UNPACKING THE DPM MASS FLOW METER

1.1

Your DPM Mass Flow Meterwas carefully packed in a sturdy cardboard carton, with
anti-static cushioning materials to withstand shipping shock. Upon receipt, inspect the
package for possible external damage. If the unopened package is damaged, contact the
shipping companyimmediately to make a report.

1.2

Open the carto n carefully from th e top and inspect for any sig n of concealed shippi ng
damage. If there is any damage, in addition to contacting the shipping company, forward
a copy of any damage reportto yourdistributoror to Aalborgdirectly.

When unpackin g the instrument, make sur e that you have all the items indi cated on
Packing List. Promptly report any discrepancy.

It is mandatory that any equipment returned for service be purged of any
hazardous contents including, but not limited to, toxic, infectious,
corrosive or radioactive material. No work shall be performed on a returned
product unless the customer submits a fully executed and signed SAFETY

Maximum operating line(common mode)pressure for "BREEZE" Low Differential Pressure
DPM04/14/24/34/44/54 series flow meters is 50PSIG (3.44 Bar). If the installation
line pressure is more than 50 PSIG(3.44 Bar), a pressure regulator must be installed
upstream of the flow meter to bring pressure down to 50PSIG (3.44 Bar).

Maximum operating line (common mode)pressure for DPM07/17/37/47/57/67/77 series flow
meters is 120PSIG (8.3 Bar). If the installation line pressure is more than 120 PSIG (8.3

maximum pressure in the gas line must not exceed 120PSIG (8.3bar).
Applying pressure above 120 PSIG (8.3 bar) will cause permanent damage

The DPM series flow meters integrate precision a differential pressure sensor
which accurately measures pressure drop across the special restriction flow
element (RFE). The geometry of the RFE is designed to ensure laminar flow in
each branch within the entire range of operation of the DPM instrument.
According to principles of fluid dynamics, the volumetric flow rates of a gas in the
laminar flow conduits are proportional to differential pressure across the
restriction flow element. In addition, precision absolute pressure and temperature
sensor readings are used to calculate mass flow rate using ideal gas laws.

The DPM flow meter supports multi-gas functionality which allows users on site to
select the desired measured gas using local Display/Joystick interface or digital
communication interface. See Tables X - XVIII which provide lists of supported
gases.

The DPM flow meter can display flow rate in 43 different mass flow or 15 different
volumetric flow engineering units. Flow meter parameters and functions can be
programmed locally via optional OLED/Joystick interface or remotely via the RS­232/RS-485 interface or optional Modbus RTU interface. DPM flow meters
support various functions including two programmable flow totalizers; low, high or
range flow; temperature and pressure alarms; automatic zero adjustment
(activated via local or digital communication interface); programmable solid state
relay (SSR); programmable 0-5 Vdc, 0-10 Vdc or 4-20 mA analog outputs; user­programmable pulse output (via SSR); and self-diagnostic alarms. Optional local
OLED readout with adjustaEOH brightness level provides mass and volumetric
flow rate, total volume reading in currently selected engineering units, and

If a flow of more than 133% the nominal maximum flow rate of the Mass Flow
Meter is taking place (displayed mass flow reading is flashing), a condition
known as "swamping" may occur. Readings of a "swamped" meter cannot be
assumed to be either accurate or linear. Flow must be restored to below 133%
of maximum meter range. Once flow rates are lowered to within calibrated
range, the swamping condition will end.

Based on meter configuration, different parameters may be displayed in the
Process Information (PI) screen by moving the control joystick (see Figure

7) Up or Down (DN). Process Information screens can be configured to be
static or dynamic (see Section 6.4.13.2 “Display and Process Information
(PI) Screens”). Using PI Screen Mask settings, the user can enable
(unmask) or disable (mask) up to 6 different process information
combinations.

the forward direction, while moving the joystick DN pages through the PI

firmware “wraps around” and scrolls to the initial PI screen once again.

In the Dynamic Display Mode, the firmware initiates automatic screen
sequencing with user-adjusted screen Cycle Time (see Section 6.4.13.2
“Display and Process Information (PI) Screens”). When the last PI screen is
reached, the firmware “wraps around” and scrolls to the initial PI screen
once again.

The diagram in Figure 13 gives a general overview of the standard top-level
display menu structure (when running firmware version A001). The Esc
push-button is used to toggle between the Process Mode (PI screens) and
the Setup menus, and to return to upper menu level.

In order to move through the menu items, the user must move the joystick
UP and DN. When the last item in the menu is reached, the menu “wraps
around” and scrolls back to the beginning of the menu items list. Similarly,
when the first menu item is highlighted and the joystick is moved UP, the
menu “wraps around” and scrolls down to the end of the menu item’s list. In
order to select the desired menu item, the user must press the joystick
down (this action is equivalent to the Enter button). To go back to upper
menu level, the user must press the Esc button.

All process configuration parameter settings are password-protected. In
order to access or change them, Program Protection (PP) should be
disabled. Each time the device is powered up, the Program Protection is
enabled automatically. By default, the device is shipped from the factory
with the Program Protection (PP) password set to Zero (PP Disabled). If the
PP password is set to Zero (Disabled), entering a PP password is not
required. A subsequent screen will appear and the Program Protection
menu item will be selected:

There are two methods of data entry:

x Direct numerical entry.
x Tabular Input from a menu.

If the menu with direct numerical entry is selected, move the joystick UP or DN
to increase or decrease digit value between 0-9. Move the joystick RIGHT or
LEFT to move the cursor to another digit position. When the desired value is
entered, use joystick equivalent of an ENT button to accept (to be saved in the
EEPROM) the new value

acceptability. If data is not acceptable, it is rejected and a message
is generated to indicate that the new data has not been accepted.

If the menu with tabular entry is selected, the available menu options can be
set using the joystick UP and DN positions and are accepted by pressing the
joystick equivalent of an ENT button.

6..44..22

In order to get access to “Change Program Protection (PP) Password”
menu, Program Protection must be disabled. If PP password is set to Zero
(Disabled), entering PP Password is not required and PP can be disabled
from “Program Protection” menu (see Figure 9). If PP Password is set to
any value more than Zero, the firmware will prompt with “Enter Program
Protection Password” (see Figure 10). The user must enter a program
protection code (up to 3 digits). If the PP password is lost or forgotten,
contact the factory or your distributor.

During data entry, the input values are checked for

Use the “Units of Measure" Menu to navigate to Measuring Units settings for
Mass Flow, Volumetric Flow, Pressure, and Temperature readings. This option
allows configuration of the flow meter with the desired units of measurement.
These are global settings and determine what appears on all Process
Information screens and in all data log records. Units should be selected to
meet your particular metering needs. A total of 44 different mass-based
engineering units (Standard, Normal and True Mass) are supported (see Table
VI). A total of 15 different volumetric flow rate units are supported (see Table
VII).

Supported Pressure units of measure are listed in Table VIII, and Supported
Temperature units of measure are listed in Table IX.

In addition to conventional flow units, user-defined flow engineering units
may be selected. Use the “Engineering Units and K-Factor” menu to
navigate to the “User-Defined Units” menu option. This option enables user­defined configuration of any engineering unit required for process
measurement.

The following three parameters are available for this function:

x UD Unit volume K-Factor (defined in Liters)UD Unit time base

x UD Unit use density (units with or without density support)

Before using the User-Defined Unit, be sure the proper conversion factor of
the new unit, with respect to one liter, is set. The default entry is 1.00 Liter.
Also, proper time-based values for User-Defined Units must be set.
