3.0 OPERATION and START-UP

The ABB Automation Series 3000 Magnetic Flowmeter is precision calibrated at the factory for the
values stated on the instrument tag. If specific values were not specified, the meter is calibrated at
some nominal maximum flow rate and for a 4-20 mA current output span. In either case, the
calibration data is noted on the instrument data tag as shown in Figure 3-1.
There are no operating controls that require field adjustment unless the full scale range setting was
not specified. If a change in the full scale range setting is required, refer to the Instruction Bulletin
supplied with the Signal Converter. If no change is required, the equipment is ready for operation as
received.
Prior to initial system start up, verify that the meter is properly installed; check flow direction, wiring
interconnection and grounding as discussed in Section 2.0 Installation. Particular attention should be
paid to the meter grounding procedures; improper grounding may result in unsatisfactory perform-
ance.
Start flow through the process piping system that includes the meter. Allow a nominal flow through
the pipeline for several minutes to purge entrapped air. The pipeline must be full for accurate flow
measurement.
Apply power to the Magnetic Flowmeter by closing the external switch or circuit breaker; there are no
switches inside of the equipment. Also energize any auxiliary equipment associated with the flow
metering system, such as remote analog recorders, controllers or rate indicators.
Initiate process flow through the pipeline. Flow measurement and concurrent output signal transmis-
sion will commence with flow through the meter. Information concerning operation of the Signal
Converter is provided in the Instruction Bulletin supplied with the Converter.
