About the QRATE Scanner 3300 Integrated Control Flow Computer
The QRATE Scanner 3300* integrated control flow computer is uniquely designed to serve as a stand-alone flow com-
puter or as a network manager capable of collecting and storing data from up to 20 NUFLO Scanner 2000 series flow
computers. As a stand-alone flow computer, the QRATE Scanner 3300 offers dual flow stream and bidirectional measure-
ment and control, as well as the processing power to handle the industry’s most challenging flow computations for liquid
and natural gas measurement. For operations requiring the monitoring of several measurement points, the QRATE Scan-
ner 3300 combines up to 20 external wired or wireless NUFLO Scanner 2000 series flow computers into a single scal-
able local area network that can be managed via a web browser-based interface. Each of the three serial ports can support
multiple wired NUFLO Scanner 2000 series flow computers or other external Modbus devices.
The QRATE Scanner 3300 is designed to be panel mounted. If desired, the display has also been designed in such a way
as to all the main enclosure to be mounted on a rack while the kiosk touch display is mounted a distance away from it.
The optional wireless communications may reduce cost by negating the need of running Ethernet to the device.
The device is approved by CSA for ordinary locations. It is designed for use with a 9-30 VDC external power supply.
The QRATE Scanner 3300 device computes the corrected (standard) amounts of fluid using signals from external tur-
bine, positive displacement (PD), Venturi, Coriolis and ultrasonic flow meters and integral or remote pressure and tem-
perature sensors. The measured fluids may be expressed as volume, mass or energy accumulations, or rates. See
Table 1.5—Fluid Property and Energy Flow Calculations, page
for a
detailed description of supported calculations.
The QRATE Scanner 3300 kiosk touch display, when the device is connected via Ethernet or Wi-Fi, allows the user to
fully configure it directly through the display. This simplifies the steps necessary for setup, and also simplifies any addi-
tional calibration or configuration in the future.
In addition to its two integral flow runs, the device supports 17 inputs and outputs and communications with chromato-
graphs, samplers, and densitometers.
The device logs daily and hourly flow data for each flow 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
QRATE Scanner 3300 into other measurement systems. When configured 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 configure flow runs, gas streams, and inputs/outputs, calibrate inputs, and
view archive data from the kiosk touch display, 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 available 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, configure your kiosk touch display per the instructions provided in the QRATE Scanner 3300 Web Interface
User manual.
