Restriction on Use of Radio Transceiver

IMPORTAN

Although the transmitter 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.

1. INTRODUCTION

1.3 General description

This manual describes installation, operation and maintenance of the RAKD. Please read it carefully before using this device. Further, please note that customer features are not described in this manual. When modifying specifications, construction or parts, this manual is not necessarily revised unless it can be assumed that these changes will impair RAKD 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 com. no. number. YOKOGAWA refuses any liability for units which have been repaired by the user without prior consent and do not meet the specifications as a consequence..

1.4 Principle of measurement

The RAKD is a Variable Area Flow Meter for volume and mass measurements of gases and liquids. A float, whose movement is nearly independent of viscosity is guided concentrically in a specially shaped cone. The position of the float is transferred magnetically to the indicator, which shows the measurement values by a pointer on a scale. The indicator can be equipped with limit switches and an electronic transmitter.

F10.EPS

Fig. 1.1

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 flow rate scale for each measuring tube can be determined.

2. PRECAUTIONS

2. Precautions

2.1 Transportation and Storage

Before transporting the unit, it is recommended to fix the float with a card-board strip in the same way as when shipped from factory. Prevent foreign objects from entering the tube (e.g. by covering openings). To protect the unit and especially the tube’s interior from soiling, store it only at clean and dry locations

2.2 Installation

Ambient temperature and humidity of the installation location must not exceed the specified ranges. Avoid locations in corrosive environments. If such environments are unavoidable, ensure sufficient ventilation. Although the RAKD features a very solid construction, the instrument should not be exposed to strong vibration or impact stress. Please note that the RAKD is magnetic sensing system can be influenced by external inhomogeneous

magnetic fields (such as solenoid valves). Alternating magnetic fields (≥ 10Hz) as well as homogeneous, static

magnetic fields (in the area of the RAKD), like the geomagnetic field have no influence. Asymmetric ferromagnetic bodies of considerable mass (e.g. steel girders) should be kept at a distance of at least 250 mm from the RAKD. To avoid interference, the distance between two adjacent RAKDs must be at least 300 mm. Do not expose the unit to pressures higher than the indicated maximum operating pressure (refer to specifications) Make sure that wetted parts are resistante against the process medium. Ambient- and process-temperature may exceed specified maximum values. Note the temperature curves in fig. 2-1 and chapter 7 "Technical data". The Rotameter must be mounted verticaly. The flow direction is upwards.

IM 01R01B30-00E-E

4th edition, April 2007

2. PRECAUTIONS

Check movability of the float (5)* by watching the pointer. The pointer should follow the movement of the float. If this is not the case, float and measuring tube (1;21) should be cleaned. Check the movability of the pointer by careful moving it with your fingers and watching whether it responds to the scale value. If it does not work properly, the mechanical display unit (14) must be changed.

To avoid damage of the float and of the stopper do not use magnetic valves. In the phase of start up increase

the flow slowly to the desired flow rate.If a sudden rise of the pressure can not be avoides (with use of magnetic valves) the flow must be limited to the maximum used value (e.g by valve).

*: Position numbers are illustrated in the explosion drawings in chapter 6.

IM 01R01B30-00E-E 4th edition, April 2007

3. INSTALLATION

3. Installation

3.1 Installation in the pipeline

The pipe has to be so stabilized that vibrations on the pipe are avoided. Additional recommendations can be found in guideline VDI/VDE 3513 sheet 3.

If pollution of the metering tube may appear a bypass-pipe is recommended, which permits the removal (see. chapter 6 “maintenance”) of the Rotameter for cleaning without interruption of the flow.

Before installing the Rotameter, make sure there are no parts of packing or securing inside the Rotameter. It has to be taken care at the connection of units with internal thread that no residues of the sealing compound

come into the tube (e.g. remains of the PTFE sealing compound).

In case of devices without valve but with process connection internal thread the float shaft of tubes with cone 44 and bigger sizes may move into the range of the threaded joint. Keep attention not to bend the guide bar when screwing up the connection. The inner diameter of the connector must be at least 8 mm for cone sizes 44 - 51 resp. 10 mm for cone sizes 52 and 53.

To avoid float bouncing in case of gas applications, attend to VDI/VDE 3515 sheet 3. For devices without valve use a throttle either in the inlet or outlet (to install at that side with the bigger volume). For installation of several instruments in parallel tubes take care that the distance between the middle axis is at least 300 mm to avoid magnetic influence. The distance to other ferritic material should not be less than 250 mm. Take care that the strength of external magnetic fields is approximately 0 mT.

3.2 Wiring

3.2.1 Connecting diagrams

Please regard the drawings of this chapter.

RAKD with electrinic transmitter or with limit switches have one or two Quickon connectors at the rear. In the connecting diagramst he lower one is named "S" and the upper une "T". Not used connector positions are closed with a blind plug.

The following table shows the connections for the respective equipment configuration.
