Yokogawa RAKD Small Metal ROTAMETER RAKD02-D4SS-41NNN- T80NNN
Yokogawa RAKD Small Metal ROTAMETER RAKD02-D4SS-41NNN- T80NNN
Description
The RAKD Rotameter is used for measurement
of liquids and gases and is highly accurate, particularly for low flows and
high pressure applications.
The small metal Rotameter RAKD
differentiates itself from other comparable variable area meters by means of
light and guided float design offering the smallest measurable flow ranges in
the market. RAKD meters can be fitted with a fine control valve and are
designed with horizontal process connections.
An integrated flow controller based on the differential pressure principle,
which allows a constant flow rate to be maintained regardless of any variations
in process pressure, is just one of the many different options available. The
RAKD with either standard or fail safe limit switches is suitable for safety
applications up to SIL level 2. The configuration with valve and controller
reaches SIL level 1.
The RAKD Rotameter combines several benefits of the float principle: a robust
design, reliable measurements, independence of the electrical power supply when
operated as mechanical pointer instruments and an electrical output signal.
They are moreover easy to install and require no maintenance. Both the RAMC and
the RAKD are packaged in an attractive, all-stainless steel housing and boast a
long service life under the harshest industrial conditions.
