Notices regarding EMC
The Rotameter RAGN with option /GR2 – /GR8
is conform to the European EMC Guideline and
fullls the following standards:
DIN EN 61000-4-2: level 3
DIN EN 61000-4-3: level 2
DIN EN 61000-4-4: level 3
DIN EN 61000-4-6: level 2
DIN EN 55011: group 1 / class A
The RAGN with option /GR2 – /GR8 is a class A
product and should be used and installed properly
according to the EMC Class A requirements.
Although the inductive ring sensor has been
designed to resist high frequency electrical
noise, if a radio transceiver is used near the
transmitter or it external wiring, the transmitter
may be affected by high frequency noise pickup.
To test for such effects, bring the transceiver in
use slowly from a distance of several meters from
the transmitter, and observe the measurement
loop for noise effects. Thereafter, always use the
transceiver outside the area affected by noise.

A Rotameter measures the ow of liquids, gases and steam by using a oat inside a conical tube.
The gap between the tube and oat is larger at the top to allow a greater ow to pass through the meter. As gravity
works in a vertical orientation so the tube needs to be vertically oriented.
Rota Yokogawa developed the free rotating oat which stabilises its position in the centre of the cone to provide a
more stable ow measurement.
The medium passes through the metering tube from bottom to top and consequently rises the oat until there is an
annular gap between the inside surface of the metering tube and the oat and equilibrium of the following forces
has been achieved.
Buoyancy / Gravity / Friction force
The Rotameter principle is one of the oldest and mature principles in ow measurement. This mechanical principle
is as simple as it is reliable. The ow is indicated by the top of the oat and can be read from the standard scale on
the metering tube. The RAGN can be equipped with limit switches option /GR2 to /GR8 and /GM1 to /GM5.
All units are calibrated with water or air by the manufacturer. By adjusting the calibration values to the measured
substance’s state of aggregation (density, viscosity), the ow rate scale for each measuring tube can be determined.
When the process conditions have changed the scale is not accurate any longer and the glass tube needs to be
replaced.
1.2 General description
This manual describes installation, operation and maintenance of the RAGN. Please read it carefully before using
this device.
Further, please note that customer features are not described in this manual. When modifying specications,
construction or parts, this manual is not necessarily revised unless it can be assumed that these changes will
impair RAGN functions or performance.
All units are thoroughly tested before shipping. Please check the received units visually to ensure that they
have not been damaged during transport. In case of defects or questions please contact your nearest
YOKOGAWA service centre or sales office. Please describe any defect precisely and indicate model code as
well as serial number.
YOKOGAWA refuses any liability for units which have been repaired by the user without prior consent and do
not meet the specications as a consequence.

3.2 Bistable inductive ring sensor (Option /GR2 –/GR8)
The ring sensor type RI20 is intended for connection to glass Rotameters. It indicates whether the oat is
positioned above or below the sensor.
The oat must have ferromagnetic properties (e.g. a PVDF oat with iron core).
The device is offered into 3 versions:
Type Option Diameter of tube Possible oat (Yokogawa Code)
RI20-10 G /GR2, /GR6 10mm -PD BN
RI20-17 K /GR3, /GR7 17mm -PD CN
RI20-17 G /GR4, /GR8 17mm -PD DN
The RI20 is bistable, i.e. if the oat is below the switch point, current consumption is always < 1 mA and it is
> 2.2 mA, if the oat is above the switch point. After power on or after power fail the RI20 shows
I < 1 mA. To nd the correct oat position the oat has to move once through the RI20.
It is intended for connection to a non-bistable isolation-switch amplier complying with DIN EN 50227
(NAMUR) (e.g. options /Wxx). With its plastic housing and its sealed-in electronic equipment, the RI20
meets the requirements for protection class IP67 and can also be operated safely in aggressive
atmospheres.
The RI20 is maintenance-free.
See chapter 6 "EXPLOSION PROTECTED TYPE INSTRUMENTS” for devices in ATEX version.
3.3 Magnetic contact (Option /GM1 –/GM5)
The limit switch is mounted to a Rotameter type RAGN, if a magnetic oat is used and indicates if the ow
falls below the set limit (MIN-contact) or exceeds the set limit (MAX-contact).
When reaching the switch point the Reed contact with bias by a permanent magnet opens when the oat
enters the alarm range. The Reed contact closes when the oat leaves the alarm range. Opened or closed
the Reed contact remains because of its bistability in its position no matter how far the oat moves away.
Due to the low switch output of the Reed contact (max, 10 VA/(W), max. 0.5 A, max. 230 V AC) a
transformer isolated barrier (e.g. option /W) should be connected to the GM.

4. Installation
4.1 General
Installation:
All packaging material must be removed. The transportation lock for the oat must be removed.
The piping shall be ushed before installing the owmeter. Piping must be dried for gas applications. Rota-
meters must be installed vertically. The ow direction is from bottom to top. Prevent the device from mechani-
cal stress and vibration by aligning and supporting the piping. Avoid large volumes of gas downstream and
upstream of the device, this can cause vibration due to compression. Install the On/Off valve downstream in order
to avoid damage when opening the valve. In case of gas applications, increase the ow pressure slowly. Avoid
pressure surges and temperature shocks to the owmeter at any time.
Refer to the pressure and temperature limits of the device. For owmeters with limit switches please see
chapter 4.3, 4.4 and 4.5.
Further installation hints can be found in VDI/VDE 3513 sheet 3.
Commissioning:
When functioning properly, the oat moves freely in the ow. With oats with notches this can be easily seen
by their rotation. If the oat does not move, please check the installation.
The ow rate can be read directly from the scale on the tube. Refer to the scale mark to which the oat adjusts
its top edge when reading.
Maintenance:
With common applications and normal operating conditions the device is maintenance free. In case of soiling
we recommend to clean the measuring tube by using a bottle brush and soap water. Make sure not to scratch
the measuring tube. If oat or measuring tube show signs of wear and tear, we recommend replacing them.
