2 Product Description
2.1 Introduction
The Tek-CoVor 1300D Steam Quality Meter is used to measure the steam quality. It is a
combination of two-meter, i.e., modified Vortex and Cone DP Meter. This hybrid system is based
on the Boden principle, which gives the mass flow, volume flow, and fluid density outputs. The
correlation between density and non-density sensitive metering removes the actual dependency
of density in steam measurement. The hybrid system provides actual homogeneous density and
volume measurement, which offer 100% steam quality in steam measurement. The density and
volume measurements are used to calculate the total mass value. Tek-CoVor 1300D Steam Quality
Meter can have the DP meter verification system prognosis applied, which provides reliable steam
quality (steam dryness) measurement. It is a unique, cost-effective, and highly capable system.
2.2 Measuring Principle
The Tek-CoVor 1300D Steam Quality Meter with a single-phase flow, a Vortex Meter measures the
actual volumetric flow rate (Q). The Vortex Meter reads the vortex shedding frequency of the bluff
body (f) and relates it through the meter factor (K) to the volume flow rate (Q), as shown in
equation 1. This volumetric flow rate measurement is density insensitive.

Q =
With a single-phase flow, a differential pressure (DP) flow meter measures the volumetric flow
rate once the density is supplied from an external source. The DP meter volume flow rate

calculation is density (ρ) sensitive. Equation 2 shows the Cone DP Meter volumetric flow
equation, where E and At are fixed geometry terms, Cd is the discharge coefficient, and ΔPt is
the Cone DP Meter primary signal.
Q = EAC
As described by Boden’s work in the 1950’s, if a density sensitive meter (Cone DP Meter) is
cross referenced with a density insensitive meter (Vortex Meter) the density can be derived
internally by the system as shown in equation 3.

= 2P
The Tek-CoVor 1300D flow rate calculation is now calculated through equation 4, where the
vortex meter volumetric flow prediction (Q) and this internal density prediction (ρ) are used. No
external density measurement is required.

5.1.1 External Analog Connection to DP meters
As an option, DP meters may be connected through analog 4-20mA input. There are two
options of external analog connections:
• Using the External Input Board in the Tek-CoVor 1300D Steam Quality Meter, the board must
be installed accordingly in the stack and firmware of the micro-board re-flashed.
Additionally, External input must be calibrated using standard factory production
procedures or external calibration input of 4 and 20mA. In this option, only DP1 can be
connected. DP meter must be powered from an external power supply or the same power
supply used to power the PoE. Analog 4 to 20mA output of DP should be connected to input
pin 3 (-) and pin 4 (+) of Options2 connector. (pins a counted from left to right). Schematic
will be provided later.
• Using external 8 channel ADC ADAM-4 117. ADC must be configured for 4-20 mA input on
channels 0,2 and 2. Internal switches must be set in ADC for current measurements (in asshipped configuration, these jumpers are in voltage configuration). Although all three DPs
can be connected, only DP1 is used for quality calculations. ADC is read by the PoE RS485
link. It used default ADC settings of 9600 Baud, 1 stop, no parity. ADC must be configured to
communicate Modbus/RTU and use address = 2.
NOTE
5.1.2 Optional External 4 to 20 mA Input Wiring
The Tek-CoVor 1300D Steam Quality Meter is set to have Option 1 is used for the external
input. Programming menus that pertain to the optional 4 to 20mA input are in the Hidden
Diagnostic Menu.

5.1.3 Power UP
An external 24VDC power supply power the Tek-CoVor 1300D Steam Quality Meter. Connect
+ve and -ve wires of power supply to TCP connector JI to screw terminals marked appropriately
as DC+ and DC-. External DC input must be used in the HART option because it is also used to
power the HART modem and DP2. In the option of analog DP input meter may be powered by
PoE. Just plug, Ethernet cable into PoE adapter or PoE enabled switch.
5.1.4 Connection to LAN
Plug Ethernet drop off the cable from your local area network switch to the RJ45 connector. As
soon as you apply DC power, you should able to see LCD is showing information. You should also
see the blinking yellow LED on the RJ45 connector when the CATS Ethernet cable is plugged and
LCD of DP meters lit. DP meters show the pressure in inchH20, which shows that system is ready
for further configuration.

7. Press the EXIT key and answer YES to permanently save your changes.
Example for Calculating Output Current
Assume Output 1 is scaled as above for mass flow with 4 mA = 0 lb/hr and 20 mA = 100 lb/hr.
Output 1 current = ((Flow rate / 100) x 16 mA) + 4 mA
The following shows how to set Relay Alarm 1 to activate if the mass flow rate is greater than 100
lb/hr. You can check the alarm configuration in the Run Mode by pressing the keys until
Alarm [1] appears. The lower line displays the mass flow rate at which the alarm activates. Note:
all outputs are disabled while using the Setup Menus.
First, set the desired units of measurement:
1. Use keys to move to the Units Menu (see page 29).
2. Press key until Mass Flow Unit appears. Press ENTER.
3. Press key until lb appears in the numerator. Press key to move the underline cursor
to the denominator. Press the key until hr appears in the denominator. Press ENTER to
select.
NOTE: the meter ships from the factory assuming 0% return and has a 1000ohm resistor installed in the RTD #2
wiring location. This needs to be removed if the meter is to be used in a manner other than with 0% return and with
the customer supplied RTD in its place.
Use the Fluid Menu to configure the flow meter for use with common gases, liquids and steam.
Your flow meter is pre-programmed at the factory for your application’s process fluid.
The units of measurement used in the Fluid Menu are preset and are as follows:
Mole Weight = lbm/(lbm·mol), CRIT PRESS = psia, CRIT TEMP = °R, Density = Kg/m3 and
Viscosity = cP (centipoise).
Use the Time and Date Menu to enter the correct time and date into the flow meter’s memory.
The parameters are used in the Run Mode and the alarm and system log files.
Note: Time is displayed in AM/PM format, but military format is used to set the time. For
example, 1:00 PM is entered as 13:00:00 in the Set Time menu.
Example for Setting the Time
How to set the time to 12:00:00. You can check the time in the Run Mode by pressing the keys
until the Time & Date screen appears. Note: all outputs are disabled while using the Setup
Menus.
1. Use keys to move to the Time and Date Menu.
2. Press key until Set Time appears. Press ENTER.
3. Press key until 1 appears. Press key to move the underline cursor to the next digit.
Press the key until 2 appears. Continue sequence until all desired parameters are
entered. Press ENTER to return to the Time and Date Menu.
Use the Diagnostics Menu to simulate operation and review the system files. The system log files
contain time/date stamped messages including: power on, power off, programming time outs,
parameter faults, incorrect password entry and other various information relative to system
operation and programming.
The simulated inputs are for testing the meter to verify that the programming is correct. They are
also used to enter nominal operating temperature and pressure for the V only model. Simulated
vortex frequency allows you to enter any value for the sensor input in Hz. The meter will calculate
a flow rate based on the corresponding value and update all analog outputs (the totalizer display and output is not affected by a simulated frequency). The simulated pressure and temperature
settings work the same way. The meter will output these new values and will use them to calculate
a new density for mass flow measurement. Note: when your diagnostic work is complete, make
sure to return the values to zero to allow the electronics to use the actual transducer values. For
the V only model keep the temperature and pressure at nominal operating conditions.
If the meter display indicates a temperature or pressure fault, a substitute value can be entered
to allow flow calculations to continue at a fixed value until the source of the fault is identified and
corrected. The units of measure of the displayed values are the same as the units configured for
the flow meter.
The Calibration Menu contains the calibration coefficients for the flow meter. These values
should by changed only by properly trained personnel. The Coef Ck and Low Flow Cutoff are set
at the factory. Consult the factory for help with these settings if the meter is showing erratic flow
rate.
The Tek-CoVor 1300D Steam Quality Meter needs to be configured to be "visible" on your local
network. There are two methods of configuration:
• using static IP address
• using dynamically assigned IP address via DHCP (Dynamic Host Configuration Protocol)
For static configuration ask your network administrator which IP address to use. For industrial
automation applications the preferable method is using static IP address.
6.1 IPSetup Network Configuration Tool
IPSetup is used to configure network settings on your device such as IP Address, Mask, Gateway,
DNS Server. IPSetup uses a UDP broadcast on port 20034 to identify network devices when
activated within your system. Routers do not forward UDP transmissions. Therefore, IPSetup can
only be used on a local area network or the direct link. You need to run it on a PC connected to
the same switch as your device. This is related to configuration only.
IPSetup is commonly used for:
• Determining the DHCP assigned IP address of your device.
• Configuring the network settings of your device.
IPSetup can be downloaded from the file system or we can provide on USB flash drive. It
can be run on any Windows or Linux machine under Windows emulator WINE.
To configure a device with IPSetup steps are the following:
• The device must be on the same local area network or be a direct connection to your PC.
• Your PC's firewall must allow network traffic on port number 20034. If you do not see your
device, then temporarily disabling your firewall first to see if that is the cause.
• Click on a device in the "Select a Unit" window.
• Enter your configuration settings in the "NDK Settings" group.
• An IP address of 0.0.0.0 instructs your device to use DHCP.
• Once you have specified all your configuration settings, click on the "Set" button to
transmit them to your device.
• The DHCP assigned address or static IP address will appear in the description next to each
device in selecting a unit window.
6.1.2 IPSetup Does Not Display Your Device
If IPSetup does not display your system, this is one of the following reasons:
• A firewall on your PC is blocking the network port number 20034. Try to disable your firewall
temporarily to see if this is the cause.
• You are trying to talk to a device on the other side of a router. The PC and device must be
on the same LAN.
6.1.3 IPSetup FAQ
• Setting the IP address to 0.0.0.0 forced the application to use DHCP instead of a static
address.
• IPSetup shows the name of the application, as shown in figure 10. The name is composed of
the last 4 HEX digits of the unit's MAC address, for example - E46B. This default Unit name is
set as the so-called NetBios name. You may access the Unit by this name by typing it in the
WEB browser's address field, like http://E46B. This name may be changed on the
Configuration page of Unit's WEB Page.
• Besides IP, Network Mask, Gateway and DNS, do not change any other parameters, such as
UART, delay, baud rate, etc.
• Gateway is necessary if you plan to access devices from the Internet or other subnets of your
local network. It is recommended to provide the correct Gateway address. DNS is necessary
only if access to the Internet is needed for the device in the case, for example, accessing
Network Time Servers (not enabled in the current version of firmware). It may be set as
0.0.0.0.
• This configuration needs to be done only once at initial commissioning on the customer's
network.
• The static configuration could be done with a direct connection with Ethernet crossover
cable to your PC.

7 Meter Web Pages
The Tek-CoVor 1300D Steam Quality Meter has an internal WEB server to provide real-time
measurement information and configuration interface.
The Tek-CoVor 1300D Steam Quality Meter supports two protocols for accessing the WEB pages as
follows:
• HTTP - insecure connection to TCP port 80
• HTTPS - secure connection to configuration pages on TCP port 443
It is possible to connect to all pages using HTTPS instead of HTTP. The assumption is that
measurement data does not need to be secure, while configuration must always be encrypted.
The main WEB page shows the menu on the left. When powered up the meter, it scans for
connected meters first. This version is intended for master/slave configuration with multiple
meters connected to a single gateway. Typically, this Slave Address selector is not used and there
is always only one selection possible.
7.2 Steam Web Page
The main page for Steam Quality Meter is invoked by the menu link "STEAM".
This page shows readings from three Differential Pressure meters, i.e., DP1, DP2 and DP3. Only
DP1 readings are essential for steam quality calculations. The meter scans the HART line for the
presence of DP meters. In this table also shown variables read from Vortex Meter. The same values
may be monitored on the FLOW page. All the steam values use fixed units. The units of all other
Vortex values can be configured.
The page is automatically refreshed every 4 seconds. The calculations of steam values are done at
about the same time interval.
Vortex Meter Web Pages, invoked by menu links: FLOW, METER, FLUID and DIAGNOSTIC provide
real-time information about measured and configured parameters of Vortex Meter.
8 Web Configuration Interface
When clicking on the CONFIGURE Menu link opens the following page:
Connection to the Configuration interface is done using encrypted protocol HTTPS. When
connected for the first time, your browser and the unit need to do some verification. This process
is slightly different in different browsers. In Firefox, it looks as follows:
When the link "Click here if you are on the local network" is clicked, the page shown below is
opened.
Please, note that there is a button called "Advanced". The next page is shown with the button
"Add Exception" at the bottom if you click it. If you open this page in the right frame using the
second link "Click here if you are on the local network and reopen in this frame", the browser
does not show this "Add Exception" button. So, for the very first time connecting to new
"unknown" to your browser meter use first link, after that you may use a more convenient second
link and open configuration interface inside the frame.
By clicking "Add Exception" the following screen is opened:
Fig 16: Web Configuration after Add Exception clicking
Browser complains about our Tek-Trol certificate because it expects, as it typically happens, the
site's name, for example, myBank.org and getting instead just an IP address. You may view the
certificate to make sure you are connecting to the meter, not something else. Click "Confirm
Security Exception," and this certificate will be stored in your browser. The next time browser
knows which certificate to use for this particular IP. If you change the meter's IP address, you will
need to go through this procedure once again.
With other browsers, the procedure may be slightly different, but the final point is the same you need to get to the point when the browser asks you to confirm the certificate's exception.
On Windows IE Explorer, the browser will show page as shown in figure 17. You need to click the
link "Continue to this website (not recommended)". In some versions of IE, it may not show this
link. In such case upgrade IE to version 11 or better using a different browser, e.g., Firefox
Fig 17: Internet Explorer HTTPS Warning Page
After certificate acceptance is done, you may enter the configuration page. It will ask for
authentication. Use the Username "creator" for administrative access, allowing to change some
additional parameters or use general Username "owner". The password for both cases is
"16363".
It will show configuration page in full screen or in frame if second link is used.
All configuration forms are more or less self-explaining. Some explanation is needed for selecting
Fluid Type. It has two forms, including the selection of Fluid Type and selection of specific fluid
within selected Fluid Type.
The format of this form depends on version of PoE firmware: steam, standard PoE, Prognosis, etc.
Fig 22: Configuration Options
Configuration Options allow you to select between different configurations. These are just bits
set in 32 bits configuration word. All settings are retained between power cycles. Bits 1,2 and 4
are not used in Steam. Bit 16 (0x10) is selecting using of external analog DP read by Input board
in Tek-Trol. Bit 32 (0x20) - selects using external ADAM ADC as 4-20 mA inputs for DP1 to DP3.
Value DP1 to 3 Averaging setts number of counts to average. The main Steam page shows instant
and averaged values of DPs as well as calculated values.
DP1 to 3 ADC Scale and Offset set scale and offset accordingly of ADAM ADC measurements. The
calculated values used as DP input = adc*scale/0xffff + offset. ADC is 16-bit value between 0 for
4mA input and 65535 (0xffff) for 20mA input. So, to scale O to 1 00 inH2O of DP meters use scale
= 100 and offset = 0. To read actual 4-20 mA current used scale= 16 and offset=4.
9 Connection to meter from the Internet and Security Issues
Typically, your meter is connected to your Local Area Network (LAN) with non-routable Private
Network Address ( I 92.1 68.xx.xx, 1 0.xx.xx.xx, 1 72.1 6-31 .xx.xx). For connection to the meter from
anywhere on the Internet, two methods may be used:
• Connect through Virtual Private Network (VPN)
• Port Forwarding Technique
In case of VPN, your home PC is becoming part of your corporate network and you getting access to
all resources on your corporate LAN. Usually, your home PC is assigned the IP address from the
different subnet that your meter and, therefore IPSetup program will not work. You need to know
the IP address of the meter to connect. Contact your IT department about the availability of VPN
and connection instructions.
The second method is configuring the corporate firewall in such a way that you are getting access
to particular internal (LAN) IP by mapping it to your external corporate gateway IP and port number.
This is usually done by mapping like following. Assuming your corporate gateway is 50.202. 79. 132
and your meter IP on LAN is 10. 10. 1 0.75.
Example of port forwarding:
External IP 50.202.79.132 Port 8080 ==>mapped to==> 10.10.10.75 Port 80
External IP 50.202.79.132 Port 10502 ==>mapped to==> 10.10.10.75 Port 502
External IP 50.202.79.132 Port 10443 ===>mapped to==> 10.10.10.75 Port 443
Your IT should know how to do such configuration in corporate routers. All you need is to provide
information to IT on used network ports:
TCP port 80 Non secure access to main WEB pages. Read only. Protocol HTTP.
It is also possible to access meter using only secure connection via Port 443.
TCP port 443 Secure encrypted access to configuration pages. Protocol HTTPS, SSL.
Encryption 128 bit - does not require Export licensing.
User/password protected (secure)
TCP port 502 Access by automation software to Modbus/TCP server. Protocol Modbus/TCP
Optional:
TCP ports 20,21 Access to internal FTP server. Protocol FTP. User/password protected (insecure)
UDP port 20034 Broadcast discover protocol. Used to find units on the local Network.
It is not routable and therefore works only within the same subnet.
Used by IPSetup ( discover/IP config) and Auto Update (flash) programs.
Auto Update works across Ethernet switches. It uses UDP with direct address.
It may be blocked by most routers.
TCP port 20034 Firmware update using TcpUpdate utility. (Not enabled in Rev 1.0 of firmware).
All corporate gateways which are more advanced than simple "home" routers can provide
additional security-enhancing measures, like using "sourcing" addresses allowing access only from
certain individual IPs or networks. If security concerns are high, you may limit access to the meter
using encrypted protocol only: port 443, https. On special request, Tek-Trol can add the special
capability of Access Control List (ACL) to insecure by definition Modbus protocol. Using ACL users
may define a number of hosts or networks from which connection to Modbus port 502 can be
accepted. Normally this function can be implemented in a corporate firewall. ACL in the meter may
be needed when it is exposed to the Internet directly.
General information about Port Forwarding and instructions on how to set it up in simple home
routers available everywhere. For example,
Tek-Trol TCP meter supports industry standard automation protocol Modbus/TCP.
Table 1 : Modbus General Specifications
10.1 Modbus Utilities
• We include for customer convenience two applications which may be used during integration
into your automation system:
o MbusGui.exe Windows GUI application for reading Modbus registers of the meter.
o mbus.exe Generic DOS console application for reading Modbus/TCP registers.
• These two applications are stored on the SD card inside the meter.
• To download them click on the menu link "LOG DATA" and then select directory EXE.
• Right-click on MB US.EXE or MBGUI.EXE link to download it to your PC.
• Figure 24 shows the simple Modbus/TCP client configured for use with the meter. The
names and locations of registers are stored in the mbgui.ini file.
• This file is created at startup and contains default definitions. The structure of the
application uses the following approach accepted for meters supporting Modbus/RTU.
• All registers are grouped by data types: float, long, etc. Two groups of registers 0 contain
most of the real-time data and Group 200 has steam-related data that can be viewed on a
timer once in two seconds on the left panel.
• Selecting a group in the "Read Group" selector will show it in the right forum.
• You can rename the application to something more meaningful to you (please avoid spaces
in the program name). In this case, it will rename as per the INI file. By this, you may create
several clients for different meters.
• This application is compiled to run on the Windows machine. It also can be run on Linux or
MAC machine with 586 architecture under Windows emulator WINE. (MAC case was not
tested).
• Button "Read Configuration" read all configuration-related registers and shows them on
the right panel. You can save it to a file by clicking the "Save File" button.
• Later you can load this or other saved configuration file and force it to the unit to
reconfigure it. Before pushing the file to the unit, you may edit it and leave only the
registers you want to change. Please, be careful using this option.
10.3 Console Modbus/TCP client MBUS. EXE
• This is simple Modbus/TCP client for reading Modbus registers and output data in specified
• Retrieving log files could be automated using Internet-standard utility WGET. This utility
readily available on Linux machines and for Windows can be downloaded from here:
• https://www.gnu.org/software/wget/ or install Linux simulator on Windows WinBash,
which also contains WGET: http://win-bash.sourceforge.net/
• To read daily file for a specific date, use the following WGET command: WGET
http://10.10.10.79/LOGS/2016/05/160527.CSV (where first 2 digits -year, next -month, next
day). This instruction will download daily log file for date: 05/27/2016
You may use FTP access to clean SD card by removing unnecessary data or
Tek-CoVor 1300D
11.2.2 FTP
• The meter has the capability of accessing the file system on the SD card via FTP protocol.
• For that, you may use any specialized FTP client or even File browser on Linux or Windows
systems.
• In Windows Explorer, enter in address field ftp://10.10.10.79 or whatever is your meter's IP.
• You may be asked the first time for the Username and Password. Use Username: "owner"
and Password: "16363".
• You will get almost full access to the file system on the SD card. You may copy files, delete
files and directories. Creating directories is not allowed.
Fig 35: Data Log by FTP
• FTP access may be automated with mentioned above WGET application. The string to query
single file is the following:
WGET ftp://owner: 16363@10.10.10.79/LOGS/2016/05/160527 .CSV
*Note how to supply username and password when accessing via FTP.
NOTE
wrong directories created due to misread real-time Clock of the meter.
12 Firmware Update
• Tek-CoVor 1300D Steam Flow Meter firmware can be updated on-line. For that, there are two
applications:
o Auto Update Standard update utility using UDP protocol. (Local network only)
o TcpUpdate Update utility using TCP protocol allowing access from other systems.
• In revision 1.0 of TcpUpdate is disabled.
• The Auto Update should always be used.
• The Auto Update application can be downloaded from EXE directo1y on the SD file system of
