration button to activate the LOI.
2. Select View Config.
2.5.3 Setting pressure units
The pressure unit command sets the unit of measure for the reported pressure.
The procedure is the same for other variables:
• Flow
• Totalizer
• Level
• Volume
• Module Temperature
Select your desired variable and then follow the procedure the procedure below using the
desired variable in place of Pressure.
Set pressure units with a communication device
Procedure
Go to Device Settings → Output → Pressure → Setup.
Set pressure units with the local operator interface (LOI)
Procedure
1. Click either button to activate the LOI.
2. Select Units.
2.5.4 Setting transmitter output (transfer function)
The transmitter has two output settings: Linear and Square root.
As shown in
proportional to flow and includes a fixed Low Flow Cut-off at four percent and a Low Flow
Cut-in of five percent of the square root analog output range.
Emerson recommends using application-specific configuration to configure differential
pressure (DP) flow applications. Refer to
instructions. When flow rate is assigned to the primary variable, the transfer function
will be set to linear in the communication device and cannot be changed to square root.
The flow rate variable is automatically set to a square root relationship with respect to
pressure.
