Product Description
The Smith Meter® microFlow.net™ Gas is a micro-processor based single meter, single product electronic flow computer
instrument that monitors continuous gas flow applications. The unit can operate either as a stand-alone instrument
or part of a SCADA system.
Optimum measurement accuracy is attained through continuous linearization of the meter factor with changes in
flow rates. Volumetric correction and energy are calculated using published AGA/ISO equations providing precise
measurement results.
The dynamic real-time display of the current actual operating conditions of the system provides the operator with
valuable system information while the system is operating.
The microFlow.net Gas provides several features:
• Ethernet Connectivity
• Three Multi-Drop Serial Communications Ports
• Event Logging / Audit Trail
• User Configurable I/O
• Three Security Levels
• Optional Battery Backed Display per OIML
• Programmable Language/Messages
• Sampler Control
• Smith Meter MPU Gas Ultrasonic Meter Interface

Section I – Introduction
How To Use This Manual
This manual is to be used as an operators guide for the microFlow.net Gas.
This manual is divided into the following sections: Introduction, Display and Controls, Run Mode, Program Mode,
Diagnostics, and Index.
The “Display and Controls” section describes the microFlow.net Gas's physical display screen and keypad as well
as some of the basic messages that would initially occur.
The “Run Mode” section describes the typical operation of a microFlow.net Gas and the read only "Diagnostics".
The “Program Mode” section describes the mechanics of marking configuration changes to a microFlow.net Gas
using the integral display and keypad. See the Reference Manual for details of the parameters that are affected in
the Program Mode.
The “Index” is a comprehensive listing, with page numbers, of all subjects covered in this manual.
The examples presented in this manual are for clarity and operator convenience. The values might vary for specific
installations and/or operations.

Section II – Display and Controls
microFlow.net™ Gas Display and Controls
The user interfaces with the microFlow.net Gas through either through one of its several communications ports or
via the display and keypad found on the face of the instrument. The display and keypad alter the format and function
based upon the mode (Run Mode, Programming Mode…) that the instrument is currently operating in. The following
provides previews to the various screens as well as the keypad functions associated with the various modes.

Section II – Display and Controls
Power Up
The following describes the events which occur when the power is applied to a microFlow.net Gas. Upon power up
the microFlow.net Gas goes through a start up sequence. The start up screen will be displayed while a RAM test is
being performed.
After initialization, the microFlow.net Gas will display the default screen based on the configuration set by the user.
See the Operator Reference Manual (MNFG002) for more detail regarding the selection of the default display.
The “ALARM” message will blink at the bottom of all run-time screens if an alarm conditions exists.
Otherwise, the “MORE” message will be present at the bottom of all run-time screens.
Once the initial screen is displayed, the operator can scroll through other run-time screens by pressing the right/
left cursor buttons. This will sequence through the following screens. If the programming calls for a user config-
ured display to be the initial run-time screen shown at power-up, it will be included in the following sequence of
displays.
