Industrial Mass Flow Meters and Controllers for Gases
> Introduction
Bronkhorst High-Tech B.V., the European market leader in thermal
Mass Flow Meters/Controllers and Electronic Pressure Controllers,
has many years of experience in designing and manufacturing
precise and reliable measurement and control devices. With a wide
range of instruments and offering innovative solutions for many
d
ifferent applications in a variety of different markets, Bronkhorst
High-Tech is dedicated to customer satisfaction, quality and
sustainability.
> IN-FLOWCTA series for industrial applications
The Mass Flow Meters and Controllers of the IN-FLOWCTA series
are of rugged design (IP65) for use in pilot and production plants
in indusrial environments. The instruments operate on the principle
t
of direct thermal mass flow measurement (no by-pass) and have no
moving parts and no obstructions to the flow path. These features
make IN-FLOWCTA Mass Flow Meters ideal for low pressure drop
applications and for the use on wet or dirty gases. Another advantage
of using this type of sensor is that the instruments measure direct
mass flow, without the need of temperature and pressure correction.
Mass Flow Meters can be upplied in ranges starting from 10…200
s
mln/min up to 50…5000 ln/min Air-equivalent. Mass Flow Control
loops can be ffered, up to 4…200 ln/min Air-equivalent as flow meter
o
with integrated control valve and up to 5000 ln/min with separate
control valve.
> State of the art digital design
The IN-FLOWCTA Mass Flow Meters and Controllers are equipped with
a digital pc-board, offering excellent performance and many features,
at an affordable price. The main digital pc-board on the instrument
contains all of the eneral functions needed for measurement and
g
control. It has nalog I/O-signals and also an RS232 connection
a
as a standard feature. In addition to this there is the possibility
of integrating an interface board with DeviceNet™, Profibus-DP®,
Modbus-RTU or FLOW-BUS protocol.
