Metal Variable Area Meter RAKDThe 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.
