NOTICE
Damage hazards. Failure to follow these instructions could resulting damage or destruction of
equipment.
• The sensor liner is vulnerable to handling damage. Never place anything through the
sensor for the purpose of lifting or gaining leverage. Liner damage may render the
sensor inoperable.
• Metallic or spiral-wound gaskets should not be used as they will damage the liner face of
the sensor. If spiral wound or metallic gaskets are required for the application, lining
protectors must be used. If frequent removal is anticipated, take precautions to protect
the liner ends. Short spool pieces attached to the sensor ends are often used for
protection.
• Correct flange bolt tightening is crucial for proper sensor operation and life. All bolts
must be tightened in the proper sequence to the specified torque specifications. Failure
to observe these instructions could result in severe damage to the sensor lining and
possible sensor replacement.
• In cases where high voltage/high current are present near the meter installation, ensure
proper protection methods are followed to prevent stray electricity from passing
through the meter. Failure to adequately protect the meter could result in damage to
the transmitter and lead to meter failure.
• Completely remove all electrical connections from both sensor and transmitter prior to
welding on the pipe. For maximum protection of the sensor, consider removing it from
the pipeline.
• Do not connect mains or line power to the magnetic flowtube sensor or to the
transmitter coil excitation circuit.
