> Introduction

Bronkhorst High-Tech B.V., the European market leader in thermal

Mass Flow Meters/Controllers and Electronic Pressure Controllers,

has many years experience in designing and manufacturing precise

and reliable measurement and control devices. With a wide range

of instruments, Bronkhorst High-Tech offers innovative solutions for

many different applications in many different markets. The instru-

ments are made to customers’ specification, in various styles, sui-

table for use in laboratory,

industrial environment, hazardous areas

and production machinery.

> IN-FLOW series for industrial environments

The Mass Flow Meters of the IN-FLOW series are of rugged

design (IP65) for use in pilot and production plants in industrial

environments or even Zone 2 hazardous areas, with optional ATEX

Category 3 approval. Mass Flow Meters can be supplied in ranges

starting from 0,014…0,7 ml

with pressure rating between vacuum and 700 bar. In combination

with control valves, either integrated or separate, Mass Flow

Controllers can be offered up to 10…500 m

> Multi-Bus technology

Bronkhorst High-Tech developed their latest digital instruments

according to the “multi-bus” principle. The main digital pc-board

contains all of the general functions needed for measurement and

control. In addition to the standard RS232 output the instruments

also offer analog I/O. As an option, an integrated interface board

provides DeviceNet

TM

, PROFIBUS DP, Modbus-RTU or FLOW-BUS

protocols. The latter is a fieldbus based on RS485, specifically

designed by Bronkhorst High-Tech for their mass flow metering

and control solutions.

> Mass Flow Controllers for every

application

The control valve can be furnished as integral part of an IN-FLOW

MFC, or as separate component. It is a proportional, electro magnetic

control valve with extremely fast and smooth control characteristics.

With reference to the specific field of application there are different

series of control valves. There is a standard direct acting valve for

common applications, a pilot operated valve for high flow rates, the

so-called Vary-P valve with pressure rating 400 or 700 bar, that can

cope with up to 400 bar ΔP and a bellows valve for applications with

very low differential pressure.
