1 Planning
Topics covered in this chapter:
• Installation checklist
• Best practices
• Power requirements
• Other installation considerations
• Recommended installations for the HFVM
• Perform a pre-installation meter check
1.1 Installation checklist
Verify the contents of the product shipment to confirm that you have all parts and
□
information necessary for the installation.
Verify that the meter calibration-type code corresponds to the pipe size. If it does
□
not, measurement accuracy may be reduced due to the boundary effect.
Make sure that all electrical safety requirements are met for the environment in
□
which the meter will be installed.
Make sure that the local ambient and process temperatures and process pressure
□
are within the limits of the meter.
Make sure that the hazardous area specified on the approval tag is suitable for the
□
environment in which the meter will be installed.
Make sure that you will have adequate access to the meter for verification and
□
maintenance.
Verify that you have all equipment necessary for your installation. Depending on
□
your application, you may be required to install additional parts for optimal
performance of the meter.
Planning
1.2 Best practices
The following information can help you get the most from your meter.
• Handle the meter with care. Follow local practices for lifting or moving the meter.
• If you have an HFVM with calibration code B (viscosity and density calibration),
perform a Known Density Verification (KDV) check of the meter prior to installing
the meter.
• For the DLC-coated tines, always fit the protective cover over the tines when the
meter is not in use. The tine coating is not resistant to impact damage.
• Always store and transport the meter in its original packaging.
• Do not use liquids that are incompatible with the materials of construction.

Planning
• Do not expose the meter to excessive vibration (greater than 0.5 g continuously).
Vibration levels in excess of 0.5 g can affect the meter accuracy.
• For optimal performance of the meter, ensure that operating conditions correspond
to the meter calibration-type code and boundary.
• Ensure that all piping connections conform to the local and national regulations and
codes of practice.
• Follow fluid velocity guidelines and install the tines vertically for side insertion.
• Properly tighten the transmitter housing cover after wiring to maintain ingress
protection and hazardous area approvals.
• After installation, pressure test the meter and the associated pipework to 1½ times
the maximum operating pressure.
• Install thermal insulation in the meter, the inlet, and the bypass-loop pipeline to
maintain stable temperatures. The thermal insulation should cover the process
connection.
1.3 Power requirements
Following are the DC power requirements to operate the meter:
• 24 VDC, 0.65 W typical, 1.1 W maximum
• Minimum recommended voltage: 21.6 VDC with 1000 ft of 24 AWG (300 m of
0.20 mm2) power-supply cable
• At startup, power source must provide a minimum of 0.5 A of short-term current at
a minimum of 19.6 V at the power-input terminals.

1.4 Other installation considerations
Numerous external factors can affect the meter's successful operation. To ensure that your
system works correctly, consider the factors covered in this section when designing your
installation.
1.4.1 Boundary effect
4 Micro Motion Heavy Fuel Viscosity Meter
Boundary effect refers to the distortion in the wave forms in the process fluid that are caused by reflections from the pipe wall. If the pipe wall is within the meter's effective measurement region, the boundary effect produces measurement inaccuracy.

C. Sensitive, or effective, region
The factory calibration compensates for the boundary effect. The meter can be calibrated
for 2-inch, 2.5-inch, or 3-inch pipe. If the meter is installed in a pipe that does not match
the calibration size, the compensation will be inaccurate, and process measurement will
be inaccurate.
Verify that the meter was calibrated for the pipe size you plan to use.
1.4.2 Flow rates
Maintain constant flow rates and velocities that are within the limits specified for the
meter. The fluid flow provides a steady heat flow into the meter installation, and the flow
rate influences the self-cleaning of the meter tines, the dissipation of bubbles, and the
solid contaminants around the meter.
If you install the meter in a bypass configuration (such as in a flow-through chamber), use a
pressure drop, pitot scoop, or a sample pump to maintain flow. When using a sample
pump, place the pump upstream from the meter.
