Figure 5.10 5.3.3 Submenu “Measuring Units” Use the “Engineering Units and K-Factor Menu” to navigate to “Measuring Units” menu option. This option allows configuration of the flow meter/controller with the desired units of measurement. These are global settings and determine what appears on all process information screens and data log records. Units should be selected to meet your particular metering needs. A total of 47 different volumetric and mass-based engineering units are supported (See Table 5.
The following selections are available: 1 second, 60 seconds (1 minute), 3600 seconds (1 Hour), 86400 seconds (1 Day). The default entry is 60 seconds. If a massbased User-defined Unit is desired, the “UD Unit Use Density” parameter must be set to “YES”. The default entry is “NO” so the Fluid STD Density parameter is not used for flow rate calculation. TABLE 5.

5.3.5 Submenu “K-Factors Settings” Conversion factors relative to Nitrogen are convenient to use when the flow meter/controller mated to the TIO is calibrated for Nitrogen and another gas is required to be measured/controlled. Conversion factors relative to Nitrogen for up to 22 common gases are stored in the TIO (see APPENDIX II). In addition, provision is made for a user-defined conversion factor.
a) Flow Alarm Mode (Tabular entry) This function determines whether the Flow Alarm is Enabled or Disabled. The following selections are available: Enabled or Disabled. The default entry is Disabled. Alarm Mode selections can be set with the UP and DN buttons and are accepted by pressing ENT button. b) Low Flow Alarm (Numerical entry) The limit of required Low Flow Alarm value can be entered in increments of 0.1% from 0 - 100%F.S.
, NOTE: For Flow Meter function the value of the High Flow Alarm must be more than the value of the Low Flow Alarm. d) Flow Alarm Action Delay (Numerical entry) The Flow Alarm Action Delay is a time in seconds that the Flow Rate value remains above the High limit or below the Low limit before an Alarm condition is validated. Valid settings are in the range of 0 to 3600 seconds (default value is 0, no delay).
, NOTE: Before enabling the Totalizer, ensure that all Totalizer settings are configured properly. Totalizer Start values must be entered in the currently active Volumetric or Mass flow engineering unit. The Totalizer will not totalize until the Process Flow Rate becomes equal to or more than the Totalizer Start value. Totalizer Event values must be entered in currently active volume or mass based engineering units.
The default entry is Disabled. Totalizer #1 Auto Reset selections can be set with the UP and DN buttons and are accepted by pressing the ENT button. f) Totalizer #1 Auto Reset Delay (Numerical entry) This option may be desirable when the “Totalizer #1 Auto Reset” feature is enabled. Valid settings are in the range of 0 to 3600 seconds (default value is 0, no delay). g) Reset Totalizer #1 (Numerical entry) The Totalizers #1 reading can be reset by selecting the “Reset Totalizer #1” menu option.
, NOTE: Before enabling the Totalizer, ensure that all Totalizer settings are configured properly. Totalizer Start values must be entered in currently active Volumetric or Mass Flow engineering units. The Totalizer will not totalize until the process flow rate becomes equal to or more than the Totalizer Start value. Totalizer Event values must be entered in currently active volume or mass-based engineering units.
e) Totalizer #2 Power On Delay (Numerical entry) Sometimes it is convenient to start the Totalizer only after a specified power-up delay interval. Most of the mass flow meters and controllers require some warm-up time from the power-up event in order to stabilize process variable output and to get accurate reading. “Totalizer #2 Power On Delay” option allows setting a specified time interval which must elapse from the device power-up event before the Totalizer will be activated.
5.3.9 Submenu “Pulse Output” The flow Pulse Output is operates independently from Totalizers and is based on configuration settings (see Figure 5.7) which can provide pulse frequency proportional to instantaneous fluid flow rate. The LCD/keypad and digital communication interface commands are provided to: • • • • , Enable/Disable Pulse Output Start Pulse Output at preset flow rate (0.0 – 100.0 %F.S.
5.3.10 Submenu “Opt. Outputs Settings” Two sets of optically-isolated digital outputs are provided to actuate user-supplied equipment. These are programmable via digital interface or LCD/Keypad such that the outputs can be made to switch when a specified event occurs (e.g. when a Low or High Flow Alarm limit is exceeded, when the Totalizer reaches a specified value), or it may be directly controlled by user. The user can configure each optical output action from 9 different options: • Disabled: No Action.
5.3.11 Submenu “Display Settings” Process Information screens can be configured to be static (manual control) or dynamic (automatic sequencing). In the static mode pressing the UP button allows the user to page through the PI screens in the forward direction. Pressing DN button, pages through the PI screens in the reverse direction. When the last PI screen is reached, the firmware “wraps around” and scrolls to the initial PI screen once again.
In the example shown above, all PI screens are enabled. Each PI screen is assigned to a corresponding bit in the PI Screen Register. In order to change PI Screen mask settings the user should select the desired screen using UP and DN buttons and then press RIGHT button. The asterisk will appear/disappear on the right side of the corresponding screen. The asterisk signifies that the screen is enabled. In order to disable the screen, the corresponding asterisk must be removed.
, NOTE: Based on “Device Function” (device function as flow meter or flow controller) settings, different parameters may be displayed in the Process Information (PI) screen (See Figure 5.4) and different features of the TIO device may be enabled or disabled (set point control only enabled when TIO is configured as flow controller). Also some features (e.g. Flow Alarm) may have different behavior. Be sure the “Device Function” parameter is set according to the actual device being used. 5.3.
, , NOTE: Address 00 is reserved for global addressing. Do not assign, the global address for any device. When command with global address is sent, all devices on the RS-485 bus execute the command but do not reply with an acknowledge message. NOTE: Do not assign the same RS-485 address for two or more devices on the same RS-485 bus. If two or more devices with the same address are connected to the one RS-485 network, a communication collision will take place on the bus and communication errors will occur.
c) Flow Power Up Delay (Numerical entry) Sometimes it is convenient to start the process input signals after the specified power-up delay interval. Most mass flow meters and controllers require some warm-up time from the power-up event in order to stabilize process variable output and get accurate reading. “Flow Power UP Delay” option allows a set specified time interval which must elapse from the device power-up event, before processing of the input signals will be activated.
f) Analog Input Calibration , NOTE: The analog inputs available for the TIO were calibrated at the factory. There is no need to perform analog input calibration unless the CPU IC, input amplifier IC or passive components from the analog input circuitries were replaced. Any alteration of the analog input scaling variables in the EEPROM table will VOID the calibration warranty supplied with instrument.
5.3.15 Submenu “Signal Conditioner” A noise reduction filter algorithm (Running Average or Noise Reduction Filter) is available in the flow meter when pulsating flow or especially noisy signals are encountered. The Flow Linearizer algorithm is also available when flow linearity must be improved. There are three parameters which make up Running Average Filter: • Number of Samples • Time Interval • Error Limit They are described individually below.
d) NRF Error Limit (Numerical Entry) The Error Limit value can be selected between 0.0 and 10.0 % F.S. (for consistency) . The value represents the difference of the signal sample from previous measured value. The Error Limit is configured to reject noise spikes within the flow range while allowing normal variation of the flow signal. The factory default setting 2.0% of full scale optimizes noise rejection in most applications.
, Note: It is recommended to use Aalborg7 supplied calibration and maintenance software for linearization table calibration. This software includes an automated calibration procedure which may radically simplify reading and writing for the EEPROM linearization table. 5.3.16 Submenu “Program Set Point” The Program Set Point Control allows execution of custom, user-preset programs of up to sixteen steps.

Totalizer#1 cannot be reset if ResetLock (EE index 70) value set to 1. NOTE: Start Totalizer at Flow value must be entered for in %FS (0.0 – 100.0). Limit volume must be entered in currently selected EU.
83 Pulse Output COMMAND NAME NO. COMMAND Pulse active time in ms must be at least twice less than pulse period (1/F). Example: Maximum flow rate: 600 liter/min (600 liter/min = 10 liters per second) If Unit/Pulse is set to 10 liters per pulse, the output will pulse once every second (F=1 Hz). EU must not be time based. It is recommended to set the unit/pulse value equal to the maximum flow in the same units per second. This will limit the pulse to be no faster than one pulse every second.
84 Units of measure COMMAND NAME Igal MilL Mton Bbl – – – – Imperial Gal million liters Ton (metric) Barrels Density Argument: Y – use density N – do not use density For User-defined units: k-Factor value represents conversion value from L/min. Time base argument: S – seconds M – minutes H – hours D – days Note: The units of the Totalizer output are not per unit time. Set units of measure for flow rate and Totalizer reading.
