Introduction

1.1

Scope of this manual

This manual contains general product information, installation and operating instructions and troubleshooting tips for the

FLOW-CONTROL series.

1.2

Intended use

The FLOW-CONTROL is designed to establish and control a constant gas or liquid flow rate in a system where the inlet

pressure is unstable. The fluid in the pressurized system in which the instrument is mounted must be free of solid particles.

The wetted materials are compatible with the following fluids:

·

Air

·

N2 (Nitrogen)

·

O

2

 (Oxygen)

·

CO (Carbon monoxide)

·

Ar (Argon)

·

CO

2

 (Carbon dioxide)

·

CH

4

 (Methane)

·

C

3

H

8

 (Propane)

·

N

2

O (Nitrous oxide)

·

C

4

H

10

 (Butane)

·

H

2

O (water)

For other media, always check compatibility with the wetted parts, before deploying the instrument (see 

Wetted

materials

).

FLOW-CONTROL instruments are 

not

 suitable for use with He (Helium) and H (Hydrogen).

The end user is considered to be familiar with the necessary safety precautions, and to comply with the appropriate

protective measures as described in the Material Safety Data Sheets of the media to be used in the system (if applicable).

Responsibility for the use of the equipment with regard to suitability, intended use, cleaning and corrosion resistance of the

used materials against the processed media lies solely with the end user.

Bronkhorst High-Tech B.V.cannot be held liable for any damage resulting from improper use or use for other than the

intended purpose.
