Analog Range Values (Re-scaling the meter) The Analog Range settings can be read and set from the “Analog Range Values” dialog box. To bring up this box, click the “Configure Meter” pull-down menu on the Main screen and then select “Analog Range Values”.
Primary Variable (PV) The primary variable can be read and set from the “Primary Variable” dialog box. To bring up this box, click the “Configure Meter” pull-down menu on the Main screen and then select “Primary Variable”. The primary variable is the value that controls the analog output current when the meter is inservice. When the meter is in edit mode, the primary variable (PV) will change, but the analog output current will not be changed.
HART Interface There are many HART related fields that can be viewed and set using the “HART Interface” dialog box. To bring up this box, click the “Configure Meter” pull-down menu on the Main screen and then select “HART Interface”. When this window is opened, the current field values are read from the meter and displayed in the window.
Number of Preambles - This field allows the user to change the number in the preambles at the beginning of HART messages transmitted by the meter. A preamble is a special character that is transmitted at the beginning of HART messages. The purpose of preambles is to prepare the receiving HART circuitry to receive the remainder of the message. The typical number of the preambles is five. The valid range of preambles is 3 to 15.
Process Temperature The Process Temperature settings are accessed through the “Process Temperature” dialog box. To bring up this box, click the “Configure Meter” pull-down menu on the Main screen and then select “Process Temperature”.
Integrated RTD - If the meter is supplied with an integrated RTD, it is typically the best choice for the “Process Temperature Source”. The integrated RTD is embedded in the meter housing and can provide real-time process temperature information. With real-time temperature information, the meter can compensate for mass flow and standard flow measurements when the temperature changes. If the process temperature displays 999F when using the integrated RTD, the RTD has failed.
Process Pressure The Process Pressure settings are accessed through the “Process Pressure” dialog box. To bring up this box, click the “Configure Meter” pull-down menu on the Main screen and then select “Process Pressure”. Process Pressure Process Pressure: 0 Process Pressure Units: psi Process Pressure Source: Analog Input - Absolute Analog Input - Gauge User Defined Steam Table Atmospheric Pressure: 14.
Process Pressure Source - There are four different sources that can be selected for the process pressure: • • • • An absolute pressure analog input A gauge pressure analog input A user defined pressure value The steam table. NOTE: The analog inputs selections are not available on “non-compensating” models. Analog Input (Absolute) - This pressure source allows the user to input absolute pressure information into the meter using the meter’s analog input.
User Defined Pressure - This field allows the user to enter a constant process pressure. However, this pressure is only used when “User Defined” is selected as the process pressure source. The unit for this field is PSIG. Pressure Reading for 4 mA Analog Input - This field is used to specify the lower range of the analog pressure input. Enter the pressure value that is associated with 4 mA on the analog pressure input.
The main purpose of this window is to allow the user to specify the source that the meter should use for density and viscosity information. This information is required by the meter in order to accurately calculate flow. There are three sources for density and viscosity information; a property table, user defined density and viscosity values, and the steam property table.
Property Table Version Number - This field displays the version number of the loaded property table. Process Density - This field displays the process density. If “Property Table” is selected as the “Density and Viscosity Source”, then the meter will calculate this value from the property table based on the current process temperature and pressure. If “User Defined” is selected as the “Density and Viscosity Source”, this field will be equal to the “User Defined Density” field.
LCD Display Mode The display mode can be accessed through the “LCD Display” dialog box. To bring up this box, click the “Configure Meter” pull-down menu on the Main screen and then select “LCD Display”. This dialog box is only available to models that have an LCD display.
Alternating PV & Totalizer - This selection causes the LCD to alternate between the PV and totalizer. This selection is only valid when the primary variable is set to “Volumetric”, “Mass”, or “Standard” flow. If alternating PV & totalizer is being displayed on the LCD and the PV selection is changed to something other than “Volumetric”, “Mass”, or “Standard” flow, then the LCD mode will automatically be changed to “-Primary Variable” (PV). The totalizer is started and stopped by the “Totalizer” dialog box.
Output Current and Percent of Range - This selection causes the analog output current and the percent of range values to be output during burst mode. Command number 2 of the Racine HART Message Specification defines the format of this message. Output Current and Four Dynamic Variables - This selection causes the analog output current, the primary variable (PV), the vortex shedding frequency, the process temperature, and the process pressure to be output during burst mode.
Password Protection Password Protection Enabled Password: Password Verification: Read Write Close To password protect the meter, click the “Password Protection Enabled” box and enter a password into the “Password” box. The password must be repeated in the “Password Verification” box before the “Write” button is clicked. There is a “Password Protection” status indicator on the main screen. The indicator is green when password protection is enabled and black when password protection is disabled.
The active alarm current setting is read from the meter and displayed when this dialog box is opened. To change the setting, click the desired selection and then click the Write button. Alarm Selection Alarm Current Level: High (21.75 mA) Low (3.75 mA) Read Write Close NOTE: Save the changes to EEPROM and put the meter in-service after making changes. Pipe ID The internal diameter of the pipe or the pipe ID can be read from the “Pipe ID” dialog box.
For shedding frequencies below the selected cut-off, the output value will be set to 0 flow. This feature is helpful at low flows where noise in the environment can cause the flow to appear erratic. NOTE: Save the changes to EEPROM and put the meter in-service after making changes. K-Factor The K-Factor can be read and set from the “K-Factor” dialog box. To bring up this box, click the “Configure Meter” pull-down menu on the Main screen and then select “K-Factor”.
Totalizer Settings Totalizer Enabled Multiplier: 0.001 Roll Over Value: 1000000 Custom Unit: Read Write Close The value of the totalizer is stored in the meter’s non-volatile memory once each minute and whenever the totalizer is stopped or reset. Therefore, the totalized value continues to increase even after a power outage. There is, however, the possibility to lose the last minutes worth of totalized flow since the totalizer value is only saved to non-volatile memory once each minute.
Totalizer Enabled - The totalizer is running when this box is checked. The totalizer can also be started and stopped by checking and un-checking this box. However, the totalizer value is set to zero whenever the totalizer is configured using the “Totalizer Settings” dialog box. For normal operation, use the controls provided by the totalizer dialog box under the “Tools” menu to start, stop, and reset the totalizer.

Power Up - The settings of the totalizer are stored in non-volatile memory. Therefore, if the totalizer is running (totalizing) when the meter losses power, it will begin to run again when power is restored. The value of the totalizer is saved in non-volatile memory once every minute or whenever the totalizer is stopped or zeroed. When the totalizer is running and power is lost, the totalizer can loose a maximum of one minute’s data.
The “Property Table” dialog box is a tool used to load property tables into the meter. This dialog box can also be used to export a property table, but that operation is seldom needed. Typically, property tables are loaded into the meter at the factory and do not need to be changed. Click the “Import” button to load a property table into the meter. The user will then be prompted for the file to import.
Diagnostics The diagnostics screen is typically only necessary when the meter needs to be serviced. A Racine customer service technician can refer to the information provided by this dialog box to troubleshoot the meter. This dialog box takes a while to open because there is extensive information read from the meter. The “Read” button will refresh the screen with new data from the meter. The “Print” button will allow the user to print the information to a file or to a default printer.

Configuration Report The configuration report is a convenient tool to display all the customer configurable settings of the meter. The report generated by this dialog box is useful for record keeping and for servicing the meter. A Racine customer service technician can refer to the information provided by this dialog box to troubleshoot the meter. The “Read” button will refresh the screen with new data from the meter.
Calibration The calibration selection is only necessary when the meter needs to be serviced. The Racine customer service technician will utilize or direct the customer to the use of these settings.
The “Digital Pots” selection will allow the technician to change hysteresis data. Digital Pot Settings Pot Values: Read Unfiltered Audio Hyst: 5 Filtered Audio Hyst: 5 Write Close NOTE: Save the changes to EEPROM and put the meter in-service after making changes.
APPENDIX A - WIRING DIAGRAMS Use foil shielded cable in all installations. Ground the foil shield to the chassis ground terminals provided on the meter. The chassis ground is the only point the shield should be grounded. Refer to the meter operator’s manual for additional wiring and shielding information. The wiring diagrams illustrated below are for installations where no 4-20 mA pressure sensor is used.
Analog Pressure Gauge Wiring If an analog pressure gauge is used it must be wired as shown below to avoid inadvertent current paths. A single supply can be used to power the flow meter and the external pressure sensor. The 420 mA flow indication must be taken from the source side of the loop.
APPENDIX B - TROUBLE SHOOTING GUIDE Problem Resolution Low loop voltage The meter requires 15 volts DC at the power terminals. Measure this voltage at the meter and ensure it is 15 volts or greater. Incompatible operating system The Racine HART Interface will run on Windows 98, NT, XT, and XP. However, the program works best with Windows 98 and XP. The Racine HART Interface has on occasion run on PC’s with Windows 2000, but this operating system is not recommended.
