1. INTRODUCTION
1.3 General description
This manual describes installation, operation and maintenance of the RAMC. 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 RAMC 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 specifications as a consequence.
1.4 Principle of measurement
The RAMC 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 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.
Indication units can be exchanged without impairment of precision. However, the scale for the tube must be
mounted on the new indicator (and in case of an electronic transmitter the calibration EEPROM, too).

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 RAMC features a very solid construction, the instrument should not be exposed to strong
vibration or impact stress.
Please note that the RAMC’s 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 RAMC), 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 RAMC.
To avoid interference, the distance between two adjacent RAMCs must be at least 300 mm.
2.3 Pipe connections
Ensure that the bolts of the flanges are tightened properly and that the gaskets are tight.
Do not expose the unit to pressures higher than the indicated maximum operating pressure (refer to
specifications).
While the system is pressurized the flange bolts must not be tightened or loosened.

3. INSTALLATION
3. Installation
3.1 Installation in the pipeline
Be sure to remove the transport lock card-board strip from the measuring tube. Check that no cardboard
remains in the tube.
The RAMC flow rate meter must be installed in a vertical pipeline, in which the medium flows upwards. The
vertical position has to be checked at the outer edge of the flanges. Bigger nominal diameters (DN80/DN100)
require straight pipe sections of at least 5D in front and behind the RAMC.
The nominal diameter of the RAMC should correspond to the nominal diameter of the pipeline.
To avoid stress in the connecting pipes, the connecting flanges must be aligned in parallel and axial direction.
Bolts and gaskets have to be selected according to the maximum operating pressure, the temperature range
and corrosion conditions. Centre gaskets and tighten nuts with a torque appropriate for the pressure range.
If contamination or soiling of the RAMC is to be expected, a bypass should be installed to allow the removal of
the instrument without interruption of the flow.
Please read also chapter 2-2. For further instructions on installation please refer to VDI/VDE3513.
3.2 Wiring of electronic transmitter (-E, -H) and limit
switches (/K_)
Please regard the drawings on the following pages.
On the rear of the RAMC are two cable glands for round cables with a diameter of 6 to 9 mm (not for Ex-dtype option /KF1). Unused glands must be closed with a blind plug M16x1.5.
For wiring of RAMC with option /KF1 see chapter 10.6.2
Wires should not be bent directly at terminal screws. Do not expose wires to mechanical pressure. Wires must
be arranged according to common installation rules, especially signal and power lines must not be bundled
together.
The RAMC terminals accept wires with a maximum sectional area of 1.5 mm2.
Measuring and indicating instruments, connected in series to the output of the electronic transmitter, must not
exceed a load impedance of
RL = (U - 13.5 V) / 20 mA — for 2-/3-wire RAMCs or 500 Ω for 4-wire RAMCs.
2- or 3-wire units are connected to the terminals marked “+”, “-” and “A” of the power connector.
For 2-wire instruments the terminals “-” and “A” have to be shorted with a jumper. Take care not to loose that
jumper when mounting wires.
Wiring inside the case should be kept as short as possible to avoid that moving parts are blocked.
Attention: Hints for Unit Safety (according DIN EN 61010)
- Heed the nominal voltage indicated on the scale.
- The electrical connections have to be executed according to VDE0100 “Errichten von Starkstromanlagen
mit Nennspannungen bis 1000 V” (Installation of high current assemblies with nominal voltages of up to 1000 V)
or equivalent national regulations.
- For units with a nominal voltage of 115 V or 230 V the correspondingly marked terminal has to be
connected to protective earth (PE).
- Units with a nominal voltage of 24 V may only be connected to a protected low voltage circuit (SELV-E
according to VDE0100/VDE 0106 or IEC 364/IEC 536).
- The RAMC housing must be grounded to ensure electro-magnetic interference protection. This can be
done by grounding the pipeline.
- This unit does not include a power switch. Therefore, a switch has to be prepared at the installation
location in the vicinity of the unit. The switch should be marked as the power separation switch for the
RAMC.

4. START OF OPERATION
4. Start of operation
4.1 Hints on flow rate measurement
The measured fluid should neither consist of a multi-phase mixture nor contain ferrite ingredients or large
solidmass particles.
The RAMC scale is adjusted to the state of operation/aggregation of the measured fluid by the manufacturer. If
the state of operation changes, it might become necessary to establish a new scale. This depends on several
factors:
- If the RAMC is operated in the given viscosity independent range, only the density of the float as well as the
operational density of the previous and new substance have to be considered. In case the operational
density only changes marginally (≤ 0.5%), the present scale can be used.
- If the RAMC is operated outside the given viscosity independent range, the viscosities at the previous and
new state of operation as well as the mass and diameter of the float have to be taken into account.
To establish a new scale, please refer to the folder “Anweisung zur Skalenumrechnung” (Instructions for
Scale Conversion) as well as the conversion table or order a new scale.
4.2 Pulsation and pressure shock
Pressure shock waves and pulsating flow influence measurement considerable or can destroy the meter.
Surge conditions should be avoided. (→ open valves slowly, raise operating pressure slowly)
If float bouncing occures in gases increase the line pressure until the phenomena stop. If this is not possible
provide the float with a damper. A damping kit is available as spare part.
4.3 Start of operation of electronic transmitter
Ensure that the device has been connected correctly according to section 3-2 and that the used power supply
meets the requirements indicated on the scale.
Switch on the power supply.
The digital display gives the totalizer value in the measuring unit, indicated on the right side of the display.
The RAMC is now ready for operation.
Unit graduation, measuring unit, damping, etc. can be adjusted by an operating menu (refer to section 6.2). In
case of an error, the bars beneath the 8 digits of the display will flash. The corresponding error message can
be checked using the operating menu and then taking the appropriate counter measures (refer to section
6-2-8 “Error Messages”).
The transmitter has been prepared and calibrated according to the model code as a 2-, 3- or 4-wire unit.
In 2-wire units, a jumper connects “A” and “-”. When switching from a 2- to a 3-wire configuration, this jumper
should be removed. The current output should then be adjusted as explained in section 6-2-6.
When changing from a 3- to 2-wire configuration, the jumper should be set in place, and the current output
has to be adjusted according to section 6-2-6.

5. LIMIT SWITCHES (OPTION /KN)
5.
The optional limit switches are available as maximum or minimum type switches. They are proximity switches
according to EN 60947-5-6 (NAMUR). Maximal two switches can be installed. The option (/Wnn) includes the
respective transmitter relay.
These switches have been specified for hazadous area. However, the transmitter relay has to be installed
outside any hazadous area.
The limit switches are connected to the transmitter relays as indicated in section 3-2.
The terminals for the limit switches are on a small board on top of the transmitter case.
The MIN-MIN and MAX-MAX functions (refer to option /K3) have been integrated at the factory as MIN-MAX
switches in the RAMC. The MIN-MIN or MAX-MAX function is set by adjusting the switching direction of the
transmitter relay. The following table shows the assignment:

Note: switching direction “normal” means : inversion “OFF”
“inverted switching” means : inversion “ON”.
When using limit switches as a safety option, the switching directions for all combinations should be set to
normal (inversion “OFF”) on the transmitter relay.
To ensure functional safety the transmitter relay has to be applied as protection technology.
Please notice chapter 9.3 "Standard specifications".
For questions regarding protection technology, please consult your YOKOGAWA service centre.

6. ELECTRONIC TRANSMITTER (-E)
6. Electronic Transmitter (-E)
6.1 Operation principle
The position of the float is magnetically transferred to a magnetic follow up system. The position angle of this
magnetic rocker is detected by magnet sensors. A micro controller determines the angle by means of a
combining reference value table in the memory and calculates the flow rate by the angle with calibration and
operation parameters the calibration EEPROM. The flow rate is given as a current, either 0-20 mA or 4-20mA,
and, in addition, indicated on the digital display (refer also to section 6-2). The electronic transmitters have
been electronically calibrated before shipping and, therefore, are mutually exchangeable.
Calibration data of the metering tube as well as customer specific data are entered into a calibration EEPROM,
inserted on the board. This calibration EEPROM and the indication scale are assigned to the respective
metering tube.
When replacing an indicator (e.g. because of a defect) the scale and calibration EEPROM of the old unit have
to be inserted in the new unit. Then, no calibrations or adjustments are necessary.
If an indicator with electronic transmitters is installed to a new metering tube, the calibration EEPROM of that
tube has to be inserted into the transmitter and the indicator scale for that particular tube has to be mounted.
A change in the fluid data (e.g. specific gravity, pressure, etc.) requires the preparation and mounting of a new
calibration EEPROM and scale.
Normally the range of the current output is equal to the rounded measuring range of the tube (end value on
scale). The customer can position the 20 mA point between 60% and 100% of the end value on scale. The set
of the 20 mA point is shown on the scale (refer to Fig. 1-4). The flow cut off is positioned at 5% of the end
value.
Below 5% flow the current output shows 0 mA (4 mA).
6.2 Parameter setting
The displays allows indication of various parameters:
- Flow rate (8 mass or volume units in combination with 4 time units)
- Counter (8 mass or volume units)
- Flow rate indication in percent
- Special functions:
- Setting of different damping times
• Switching of current output 0-20 mA / 4-20 mA or vice versa
• Indication of error messages
• Manual calibration
• Service functions
• Detection of float blockage
The setting of these parameters is done by two buttons.

The buttons access three functions:
- upper button ( ↑ ) : Exit setting mode
- lower button ( → ) : Scroll through menu/selection of parameters
- both buttons ( ↑ + → ) = Enter : Entering parameters/selecting setting mode
If no button is pressed for one minute while the operating menu is active, the indication reverts to the
measuring indication. This does not apply to subfunctions F32, F33, F52, F63.
For indication of volume or mass values at maximum 6 digits in front of the decimal point and 7 decimals are
used. This format allows an indication range for flow rates from 0.0000001 uni/time to 106000 unit/time. Flow
rate values exceeding 106000 are shown as ‘————’ on the display. In this case the next bigger flow rate
unit (next smaller time unit) has to be selected.
For the indication of totaliser values 8 digits are used at maximum of which 7 digits can be assigned for
decimal values. The decimal point setting is determined by selecting the unit. Therefore, possible totaliser
offsets are:
Unit *1
Unit *1/10
Unit *1/100
The totaliser counts up to 99999999 or 9999999.9 or 999999.99 and is reset to zero.
The next page shows the operating menu.
The following describes selection and execution of functions.
