B Operation Planning
INTRODUCTION
Operation planning is necessary for successful installation. Process
fluid conductivity should be 5 microsiemens/cm (5 micromhos/cm)
or greater. All options available to the Model 8732C Integral
Mount Magnetic Flowmeter System should be carefully reviewed
before selection.
Flowtube site and process fluid characteristics are also important
considerations. Proper flowtube orientation, sizing, and bypass piping
minimize the effects of corrosive, fatty, or abrasive process fluids.
Careful installation reduces start-up delays, facilitates maintenance,
and ensures optimum performance.
SAFETY MESSAGES
Instructions and procedures in this section may require special
precautions to ensure the safety of the personnel performing the
operations. Please read the following safety messages before
performing any operation described in this section.
Explosions could result in death or serious injury:
• Verify that the operating atmosphere of the flowtube and transmitter is
consistent with the appropriate hazardous locations certifications.
• Do not remove the transmitter cover in explosive atmospheres
when the circuit is alive.
• Before connecting a HART-based communicator in an explosive
atmosphere, make sure the instruments in the loop are
installed in accordance with intrinsically safe or non-incendive
field wiring practices.
• Do not make connections to the HART Communicator’s serial port or
NiCad recharger jack in an explosive atmosphere.
• Both transmitter covers must be fully engaged to meet
explosion-proof requirements.
Failure to follow safe installation and servicing guidelines could result in
death or serious injury:
• Make sure only qualified personnel perform these procedures.
• Do not perform any service other than those contained in this manual
unless qualified.
