About the Scanner 3100 EFM
The Scanner* 3100 EFM is uniquely designed to serve as a stand-alone ow computer or as a network manager capable
of collecting and storing data from up to 20 Scanner 2000 Series ow computers. As a stand-alone ow computer, the
Scanner 3100 offers dual ow stream and bidirectional measurement and control, as well as the processing power to
handle the industry’s most challenging ow computations for liquid and natural gas measurement. For operations requir-
ing the monitoring of several measurement points, the Scanner 3100 combines up to 20 external wired or wireless Scan-
ner 2000 Series devices into a single scalable local area network that can be managed via a web browser-based interface.
Each of the three serial ports can support multiple wired Scanner 2000 Series devices or other external Modbus devices.
Optional wireless communications signicantly reduce installation costs and setup time and increase worker safety.
The device is explosion-proof and approved by for ATEX/IECEx Zone 1 hazardous area installations and for CSA Class
I, Division 1 hazardous area installations. It is designed for use with a 9-30 VDC external power supply (9 to 24 VDC in
Mexico installations) and two optional lithium battery packs for backup power.
The Scanner 3100 can be ordered with a multivariable transmitter (MVT) and paired with a cone or orice meter for ac-
curate measurement of liquids and natural gas. The Scanner device also computes the corrected (standard) amounts of
uid using signals from external turbine, positive displacement (PD), Venturi, Coriolis and ultrasonic ow meters and
integral or remote pressure and temperature sensors. The measured uids may be expressed as volume, mass or energy
accumulations or rates. See Table 1.4—Flow Rate Standards, page 23 and Table 1.5—Fluid Property and Energy Flow
Calculations, page 24 for a detailed description of supported calculations.
In addition to its two integral ow runs, the device supports 17 inputs and outputs and communications with chromato-
graphs, samplers, and densitometers.
The device logs daily and hourly ow data for each ow run, and provides one-second triggered logging for analysis of
critical events. High-speed communication via Modbus and Enron Modbus protocols makes it easy to integrate the Scan-
ner 3100 into other measurement systems. When congured for use with Modbus master protocol, each of the device’s
three serial ports can log up to 128 data points from external Modbus devices.

Web Browser-Based Interface
A web browser-based interface equips you to congure ow runs, gas streams, and inputs/outputs, calibrate inputs, and
view archive data from a laptop, tablet, smartphone, or other browser-enabled mobile device without installing software.
You need only an Ethernet connection and an IP address to connect to the device. Four user security levels are avail-
able for customizing access for up to 20 users. An electronic user manual (PDF) is embedded in the interface, providing
searchable on-screen help. To position the manual alongside the user interface for simultaneous viewing, congure your
laptop per the instructions provided in the Scanner 3100 Web Interface User manual.
