1. INTRODUCTION TO AdEM®-PTZ
AdEM®-PTZ is an electronic gas volume conversion device, which provides corrected
volume that is temperature and pressure corrected to standard conditions; applying
compressibility correction factor according to NX-19 or AGA8 or SGERG88 formula
(see Correction Equation for details). Romet combines the power of its field proven
gas measurement technology and integration of computer-based software to come
with the product AdEM®-PTZ. The device can be mounted on Romet rotary meters
or other manufacturers’ pressure bodies. AdEM®-PTZ can be used either as a stand-
alone device or linked to a computer running RometLink software. RometLink is a
powerful tool for device management and advanced data collection/energy
management system.

How to Specify Model
How it works
The AdEM®-PTZ is a solid-state electronic volume conversion module that is directly coupled to the magnetic housing
of the Romet meter body. The AdEM®-PTZ employs a magnetic sensing device to sense the rotation of the meter’s
outer magnet which produces a high-resolution input that represents the non-converted (UNC - uncorrected)
metered gas volume. The volumetric input pulses are converted to base measurement conditions (COR - corrected)
by compensating for temperature, pressure (live or fixed) and super-compressibility NX-19 or AGA8 or SGERG88 (live
or fixed).
COR = UNC x PFx TFx (Fpv)2 or COR = UNC x PFx TFx FZ
Where: COR = Corrected volume (ft3or m3)
UNC = Uncorrected volume (ft3or m3)
PF= Pressure correcting factor
TF= Temperature correcting factor
(Fpv)2= Super-compressibility correcting factor (Live Z factor for NX-19
method)
FZ= AGA8 or SGERG88 compressibility factor (Live)
The pressure and temperature correction factors are calculated by the formulas as mentioned in section 8. The
temperature is measured by an RTD or IC (optional) temperature sensor located in the temperature well or inlet
differential port (optional) of the meter. Pressure transducer is mounted inside enclosure of AdEM®-PTZ (¼ inch
NPT connector is available for pressure piping arrangement). The optional external temperature sensor location is
recommended for mating the AdEM®-PTZ module to Romet meter bodies that do not have an internal temperature
well.
Both parameter description and values that are integrated by the algorithms of the AdEM®-PTZ firmware (UNC
volume, COR volume, flow rate, date, time, etc.) are displayed on an 8 digit 14-segment semi alphanumeric liquid
crystal display (LCD).
A non-volatile EEPROM memory stores key parameter values, AdEM®-PTZ setup configuration, temperature sensor
calibration data and Audit Trail data in the event of power loss.
AdEM®-PTZ key parameters:
✓Current values of uncorrected and corrected volumes and measured parameters
✓Under/Over limit violation monitoring of Pressure, Temperature and Flow.
✓Present and Previous Day Volumes.
✓Averages, Maximum and Minimum values for pressure, temperature and flow.
✓Peak Flow stamped by date and time.
✓Battery status.
✓Last Hour Indexes stamped by date and time.
✓Malfunctions.
✓Uncorrected Volume Since Malfunction.

In addition to compensating for live pressure and temperature conditions, the AdEM®-PTZ has a low flow volumetric
linearization feature that enhances the rangeability of the Romet meter to 200:1 or better with an error of less than
1.0%. This feature, if activated, is automatically initiated at flow rates below 10% of the Qmax rating for the meter.
RometLink Software
Romet has developed a Windows based user-friendly software tool, RometLink, that runs on a Microsoft Windows
based computer. This software tool enables users to take full advantage of AdEM®-PTZ device’s advance features
and makes it easy to operate, configure and manage the device and data.
RometLink software is the primary user interface and tool for Setup/Configuration, Calibration and
Data/Parameter retrieval.

AdEM®-PTZ Typical Application
AdEM®-PTZ can be used in a variety of ways. It can be used as a stand-alone device which can be configured or
evaluated by portable keyboard. For ease of operation and advance functions, it is recommended to use Romet
RometLink communication software either through using direct cable connection to the computer (RS232 or RS485),
or remotely by using a Hayes compatible modem connection (including wireless modem).
A typical application scheme is given below.
Implemented Modbus protocol (type RTU) makes AdEM®-PTZ available for other communication and control
systems, e.g.: SCADA.
Communication link equipment is third party equipment and is the responsibility of the user.
Downloaded data can either be further investigated using RometLink software or can be exported to
Microsoft Excel application/PDF for customer’s own way of utilizing it.

2. GETTING STARTED
AdEM®-PTZ is usually supplied fully calibrated/preprogrammed and mounted to pressure body as per specifications
of each customer. The AdEM®-PTZ modules can be supplied for Romet pressure bodies as well as other
manufacturers’ pressure bodies. The module, when removed from the box, will be in Normal Display mode only.
When removing loose AdEM®-PTZ modules from the box, never lift by the Magnetic Input Sensor P/N 46-124-
0/49-124-0/46-124-120/49-124-120 or Temperature Sensor Cable P/N 46-303-0.
In Normal Display mode, the display will show the value for the converted (COR VOL) or unconverted (UNC VOL) as
per user specifications.
Keyboard Operation
How parameter display works:
There are two stages of displaying parameters:
-As first, parameter description is displayed –up to 8 characters.
-Secondly, (next press of keyboard scroll buttons ↓↑ or SB), value of the parameter is displayed –up to 8
digits with decimal point if applied.
AdEM®-PTZ comes with a Scroll Button in standard; the portable keyboard is available as an option. The details of
the keyboard are as below:
ESCAPE or CANCEL Normally used to wake up the unit, cancel a dialog or escape a menu or
parameter.
UP Used to scroll up menu items, a parameter list, available parameter
options or increment digit value.
DOWN Used to scroll down menu items, a parameter list, available parameter
options or decrement digit value.
ENTER Used to select a menu, validate a digit value or to select a parameter
option in Setup and Calibration Modes.
When operating in the Normal Display mode the COR VOL or UNC VOL appears on the display. Press the ESC button
to wake up the AdEM®-PTZ and access the first parameter of the Custom Display mode (refer to Section 3, Modes
of Operation). If an alarm or malfunction is present, it will be displayed instead of the Custom Display Mode. To
move to the Custom Display if an alarm or malfunction is displayed, press the ENT button once. While in Custom
Display Mode, the /buttons may be pressed to scroll through the parameters or at any time press the ENT button
to gain access to the main menu. Once in the main menu, the /buttons are used to scroll the program modes.
Press the ENT button to enter a mode or the ESC button to return to Normal Display mode.
Program protection against unauthorized access to the metrological programming (Set Up, Calibration & Proving) of
the AdEM®-PTZ is assured by the combination of a Password and sealable En/Dis Switch (Jumper). Refer to Section
4, Security for further information). A D-size lithium battery produces the intrinsically safe power.
