Section 1—Introduction
The NuFlo Scanner 2000 microEFM packs the gas, steam, and liquid measurement capabilities commonly
A single lithium battery pack typically powers the instrument for more than a year, making it ideal for remote
Combining the differential pressure and static pressure inputs of an integral MVT with a process temperature
input, the Scanner 2000 offers everything needed for an AGA-3 or cone meter run in a compact, explosion-
®
Alternatively, the Scanner 2000 can be paired with a pulse output gas meter to obtain gas measurements in
When liquid measurement is the goal and pressure inputs are not required, simply purchase the Scanner
The addition of an optional expansion board expands the input/output capabilities to include a second turbine
via industry standard Modbus® and Enron Modbus® protocols makes it easy to integrate the Scanner into other
