1 Foreword
2 Principle of Operation
Welcome to the first edition of Yokogawa’s Rotameter Catalogue.
A Rotameter measures the flow of liquids, gases and steam by using a float inside a tapered tube.
The name Rotameter came from our company, Rota Yokogawa, and has since become the brand
name for variable area flow meters.
The fluid enters at the bottom of the tube and a friction force is generated as the fluid passing
through the annular gap between the float and the tube wall. The float rises until the frictional force,
gravity and buoyancy of the float are all in equilibrium.
Yokogawa has recently celebrated many milestones with highlights being our 35th anniversary of our
first European sales office and the 100th anniversary of Rota Yokogawa. Over the last hundred years
we have built up a reputation for quality, reliability and safety.
Yokogawa has set the standard for the variable area flow meter industry since the introduction of the
Original Rotameter.
The tube is tapered so that the gap between the tube and float is larger at the top to allow a greater
flow to pass through the meter. As gravity works in a vertical orientation so the tube needs to be
vertically oriented.
Rota Yokogawa developed the rotating float which stabilises the position of the float to provide a
more stable flow measurement.
While other suppliers have come and gone, we remain the rock foundation on which you can always rely.
We have selected the most common types of glass & plastic Rotameters and made the ordering
as simple as possible with short models and standard flow ranges. These Rotameters can now be
purchased without sizing from Yokogawa.
Let our 100 years of application experience combined with our broad product offering solve your
measurement problems.

The medium passes through the metering tube from bottom to top and consequently rises the
float until there is an annular gap between the inside surface of the metering tube and the float and
equilibrium of the following forces has been achieved.

3 Rotameter Overview
Trust your own eyes: Rotameter RGC & RQC Series
The flow Tube de mesure is transparent giving you full insight into process and position of
the float – a scale located on the tube indicates the true flow rate.
ROTA developed the form of the rotating float which provides self stabilization. In case of glass and
plastic tubes you can simply view the float position to get a reliable reading of the flow rate from the
top of the float.
If the tube is made of metal the float position is transferred to an outside indicator via a magnetic
coupling. The mechanical nature of the measuring principle provides a flow device that does not
require any electrical power. However, as there are many Applications in process plants that do
require electronic indication and transmission of the measured flow rate, Yokogawa´s Rotameter
portfolio does also provide different solutions.
The Rotameter gets its name from the rotating float which was developed by ROTA to
provide self stabilization.
A Rotameter is truly modular flowmeter. The variety in cones, floats and scales combine
to make the Yokogawa Rotameter suitable for a very wide range of Applications.
The Rotameter principle is one of the oldest and mature principles in flow measurement. This
mechanical principle is as simple as it is reliable.
For tubes made out of glass or plastic the flow is measured by looking at the position of the float
against a scale.

RGC2 series
Glass Rotameter
The tube is made of metal you can not see the float therefore a magnetic coupling is required to
connect the float to an external indicator and optional electronic transmitter.
RGC3 series
Glass Rotameter
A power supply is not needed if only a local indication is required, thereby making Rotameters a very
cost effective flow meter.

•R
otameters must be vertically oriented (flow direction: bottom to top).
• It is absolutely imperative to avoid stress resulting from the connecting pipeline.
• Rotameters must be shielded from pipeline vibration by taking suitable installation measures.
Rotameters must be safeguarded from pulsations in the measured medium.
• Disturbance-free inlet and outlet sections are generally not required. However, in case of gases
measurement a straight, undisturbed length of approx. 5 times the internal pipe diameter is
recommended.
• For gases, in order to avoid measuring errors, it is advisable to select the arrangement such that the
pressure in the Rotameter is as constant as possible and corresponds to the calibration pressure.
The Rotameter is known all over the world
as a reliable measurement instrument and
nowadays is synonymous with the variable
area flowmeter principle. We built this
reputation on customer oriented solutions.
We have the ability to design and manufacture
customer specific solutions made of glass or
plastic.
Most custom-made Rotameters contain
different sizes, special materials and scales or
individual flow ranges.
Once the standard is created it leads to short
response time and high quality.
Customer standards are suited for a
continuous supply of a larger amount of
custom-made Rotameters.
All you need to do is tell us what is necessary
to fulfil your requirements and we will provide
the solution.
Our customers have the opportunity to
develop with us a specific solution for their
application and take advantage of our 100
years experience.
Please contact our Technical Sales Team for
your customized Rotameters.

8 Introduction of Metal Rotameters
Robust and universal: Metal Rotameter Series RAMC
Small in size, big in performance: Metal Rotameter RAKD
Patented blocked float indication system
Retrofitable damping system for gas
applications
Extension for high/low temperature applications
Explosion proof housing available
HART® protocol
Profibus PA
Suitable for SIL 2 applications
Special material like Monel or Hastelloy on
request
What makes this Rotameter different from other
brands is known by many users, who value the
ease of installation and trouble-free operation.
At first glance the instrument looks impressive
with its all stainless steel design. A closer
look reveals a unique patented “blocked float
indication system”. If you value flexibility in a
flowmeter – from the measurement of air to
highly aggressive liquids – in situ replacement
of the indicator without degradation of
performance – the interchangeability of floats –
then the RAMC is for you.
The RAMC combines all the advantages of
the variable area principle with robust design,
reliable measurement, with or without power,
HART® or Profibus PA, culminating in a truly
universal flowmeter for gases, liquids and steam
applications.
Operational safety is of the utmost importance
in any flowmeter, and the RAMC is no exception
– wetted parts are available in a variety of
materials, and intrinsically safe outputs or an
explosion proof housing are available as an
option.
Already in 2005 the well-known independent
organisation Exida® made a hardware
assessment according to the relevant
functional safety standards like IEC 61508.
The assessment consists of a Failure Modes,
Effects and Diagnostic Analysis (FMEDA).
From the FMEDA failure rates are determined
and consequently the Safe Failure Fraction
(SFF) is calculated for the device. The result
of the FMEDA must be considered in order to
determine suitability for a specific Safety Integrity
Level (SIL).
The RAKD is the smaller brother of the RAMC
– is robust in design – for low flows and high
pressure applications.
The RAKD differentiates itself from other
comparable variable area meters by means of
light and guided float design. This feature avoids
oscillations caused by gas compressibility,
leading to very stable measurement. Further
the RAKD offers a wide range of process
connections.
The RAMC with 4…20 mA output or HART®
protocol is suitable for the use in safetyinstrumented systems according to IEC 61508-2
with SIL 1 level due to its unique and patented
blocked float indication system.
The RAMC with local indicator and either
standard or fail-safe limit switches can be used
up to SIL 2 level applications.

With the FMEDA for the RAKD Yokogawa
is the first supplier to become complete to
provide safety excellence to all Metal Rotameter
applications.
The RAKD with either standard or fail safe limit
switches is suitable for safety applications up to
SIL Level 2. The RAKD configuration with valve
and flow controller reaches SIL Level 1.
