Nuflo Scanner 2000 microEFM

The NuFlo Scanner 2000 microEFM packs the gas, steam, and liquid measurement capabilities traditionally found in large flow computers into a compact, low power instrument.

Simplicity and ease of use are integral to this instrument’s design. Basic parameters can be configured quickly from a keypad inside the enclosure. All other parameters are easily configured using a PC or laptop and the ModWorX™ Pro software provided free with every Scanner 2000 purchase.

The Nuflo Scanner 2000 is an economical chart recorder replacement, a flow computer, and a stand-alone totalizer. Its measurement capabilities include compensated gas, steam, and liquid measurements based on the differential pressure input supplied by an orifice plate or a cone meter, or the frequency input from a turbine meter. A turbine input can be used for liquid measurement or compensated gas measurement in accordance with AGA-7. Modbus® protocol and two RS-485 communication ports allow remote communication to host systems. The instrument’s ability to measure gas and water simultaneously is also a clear advantage for coalbed methane operators.

The Scanner 2000 microEFM is available in two packages: an explosion-proof package certified for use in hazardous areas, and a weatherproof package.
