Introduction
The eFlo 2.0 instrument is Super Systems Inc.’s latest electronic flow meter. eFlo works by
measuring the differential pressure (the difference in pressure of a gas at two points) of a gas
flowing through a specially designed opening in the gas flow assembly. Based on properties of
the flowed gas, the differential pressure can then be used to calculate the flow rate of the gas.
eFlo 2.0 uses a mathematical curve to calculate the flow of a gas and features built-in
diagnostic information, flow rate and pressure alarms, and a flow rate totalizer. The automatic
meter can be set to automatic or manual valve control mode. Automatic valve control mode
allows the eFlo to use a flow rate or valve position setpoint as a basis for adjusting the valve
(and thus the gas flow) using a built-in valve motor. The setpoint can be programmed manually
by the user or obtained by the instrument from a 4-20 mA analog signal or a digital signal over
RS485. Manual valve control mode allows the user to manually set the valve position through
the interface.
eFlo 2.0 is built for use in harsh industrial environments.
This manual also covers configuration and control using the eFlo web interface.

Safety Information
Observe the following safety requirements when configuring, operating, servicing, or
maintaining the eFlo instrumentation. If the device is used in a manner not specified in this
manual, protection provided by the equipment may be impaired.
WARNING!
The eFlo instrument is NOT guaranteed to provide gas shutoff, nor is it designed to do so. For
reliable gas shutoff, incorporate a valve that provides positive gas shutoff. Ensure that all gas
flow equipment is in compliance with National Fire Protection Agency (NFPA) requirements,
including those found in NFPA 86. Failure to follow these requirements could result in
flammable gas leaks into the unit.
Ensure that the air and gas mixture ratio settings are within the specifications provided in this
manual. Exceeding specified values could result in hazardous conditions.

Installation Procedure
Installing the eFlo unit consists of a mechanical installation and an electrical installation. The
mechanical installation includes mounting as well as inlet and outlet piping. The eFlo unit will
be assembled prior to shipment. Before beginning installation:
Ensure that all fittings and connections are tightly secured prior to beginning
installation.
Ensure that all expected components are present. Contact SSi at [phone] if you
have questions.
Mechanical Installation
Clearance
When installing the device, leave enough room on either side (3” is recommended) to allow
users to adjust, remove and replace the existing fittings. Also ensure that the device is installed
in a location that allows for easy access to the power connection.
Mounting
Proper mounting is essential for the successful operation of the eFlo instrument. Please use
the mounting template (included with the eFlo unit or available at
www.supersystems.com/eflo/) to ensure accuracy.
The eFlo can be supported by pipe without using the bolt holes if desired. However, if mounting
in this manner, ensure that the pipe is rigid enough to support the weight of the meter.
When installing the device, the shutoff valve or blocking solenoid should ideally be located
before the meter.
Plumbing
The outlet openings measure 1.25” NPT. Use of bushings or reducers at these connections is
acceptable as long as the smallest pipe diameter is not smaller than the installed orifice plate.
See certification for that meter to determine actual orifice diameter. Contact SSi at (513) 772-
0060 for questions about pipe sizing.
Thread Sealants:
Teflon or natural gas-rated pipe tape or pipe dope is acceptable for non-corrosive gases. For
corrosive gases, pipe tape is not recommended, unless the manufacturer specifies that it is
rated for gas(es) being flowed through the meter.
NOTE: When installing the device, ensure that excessive tape or dope does not fall into the
meter, as this can damage sensors, plug sensor lines, prevent flow through the meter, and
prevent the device from functioning properly.

Connection Tightness:
After thread sealant is applied, tighten all connections by hand (3.5-6 turns, depending on pipe
size), then use the following Turn Past Finger Tightness guide to complete the tightening
process:

Table 2- TPFT Guide
NOTE: Never loosen a fitting for correct alignment. Doing so will prevent the thread from
maintaining a proper seal.
CAUTION: Do not overtighten the connection. Overtightening can damage threads, pipes,
fittings, and the eFlo device.
Leak Checking
Before operation, all plumbed components should be leak checked. To avoid damage to
sensors and other components, check with SSi for the maximum pressure for the sensor in
your eFlo device (the installed sensor may vary based on the parameters needed in your
particular application).
IMPORTANT!
Ensure that the inlet pressure is within specified parameters for your eFlo unit.

Initial Network Configuration
This section is intended for use by persons familiar with Ethernet network setup.
In order to work correctly, the eFlo unit must be properly configured for the network to which it
is connected.
NOTE: By default, the IP address of the eFlo unit is static, and Dynamic Host Configuration
Protocol (DHCP) is disabled. These settings can be adjusted through SSi’s nLocateIP software
(see below), the web interface (Using the Web Interface), or through the eFlo keypad.
If you already know the IP address of the web interface, skip to the Error! Reference source not
found.. The network configuration is described in this section.
The eFlo unit will use a default IP address of 192.168.1.200. If the unit is using the default IP
address, that IP address can be used to access the web interface (for more information on the
web interface, refer to the Error! Reference source not found. section.
The IP address of the unit can also be found by using SSi’s nLocateIP software. This method is
described in the following subsection.
nLocateIP Method
Once the unit is connected to the network, you should be able to locate it using SSi’s nLocateIP
software. This program is available from SSi. To use it in locating the unit on the network, follow
these steps on a Windows-based PC:
1. Ensure that the unit is connected to the network.
2. Open the nLocateIP program

3. Once the program opens, click the Search button. The program will begin searching for SSi
devices connected to the network.
4. Look for identifying text in the list of instruments. It includes the type of instrument and
serial number. It also provides the IP Address information for the sensor.
5. Click the Configure button and choose the sensor to change its IP Address settings.
6. Click on the device description to highlight it and click the OK button. This will display the
device’s IP settings, which can be changed to match the network to which it’s connected.
