IMPORTANT CUSTOMER NOTICE- OXYGEN SERVICE
Unless you have specifically ordered Sierra’s optional O2cleaning, this flow meter may not be fit for
oxygen service. Sierra Instruments, Inc., is not liable for any damage or personal injury, whatsoever,
resulting from the use of Sierra Instruments standard mass flow meters for oxygen gas. You are
responsible for cleaning the mass flow meter to the degree required for your oxygen flow application.
However, some models can only be properly cleaned during the manufacturing process.

Warnings and Cautions
Note and Safety Information
We use caution and warning statements throughout this book to draw your
attention to important information.
Warning!
Caution!
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.
This statement appears with
information that is important for
protecting your equipment and
performance. Read and follow all
cautions that apply to your application.
Warning!
Consult the flow meter nameplate for specific flow meter approvals before any hazardous location
installation.
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.
All flow meter connections, isolation valves and fittings for cold/hot tapping must have the same or
higher pressure rating as the main pipeline.
For insertion flow meter installations, an insertion tool must be used for any installation where a flow
meter is inserted under pressure greater than 50 psig.
To avoid serious injury, DO NOT loosen a compression fitting under pressure.
To avoid potential electric shock, follow National Electric Code or your local code when wiring this unit
to a power source. Failure to do so could result in injury or death. All AC power connections must be in
accordance with published CE directives. All wiring procedures must be performed with the power off.
Before attempting any flow meter repair, verify that the line is not pressurized. Always remove main
power before disassembling any part of the mass flow meter.

4
Caution!
Calibration must be performed by qualified personnel. Sierra strongly recommends that you return your
flow meter to the factory for calibration.
In order to achieve accurate and repeatable performance, the flow meter must be installed with the
specified minimum length of straight pipe upstream and downstream of the flow meter’s sensor head.
When using toxic or corrosive gases, purge the line with inert gas for a minimum of four hours at full gas
flow before installing the flow meter.
For insertion flow meter installations, the sensor alignment pointer must point downstream in the
direction of flow.
The AC wire insulation temperature rating must meet or exceed 85°C (185°F)
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 6 of this manual.
If the problem persists after following the troubleshooting procedures outlined in
Chapter 6 of this manual, contact Sierra Instruments by fax or by E-mail (see
inside front cover). For urgent phone support you may call [phone] or
[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 + 8621 5879 8521. When contacting Technical Support, make
sure to include this information:
 The flow range, serial number, and Sierra order number (all
marked on the meter nameplate)
 The software version (visible at start up)
 The problem you are encountering and any corrective action taken
 Application information (gas, pressure, temperature and piping
configuration)

Chapter 1 Introduction
240i/241i HART Introduction
This document describes the function and operation of the optional HART interface for the
Sierra Instruments flow meter. The InnovaMass 240i/241i complies with HART Protocol
Revision 7.4. This document specifies all the device specific features and documents HART
Protocol implementation details (e.g., the engineering unit codes supported). The
functionality of the InnovaMass (field device) is described sufficiently to allow its proper
application in a process and its complete support in HART capable host applications.
This manual is designed to complement other documentation (e.g., the InnovaMass 240i/241i
product manual) by providing a complete, unambiguous description of the InnovaMass
240i/241i from a HART Communication perspective. It is also intended to be a technical
reference for HART capable host application developers, system integrators and
knowledgeable end users. This manual provides functional specifications used during Field
Device configuration, maintenance and testing. This document assumes the reader is familiar
with HART Protocol requirements and terminology.
Note
In this manual 240i/241i HART refers to product models 240i and 241i.

Process Interface
Sensor Input
The InnovaMass 240i/241i HART can have up to 3 three internal sensors —a piezo
electric Vortex shedding sensor, a precision platinum temperature sensors and one
absolute pressure transducer sensor.
Host Interface
4-20 mA Flow Out:
The active two-wire 4-20 mA current loop is connected on the (+) and (-) wires. HART
communication is supported on this loop. At least one 250 ohm resistor will needed in the
loop to access the HART signal.
The InnovaMass is powered from 24 VDC +/- 10% (1.1A load, maximum)

Device Description Files
The 240i/241i Series meters support two Device Description (DD) Files: PC interface
programs and 475 Field Communicators.
The following DD files are for using PC interface programs
0201.fm8
0201.im8
0201.sym
shapes.txt
The following DD files are for using 475 Field Communicator

Device Status
Bit 0 (PV out of limits) is set if the PV value is exceeding the sensor limits.
Bit 1 (non-PV out of limits) is set if the temperature or voltage measurements value is
exceeding their sensor limits
Bit 2 (analog output saturated) is set if the loop current tries to exceed the over and under
range limits of 3.8 and 20.5 mA. The digital value will continue,until the sensor limit is
reached.
Bit 3 (analog output fixed) is set if the device is in multi-drop mode or in fixed current mode
for testing purposes.
Bit 4 (more status available) is set whenever any alarm or failure is detected. Command #48
gives further detail (see Table 12).
Bit 5 (cold start) is set at power-up.
Bit 6 is not used
Bit 7 (field device malfunction) is set when there is a permanent failure of the device. See
Table 12
