Warning and Cautions
General Safety Information
We use caution and warning statements throughout this book to draw your attention to
important information.
Symbol Key
Symbol Symbol Meaning Description
Warning
This statement appears with information
that is important to protect people and
equipment from damage. Pay very close
attention to all warnings that apply to your
application.
Caution/Note
This statement appears with information
that is important for protecting your
equipment’s performance. Read and follow
all cautions that apply to your application.
• Warning! Agency approval for hazardous location installations varies between flow
meter models. Consult the flow meter nameplate for specific flow meter approvals
before any hazardous location installation.
• Warning! Hot tapping must be performed by a trained professional. U.S. regulations
often require a hot tap permit. The manufacturer of the hot tap equipment and/or the
contractor performing the hot tap is responsible for providing proof of such a permit
• Warning! All wiring procedures must be performed with the power O.
• Warning! To avoid potential electric shock, follow National Electric Code safety
practices or your local code when wiring this unit to a power source and to peripheral
devices. Failure to do so could result in injury or death. All AC power connections must
be in accordance with published CE directives.
• Warning! Before attempting any flow meter repair, verify that the line is de-pressurized.
• Warning! Always remove main power before disassembling any part of the
mass flow meter.
WARNING

Disclaimer TM500
• Caution! Before making adjustments to the TM500, verify the flow meter is not actively
monitoring or reporting to any master control system. Adjustments to the electronics will
cause direct changes to flow control settings.
• Caution! All flow meter connections, isolation valves and fittings for hot tapping must have
the same or higher pressure rating as the main pipeline.
• Caution! The flow meter electronics and sensor probe have been manufactured and
calibrated to operate as a unit. The flow meter will not operate properly if parts are replaced
from another meter.
• Caution! Printed circuit boards are sensitive to electrostatic discharge. To avoid damaging
the board, follow these precautions to minimize the risk of damage:
- before handling the assembly, discharge your body by touching a grounded, metal object
- handle all cards by their edges unless otherwise required
- when possible, use grounded electrostatic discharge wrist straps when handling
sensitive components
CAUTION

Receipt of System Components
When receiving a Sierra mass flow meter, carefully check the outside packing carton for damage
incurred in shipment. If the carton is damaged, notify the local carrier and submit a report to the factory
or distributor. Remove the packing slip and check that all ordered components are present. Make
sure any spare parts or accessories are not discarded with the packing material. Do not return any
equipment to the factory without first contacting Sierra Customer Service.
Technical Assistance
If you encounter a problem with your flow meter, review the configuration information for each step
of the installation, operation, and setup procedures. Verify that your settings and adjustments are
consistent with factory recommendations. Installation information can be found in Chapter 2 of this
manual.
If the problem persists, contact Sierra Instruments by e-mail (see inside front cover). For urgent phone
support you may call [phone] between 8:00 a.m. and 5:00 p.m. PST. In Europe, contact Sierra
Instruments Europe at [phone]. In the Asia-Pacific region, contact Sierra Instruments Asia at
[phone]. When contacting Technical Support, make sure to include this information:
• The serial number (marked on the meter's label)
• The firmware version (visible on the display at startup)
• The problem you are encountering and any corrective action taken
• Application information (flow range, gas, pressure, temperature and piping configuration)
Using This Manual
This manual provides information needed to install and operate the Series TM500 Mass Flow Meter.

1. Record inside diameter (ID). Ensure the actual pipe ID
matches the pipe ID shown on the factory calibration
certificate. If IDs do not match, refer to "Pipe Diameter" on
page 61.
2.
Record up/downstream straight-pipe requirements based on
Pipe ID and meter style (insertion or inline). [refer to p. 23]
3.
The Flow Direction Indicator must point in the direction of
flow.
The housing can be rotated for a better view of the meter's
display. Note that the 2 set screws must be loosened before
the housing will turn. [refer to p. 29]
4.
Ensure correct probe depth setting. If using 1 ½" size pipe,
please see note on p. 26.
5.
If needed, the orientation of display can be rotated in 90°
increments for a better view.
[refer to p. 30 for more information]
6. Ensure power wiring [p. 37] and 4-20mA wiring [p. 39 -
p. 40] properly connected. [refer to Wiring section p. 35
for more information]
7.
Ensure remote wiring is correct if remote option ordered.
[refer to p. 46 - p. 48 for more information]
8.
Verify you have the proper output signal wiring
[refer to p. 39 - p. 45 for more information]
9.
Apply power to the flow meter.
10. Check the remaining flow meter settings by accessing the meter settings either through the front panel of the
display or by using the TM500-ViewTM software. Record the settings in the spaces given for items A - F on
the following page.
