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 igh-Tech offers nnovative olutions for

table for use in laboratory, industrial environment, azardous areas
and production machinery.
>t 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
e
nvironments 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 mln/min up to 11000 m3n/h air-equivalent,
with pressure rating between vacuum and 700 bar. In ombination
c
with control valves, either integrated or separate, Mass Flow
Controllers can be offered up to 10…500 m3n/h air-equivalent.
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.
>t Multi-Bus technology
>t General IN-FLOW features
Bronkhorst High-Tech developed their latest digital instruments
a
ccording 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 DeviceNetTM, 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.
