Cautions

Caution! Only qualified personnel should install the transducer.

Caution! Do not supply +DC power at the D-connector while using a power supply at

the power jack. Both supplies may be damaged.

Caution! Operating a 12 VDC transducer at 24 VDC will cause equipment damage.

Caution! Only qualified personnel should perform transducer service, calibration or

troubleshooting procedures.

Caution! When using toxic or corrosive gases, purge the unit thoroughly with inert

dry gas before disconnecting from the gas line.

Caution! Printed circuit boards are sensitive to electrostatic discharge. To avoid dam-

aging 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

Series 820 Instruction Manual Chapter 1 Introduction

IM-82-C 1-1

Chapter 1 Introduction

This instruction manual covers the installation, operation and main-

tenance of SierraÕs 820 Series product line including the following

Top-TrakªModels:

· 822 Mass Flow Meter with display (nylon flow body)

· 824 Mass Flow Meter without display (nylon flow body)

· 826 Hi-Flow Meter with display (aluminum flow body)

· 827 Hi-Flow without display (aluminum flow body)

· 822-S Mass Flow Meter with display (stainless steel flow body)

· 824-S Mass Flow Meter without display (stainless steel flow body)

SierraÕs Top-TrakªMass Flow Meters are designed for precise

measurement of gas mass flow. The 820 Series offers a broad range

of sizes and process connections for flexibility and versatility. The

primary standard calibration ensures starting point accuracy and

NIST traceability. The meterÕs 0-5 VDC or 4-20 mA output signal is

provided for recording, data-logging or control. The optional dis-

play reads the mass flow rate directly in engineering units or per-

centage of full scale.

Using This Manual

This manual is organized into four chapters:

· Chapter 1 includes the introduction and theory of operation

· Chapter 2 provides installation and wiring instructions

· Chapter 3 describes transducer operation and features

· Chapter 4 covers maintenance, calibration and troubleshooting

Gas tables and conversion formulas are found in Appendix A.

The product specifications and dimensional drawings are found

in Appendix B.

Throughout this manual, we use the word transducer as a generic

term to represent all models of SierraÕs 820 Series Top-Trak

Mass Flow Meters.

Safety Information

Caution and warning statements are used 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 per-

formance. Read and follow all cautions that ap-

ply to your application.

Receipt of System Components

When receiving a Sierra transducer, 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 com-

ponents are present and match your specifications (as ordered).

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 transducer, review the configu-

ration information for each step of the installation, operation and set

up procedures. Verify that your settings and adjustments are consis-

tent with factory recommendations. Refer to Chapter 4, Trouble-

shooting, for specific information and recommendations.

If the problem persists after following the troubleshooting procedures

outlined in Chapter 4, contact Sierra Instruments by fax or by E-mail

(see inside front cover). For urgent phone support you may call (800)

866-0200 or (831) 373-0200 between 8:00 a.m. and 5:00 p.m. PST.

In Europe contact Sierra Instruments bv at +31 20 6145810. When

contacting Technical Support, make sure to include this information:

· the flow range, serial number, Sierra order number and

model number (all marked on the transducer nameplate)

· the problem you are encountering and any corrective action

taken

· application information (gas, pressure, temperature, pipe and

fitting configuration)

Top-Trak Features

Standard Top-Trak Mass Flow Meters require a 12 to 15 VDC exter-

nal power source (24 VDC input power optional). The transducerÕs

0 to 5 VDC output signal allows for flow recording, data-logging or

control. A 4 to 20 mA output signal is optionally available. Input

power and output signal connections are made via the 9-pin sub-type

D-connector located on the side of the transducer. An additional input

power jack is located just below the D-connector. (It is important to

connect input power at only one location.)

The transducer shown below is a typical example of a 822 Series

Top-Trak Mass Flow Meter. Other models may vary slightly in their

appearance but are operationally equivalent.

The 820 Series Flow Sensing Principle

The operating principle of Top-Trak transducers is based on heat

transfer and the first law of thermodynamics. During operation

process gas enters the instrumentÕs flow body and divides into two

flow paths, one through the sensor tube, the other through the lami-

nar flow element bypass. The laminar flow bypass generates a pres-

sure drop, P1ÐP2, forcing a small fraction of the total flow to pass

through the sensor tube (m1).

Figure 1-2. Flow Paths through the Transducer

Two resistance temperature detector (RTD) coils around the sensor

tube direct a constant amount of heat (H) into the gas stream. In ac-

tual operation, the gas mass flow carries heat from the upstream coil

to the downstream coil. The resulting temperature difference (DT) is

detected by the RTD coils and gives the output signal. Since the

molecules of the gas carry away the heat, the output signal is linearly

proportional to gas mass flow.
