Warnings 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 TM100

• Caution! Before making adjustments to the TM100, 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 and troubleshooting information can be found in

the Chapter  (Installation) and Chapter  Maintenance sections of this manual.

If the problem persists after following the troubleshooting procedures outlined in Chapter  of this

manual, contact Sierra Instruments by e-mail (see inside front cover). For urgent phone support you

may call () - between : a.m. and : p.m. PST. In Europe, contact Sierra Instruments

Europe at +  . In the Asia-Paciﬁc region, contact Sierra Instruments Asia at + 

. When contacting Technical Support, make sure to include this information:

• The serial number (marked on the meters 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

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 p. 59.

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]

Ensure correct probe depth setting. If using 1 ½" size pipe,

please see note on p. 26.

Open the housing. If needed, the orientation of display can

be rotated in 90° increments for a better view.

[refer to p. 28 for more information]

6. Ensure power wiring [p. 37] and 4-20mA wiring [p. 38

- p. 39] are properly connected. [refer to Wiring section p.

35 for more information]

Verify the output signal wiring based on model type (Pulse/

Alarm or communication protocol) [refer to Wiring section p.

38 for more information]

Apply power to the ﬂow meter.

8. Check the remaining ﬂow meter settings by accessing the meter settings either through the front panel of

the display or by using the TM100-ViewTM Software. Record the settings in the spaces given for items A - F

on the following page.

Use the table below as a guide while using the worksheet on the next page to record your notes.
