Configure process measurement Restriction If the API referral application is enabled, you cannot change the density measurement unit here. The density measurement unit is controlled by the API table selection. Procedure Set Density Measurement Unit to the option you want to use. The default setting for Density Measurement Unit is g/cm3 (grams per cubic centimeter).
Value specifies the time period (in seconds) over which the transmitter will spread changes in the process variable. At the end of the interval, the internal value will reflect 63% of the change in the actual measured value. Micro Motion ® Fork Density Meters (FDM)
Configure process measurement Density damping affects all process variables that are calculated from line density. Procedure Set Density Damping to the value you want to use. The default value is 0 seconds. The range is 0 to 60 seconds. Interaction between Density Damping and Added Damping When the mA output is configured to report density, both Density Damping and Added Damping are applied to the reported density value.
The default value for Two-Phase Flow Timeout is 0.0 seconds, meaning that the alert will be posted immediately. The range is 0.0 to 60.0 seconds. Micro Motion ® Fork Density Meters (FDM)
Configure process measurement Detecting and reporting two-phase flow Two-phase flow (gas in a liquid process or liquid in a gas process) can cause a variety of process control issues. By configuring the two-phase flow parameters appropriately for your application, you can detect process conditions that require correction. To decrease the occurrence of two-phase flow alerts, lower Two-Phase Flow Low Limit or raise Two-Phase Flow High Limit.

If you are using a HART/Bell 202 connection, the HART signal over the primary mA output affects the mA reading. Disconnect the wiring between ProLink III and the transmitter terminals when reading the primary mA output at the receiving device. Reconnect to continue the trim. Micro Motion ® Fork Density Meters (FDM)
Troubleshooting Check the trim results. If any trim result is less than −200 microamps or greater than +200 microamps, contact Micro Motion customer service. 10.15.2 Trim mA outputs using the Field Communicator Trimming the mA output establishes a common measurement range between the transmitter and the device that receives the mA output.

Troubleshooting 10.17 Check Lower Range Value and Upper Range Value If the process variable assigned to the mA output falls below the configured Lower Range Value (LRV) or rises above the configured Upper Range Value (URV), the meter will post a saturation alert (A100 or A113), then perform the configured fault action.
You can reduce the occurrence of two-phase flow alerts by setting Two-Phase Flow Low Limit to a lower value, Two-Phase Flow High Limit to a higher value, or Two-Phase Flow Timeout to a higher value. Related information Configure two‐phase flow parameters Micro Motion ® Fork Density Meters (FDM)

• Connect with ProLink III Basic information about ProLink III ProLink III is a configuration and service tool available from Micro Motion. It runs on a Windows platform and provides complete access to transmitter functions and data. Version requirements The following version of ProLink III is required: v2.4 or later.
These features are documented in the ProLink III manual. They are not documented in the current manual. ProLink III messages As you use ProLink III with a Micro Motion transmitter, you will see a number of messages and notes. This manual does not document all of these messages and notes. Important The user is responsible for responding to messages and notes and complying with all safety messages.
Using ProLink III with the transmitter • Modbus connections, including service port connections, are typically faster than HART connections. • When you are using a HART connection, ProLink III will not allow you to open more than one window at a time. This is done to manage network traffic and optimize speed.
