2000 microEFM for Foundation™ Fieldbus
When liquid measurement is the goal and pressure inputs are not required, simply purchase the Scanner 2000
without the MVT and mount it directly to a liquid turbine meter, then install an RTD in the ow line for
temperature compensation. The Scanner 2000 uses algorithms based on AGA-7 principles to give accurate
measurement of API liquids and other generic liquids..
Hardware
The standard Scanner 2000 microEFM features an enclosure with two conduit openings for signal cable, a
large LCD, a three-button keypad, integral multi-variable transmitter with integral vent plugs, and a lithium
double-D cell battery pack (Figure 1.1, page 8). MVTs are available in NACE and non-NACE models, and
with bottom ports (gas measurement) and side ports (liquid and steam measurement). Alternatively, Scanner
2000 congurations are available for direct connection to a turbine meter, which is ideal for applications that
do not require pressure measurement.
The Scanner 2000 microEFM is powered by a customer-provided FISCO-certied power supply. The internal
lithium battery pack provides backup power.
