WARNING
Electrical shock can result in death or serious injury.
•
Avoid contact with the leads and terminals.
Process leaks could result in death or serious injury.
•
Install and tighten all four flange bolts before applying
pressure.
•
Do not attempt to loosen or remove flange bolts while
the transmitter is in service.
Replacement equipment or spare parts not approved by
Rosemount Nuclear for use could reduce the pressure
retaining capabilities of the transmitter and may render
the instrument dangerous or adversely impact its
qualified status.
•
Use only components supplied with the Rosemount
3152, 3153 or 3154 transmitter or designated by
Rosemount Nuclear as spare parts for the 3152, 3153
or 3154.
Improper assembly of mounting bracket to traditional
process flange can damage sensor module.
•
For safe assembly of bracket to transmitter traditional
process flange, bolts must break back plane of flange
web (i.e. bolt hole), but must not contact module
housing. Use only the approved bolts supplied with
the bracket.
GENERAL
CONSIDERATIONS
Measurement accuracy depends upon proper installation of
the transmitter and its associated impulse piping and valves.
Mount the transmitter close to the process and use a minimum
of piping to achieve best accuracy. For flow measurement,
proper installation of the primary element is also critical to
accuracy. Also, consider the need for easy access, personnel
safety, practical field calibration and a suitable transmitter
environment. Transmitter installation should minimize the
effects of temperature gradients and fluctuations, and avoid
vibration and shock during normal operation.
MECHANICAL
CONSIDERATIONS
This section contains information you should consider when
preparing to mount the transmitter. Read this section carefully
before proceeding to the mechanical installation procedure.
Proper installation is mandatory to assure seismic
qualification.
WARNING
Do not attempt to loosen or remove flange bolts while the
transmitter is in service.
