Safety
WARNING: READ ALL OF THESE INSTRUCTIONS BEFORE PROCEEDING. ONLY EXPERIENCED PERSONNEL SHOULD INSTALL OR
HANDLE WYATT ENGINEERING METER(S). ANY DAMAGE RESULTING FROM MISHANDLING OR IMPROPER INSTALLATION IS NOT
COVERED BY WARRANTY. FOR WARRANTY DETAILS, REFER TO THE LATEST REVISION OF WYATT ENGINEERING’S TERMS AND
CONDITIONS.
(These instructions are meant as a guide only: They cannot cover every situation and rely on the common sense and expertise of the personnel installing the meter.
Wyatt Engineering is not liable for any damage to the meter, the system, or for personal injury resulting from incorrect installation or the use of these guidelines.)
General:
• Maximum allowed process pressure is given in the specific meter documentation (CE-marked meters have this information on the
nameplate). Over-pressurization due to fluid heating, chemical reaction, explosion, external fire, etc. can cause pressure containment failure.
Other means, therefore, must be taken to prevent over-pressurization.
• Allowable process temperatures are given in the specific meter documentation (CE-marked meters have this information on the nameplate).
Higher or lower temperatures than those considered (due to process fluid, chemical reaction, environment, conduction, convection, etc.) can
cause pressure containment failure. Other means must be taken to prevent temperatures beyond the design range.
• Pressure and temperature ratings are process-based, unless indicated otherwise. Additional loads must be accounted for by the end-user.
• Avoid scraping or scratching the coated surfaces. Touch-up coatings as needed.
Prior to Start-Up:
• Prior to installation, inspect meter(s) for any damage. If a meter appears damaged in any way, contact the local Wyatt Engineering
Representative, or contact Wyatt Engineering directly. Refer to Wyatt Engineering Terms and Conditions for warranty information.
• Meters are not to be used as safety accessories as defined in the Pressure Equipment Directive (PED) 97/23/EC.
• Pipe insulation and/or insert-type meters may not be visible when installed. The end user should identify the presence of the meter in
the pipeline and take precautions to avoid injury and/or discharge if the line is to be disassembled.
• Any risk arising from external fire must be accounted for independent of the Wyatt Engineering meter.
• Determine that the meter is installed with the arrow on the nameplate and on the meter body pointing in the direction of the flow.
• Determine that the meter is properly installed: The venturi meter is a piping component and should be handled with the same safety
precautions. DO NOT HANDLE METER FROM ITS INSIDE.
• Note that the meter(s) must be adequately supported by the adjacent pipe to prevent excess loading on the meter body.
DO NOT USE THE METER AS A PIPE SUPPORT.
• Determine that the piping on both sides of the meter(s) is properly aligned before installation. Refer to ASME Pressure Piping and local
codes for alignment and gap specifications.
• Determine that all pressure connections are proper and are appropriate for the intended service. Meter(s) must be properly connected
(threaded, welded, etc.) to surrounding piping to prevent unsafe discharge during filling and/or operation.
• Determine that no threaded connections are damaged.
• Determine that the meter has been installed in conformance with the Installation Notes included in this manual.
At Start-Up:
• Do not over-pressurize the meter. Refer to Wyatt Engineering documentation for design pressure.
• Do not subject meter to shock pressures or water hammer.
• Do not subject meter to shock temperatures.
• When filling pipeline, bleed-off trapped gases (fluid service) or trapped fluids (gas service).
After Start-Up:
• Do not over-pressurize the meter. Refer to Wyatt Engineering documentation for design pressure.
• Do not subject meter to shock pressures and/or to shock temperatures.
• Wyatt Engineering meters are not designed to withstand stress due to the decomposition of unstable process media.
• CE-marked meters have been evaluated using the ASME Codes with respect to fatigue life. EXCEEDING THE FATIGUE LIFE OF THE
METER MAY RESULT IN SUDDEN METER FAILURE. Contact Wyatt Engineering for cycle information.
• To avoid personal injury, do not touch surface of meter(s) if the process fluid is hotter or colder than room temperature. Allow the
meter(s) to return to room temperature before removing or servicing.
• Conform to “Preventive Maintenance” procedures included in this manual.

Prior to installation, inspect meter(s) for any damage. If a meter appears damaged in any way, contact the local Wyatt
Engineering Representative, or contact Wyatt Engineering directly. Refer to Wyatt Engineering Terms and Conditions for
warranty information.
Do not install the meter immediately downstream of any component that could disrupt the flow pattern. Wyatt Engineering
meters are best suited for installations with symmetric flow. If in doubt, contact the local Wyatt Engineering Representative, or
contact Wyatt Engineering directly for installation guidance.
The meter(s) can be damaged by misalignment, over-tightening, and piping system loads that affect the joint(s) at the
meter.
Handle it from its exterior; do not damage its internal surfaces.
Install meter in the pipeline so that the arrow on the nameplate and on the meter body agrees with the direction of the flow.
Provide necessary clearances as deemed practical for installation, inspection, and maintenance.
Center the meter carefully in the pipe and assure the piping on both sides of the meter(s) is properly aligned before
installation (refer to ASME Pressure Piping and local codes for alignment and gap specifications).
Gaskets must not protrude into the flow or block any pressure taps.
Pipe flanges must be parallel and properly aligned to prevent damage to the meter flange or flanges. Tolerances should be
in accordance with industry standards and local codes.
The meter(s) must be adequately supported by the adjacent pipe to prevent excess loading on the meter body. THE
METER BODY MUST NOT BE USED AS A POINT OF SUPPORT FOR THE PIPELINE. If it is necessary to provide
supports, the unit may be supported at the holding flanges only.
Use standard piping procedures for threaded connections. Insure that threaded connections are not damaged in
installation.
Use standard piping procedures regarding butt-weld and/or socket-weld connections. When welding, use industry-standard
welding procedures and safety precautions. A material test report and data safety sheet for the body material will be
provided upon request. WARNING: A meter can be damaged by excessive heat that may distort materials or compromise
coating systems, leading to unit failure. Use a heat sink or other means to prevent damage from occurring.
Use standard piping procedures regarding gasket type, use, and proper torquing of flange bolts. Do not over-torque bolts.
As a rule, pressure taps should be on the horizontal plane. Refer to contract documents and/or installation instructions of
secondary instrumentation supplier for further details. Ensure that all pressure connections are proper and are appropriate
for the intended service. Meter(s) must be properly connected (threaded, welded, etc.) to surrounding piping to prevent
unsafe discharge during filling and/or operation.
With insert-type meters (weld-in and flange mount), make sure the pipe inside diameter matches that given on the
nameplate. This type of meter extends into upstream and downstream pipe and incorrect pipe size can lead to flow
measurement error and/or damage to the meter (contact the local Wyatt Engineering Representative, or contact Wyatt
Engineering directly with any questions). Install insert-type meter(s) between the pipe flanges with a gasket on each side of
the meter mounting flange. Ensure that each meter is centered inside the bolt circle and tighten the bolts.
With flange-mount insert-type meters, verify that the meter mounting flange is appropriate for the adjacent pipe flanges.
The mounting flange outside diameter should equal the pipe flange bolt circle diameter minus the bolt hole diameter.
With weld-in insert-type meters, verify that the meter mounting block has the same outside diameter as the adjacent pipe.
