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.

1.3 Principle of measurement

1.4 Intended use

damage to the instrument and other material damage.

The steps involved in transport may only be carried out by qualied persons taking into account the safety

instructions.

• Observe the transport instructions on the packaging.

• Observe the below mentioned storage conditions.

• Use only the original packaging.

• The packaging material must be disposed of in accordance with the regulations.

• The transport braces must not be removed until installation.

• Read the chapter “Safety instructions”.

• To avoid any damages, unpack the ow meter only at the installation site.

• Mechanical shocks are to be avoided.

Storage conditions

Please note the following for storage purposes:

• The instrument should be stored in its transport packaging.

• Choose a storage place that meets the following requirements:

• Protection from rain and humidity

• Free of mechanical vibration and shocks

• Ambient temperature between -25 °C – 60 °C

• Atmospheric humidity ranging from 0 – 100 %. Operation above 95 % for longer times is not recommended

Before storing a used ow meter remove any uid from the ow meter and clean it in order to avoid fouling.

Properties of the instrument can change when stored outdoors.

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. Rotameters must be installed vertically. The ow direction is from bottom to top. Prevent the device from mechanical 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.
