Yokogawa Flange Connection 4-20mA Rotameter Flow Meter RAMC
The RAMC variable area flow meter (rotameter) by Yokogawa is a
truly universal flow meter, ideal for measuring air and highly
aggressive liquids in low and high-temperature applications. The
RAMC features a float blockage detection system, all mechanical
design, and easily replaceable components, making it easy to
maintain while delivering high reliability and performance.
Yokogawa’s variable area flow meters adhere to the highest
operational safety standards, and the RAMC is no exception with
wetted parts available in a variety of materials and optional
intrinsically safe outputs.
The RAMC combines all the advantages of the variable area principle
with robust design and reliable measurement. A truly universal
flowmeter for gases, liquids, and steam applications.
All Mechanical Design
The RAMC has a simple, robust design with three common components,
making it ideal for low and high temperature applications, as well
as making it highly reliable and reducing maintenance costs.
Field Replaceable Components
Many components of the RAMC are replaceable, including the float,
scale, eprom (for eletronic transmitters), limit switches, and
housing.
Float Damping System (for Gas Applications)
The float damping system is used in gas applications to avoid
bouncing and putting a lot of wear on the float itself. The system
is retrofittable and exchangeable at any time without requiring the
operator to replace the float, and it can withstand a pressure
maximum of up to 40 bar absolute. With this damping system, no
recalibration is necessary after installation of the damping, and
it is available to add on to old Yokogawa rotameters.
Float Blockage Indication System
This function is used for the electronic transmitter and detects
when fluctuations remain under the preset level, activating an
alarm.
