Start-Up And Operation - ABB K-MAG 10D1476 Instruction Manual

10D1476 K-MAG MAGNETIC FLOWMETER INSTRUCTION MANUAL
3.0 START-UP & OPERATION
The ABB Series 10D1476 K-MAG Magnetic Flowmeter (which includes the integral or remote Signal
Converter) is precision calibrated at the factory for the values stated on the instrument tags. 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 tag
as shown in Figure 3-1. The basic primary mounted components are identified in Figure 3-2.
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 the Installation Section 2.0. Particular attention should
be paid to the procedure for grounding the liquid passing through the meter. Improper grounding may
result in unsatisfactory performance.
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 K-MAG 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.
