Scanner ® 2000 microEFM Section 2
Measuring Uncompensated Liquid via a Turbine Meter
Best Practices
The Scanner 2000 microEFM calculates uncompensated liquid flow through a turbine meter in accordance
with API MPMS, Chapter 5, Section 3, Measurement of Liquid Hydrocarbons by Turbine Meters. For
optimum performance, ensure that the turbine and Scanner 2000 installation complies with the industry
recommendations listed below:
• Install the turbine flowmeter in the meter run such that there are at least 10 nominal pipe diameters upstream
and five nominal pipe diameters downstream of the meter. Both inlet and outlet pipe should be of
the same nominal size as the meter.
• Straightening vanes are recommended for eliminating swirl conditions. If used, they should be installed
five pipe diameters upstream of the meter.
Installation Procedure—Direct Mount to a Turbine Meter (CSA Compliant)
A Scanner 2000 without the MVT bottomworks can be mounted directly to a liquid turbine meter for
measuring liquid (Figure 2.14). A pipe adapter and union are attached to the Scanner, allowing a direct
connection to the turbine meter.

To connect the Scanner 2000 to a liquid turbine meter using this method, perform the following steps:
1. Position the Scanner 2000 above the flowmeter.
2. Plug the Scanner 2000 cable connector into the magnetic pickup of the turbine meter and hand-tighten the
knurled nut on the connector.
3. Screw the Scanner 2000 onto the flowmeter threads surrounding the magnetic pickup with the display facing
the desired direction.
4. Tighten all sections of the pipe union.
CAUTION Do not use Teflon ® tape on the threads of the union, adapter, or pipe plugs. Use of
Teflon ® tape will void the explosion-proof rating of the instrument.
