4.1.1Field Setup Wizard using Daniel MeterLink
Procedure
1.Use the Field Setup
2.Use General setup to configure the meter’s system units (U.S Customary or Metric units) volume units, flow rate time, low flow cutoff, contract hour and enable reverse flow. Select Next to continue to Frequency Outputs.
3.Configure Frequency output 1 and Frequency output 2 content (Daniel Liquid Ultrasonic Meters content is Uncorrected flow rate), flow direction, Channel B phase, maximum frequency output (Hertz) and Full scale volumetric flow rate. Select Next to continue to Meter Digital Outputs.
4.Select the Meter Digital Output parameters for Digital output 1A, Digital output 1B, Digital output 2A and Digital output 2B based on Frequency validity or flow direction.
if the output of the ultrasonic meter is reversed from what a flow computer is expecting, select Inverted Operation. This changes the digital output from a HIGH for a TRUE condition to output a LOW for a TRUE condition. Select Next to continue to Current Outputs.
5.Current Outputs are based on Uncorrected (Actual) flow rate content, flow direction (Forward, Reverse or Absolute) and Full scale volumetric flow rate used with output (20mA maximum). Alarm action parameters determines the state the output will drive during an alarm condition (High 20mA, Low - 4 mA, Hold last value, Very low - 3.5, Very high 20.5 mA or None). Select Next to continue to HART® Output(s).
6.HART® Output parameters include four Dynamic process variables (Primary, Secondary, Third and Fourth variable. The Primary variable is set to match the Content set for Current output 1. If a second current output is available, the Secondary variable is set to match the Content set for Current output 1, Identification and HART® units (volume units, Flow rate time units, Velocity units, Pressure and Temperature units). Select Next to continue to Temperature and Pressure.
7.Set the temperature and pressure scaling for analog inputs, enter fixed values, and set alarm limits for both.
8.Select Finish to write the configuration settings to the meter.
9.Save the meter configuration file and collect a Maintenance log.
10.Disconnect from the meter using the tool bar icon, 
, or the MeterDiconnect menu path and close the Daniel MeterLink application and prepare to seal the meter.
