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 Instruments, Inc. 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 Instruments, Inc. as spare parts for the 3152,

process flange, bolts must break back plane of flange
web (i.e. bolt hole), but must not contact module housing.
Use only the RNII 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.
NOTE
For steam service, do not blow down impulse piping through the
transmitter. Flush the lines with the transmitter isolated and refill the
lines with water before resuming measurement.
