5.3.1 Connection of the Multi-Power unit
Optionally, beside an internal or external battery, the 6500W + IMT65W can be connected to an
external Multi-Power unit for mains power and/or DC power operation with battery back-up.
The input power for the Multi-Power can be realized by connection to an AC/DC supply source
• AC mains supply source : 110...230 V AC - 50/60 Hz
• DC supply source : 10...30 V DC
Automatically a start-up routine is followed, when the 6500W + IMT65W with the Multi-Power is
connected properly to a live AC and/or DC supply. First the DC input is checked and if present
and AC/DC converter active, the power source is DC. When AC power is present and AC/DC
converter active, the power source is AC/DC. If both are not available (interrupted) the internal
dual D-cell battery pack (3.6V - 38 Ah) automatically takes over the power supply.
To save energy, the 6500W + IMT65W will automatically switch to the low power consuming
battery backup mode and will continue to totalize volumes but temporarily stop to transfer the
data.
The Multi-Power unit is IP68 rated and totally sealed and potted to prevent ingress of water.
Therefore the integrated batteries cannot be changed.

To prevent intervention by non-authorised persons to the hardware and software, measures can
be taken after installation and commissioning of the water meter in the field. For detailed
information, please check your local regulations.
The following figures provide an example for additional utility seals. A utility seal on the outer
housing of the signal transmitter and a utility seal on the measurement tube can provide
evidence of an intervention by an non-authorised person.

•
Unit of volume or time
Accuracy of the counters
Multiplier value
Availability of forward and reverse counter and flow rate on the display
The counter values can be programmed to display a higher accuracy with a decimal dot (menu
number 11). The multiplier value enables the display of volumes with more than 8 digits (menu
number 12).
If a multiplier is selected, the multiplier value is shown in the top right corner of the display.
The value on the display must be multiplied with a factor 10, 100 or 1000 to get the actual counter
value.The decimal dot and multiplier value are not available for the flow rate.
The default setting for number of decimals and the multiplier value is 99. The number of
decimals and multiplier are set automatically by the software, based on the following criteria:
•
•
•
•
The meter size and the measurement unit.
The elapsed time to display overflow is minimal 6 years at a flow velocity of 3 m/s.
The number of decimals is as high as possible.
The multiplier (*10, *100, or *1000) can be used only if the number of decimals is zero.

6.3.6 Pulse output
By default two pulse outputs A and B are available. Optionally, status output 1 is available as a
third pulse output C.
The relation between pulse output A and B can be set in menu number 22 to the following presets:
Pulse output A and B; 90° offset (default value)
1 Forward flow
2 Reverse flow
There is a phase shift of 90° offset between pulse output A and B. Pulse output A and B give the
same number of pulses, but pulse output B is shifted half a pulse width in time. In case of
forward flow, pulse output B runs behind pulse output A. In case of reverse flow, pulse output A
runs behind pulse output B.
If after a phase shift (90°) pulse output A runs behind pulse output B, the number of pulses need
to be subtracted from the total, to get the net volume, equal to the sum counter on the display.
Pulse output A and B; Forward - Reverse
1 Forward flow
2 Reverse flow
Pulse output A gives the forward volume and pulse output B gives the reverse volume passing
through the meter. For a net volume, equal to the sum counter on the display, the pulses
provided by pulse output B need to be subtracted from the pulses provided by pulse output A.

7.2 Replacement of the Multi-Power unit
The 6500W + IMT65W can be used with an (optional) external, main supply power pack which is
suitable for pulse output or isolated Modbus.
The Multi-Power provides the necessary power supply for the IMT65W signal transmitter.
An externally supplied voltage to the Multi-Power results in a 4.2 V DC output.
When a main power failure occurs, the internal dual D-cell battery will take over the power
supply to the IMT65W signal transmitter as back up, with a voltage of 3.6 V DC
More information about battery lifetime can be found in refer to Battery lifetime on page 99
The input power for the Multi-Power can be realized by connecting :
• an AC mains supply source; range 110...230 VAC - 50/60 Hz
or
• a DC supply source; range 10...30 VDC

8 TECHNICAL DATA
6500W + IMT65W
8.1 Measuring principle
An electrically conductive fluid flows inside an electrically insulated pipe through a magnetic
field. This magnetic field is generated by a current, flowing through a pair of field coils.
Inside of the fluid, a voltage U is generated:
U=v*k*B*D
in which:
v = mean flow velocity
k = factor correcting for geometry
B = magnetic field strength
D = inner diameter of flowmeter
The signal voltage U is picked off by electrodes and is proportional to the mean flow velocity v
and thus the flow rate Q. A signal transmitter is used to amplify the signal voltage, filter it and
convert it into signals for totalizing, recording and output processing.

Induced voltage (proportional to flow velocity)
Rectangular cross section
Rectangular cross section
The minimal height of the measuring tube decreases the distance between the field coils (1),
resulting in a stronger and more homogeneous magnetic field (2). In addition, the mean flow
velocity v increases due to the rectangular and reduced cross section. The large electrode
spacing (D) and the increased flow velocity results in a higher magnetic signal voltage, also in
the presence of a low flow rate.

8.5 Modbus protocol (option)
The Modbus option on the 6500W + IMT65W is available in two versions:
• not isolated (battery powered) - for standard internal battery version
• galvanically isolated (mains powered) - for the Multi-Power version
The 6500W + IMT65W transmitter and Multi-Power with Modbus has a RS485 interface to
communicate with an external device (PC or other suitable computer system) using the Modbus
protocol. This option allows data exchange between PC or computer and single or multiple
devices. The bus configuration consists of one external device as a master and one or more
signal transmitters as slaves.
For bus operation, the device address, parity, baud rate, stop bits, data format and transmission
delay must be set in the signal transmitter. All devices connected to the bus, must have the same
baud rate and settings, but different (unique) addresses.
CAUTION!
Please note that changing the baud rate will greatly affect the units battery life time. The baud
rate equal to and below 9600 bps are considered energy efficient while baud rates greater than
9600 bps are not.
CAUTION!
Do not use a bus termination for the non-isolated standard battery powered version (will effect
the lifetime)!

8.6 Legal metrology
8.6.1 OIML R49
The 6500W + IMT65W has a certificate of conformity with the international recommendation
OIML R49 (edition 2006). The certificate has been issued by NMi (Dutch board of weight and
measures).
The OIML R49 recommendation 2006 concerns water meters intended for the metering of cold
potable and hot water. The measuring range of the water meter is determined by Q3
(nominal flow rate) and R (ratio).
The 6500W + IMT65W meets the requirements for water meters of accuracy class 1 and 2.
• For accuracy class 1, the maximum permissible error for water meters is ± 1% for the upper
flow rate zone and ± 3% for the lower flow rate zones.
• For accuracy class 2, the maximum permissible error for water meters is ± 2% for the upper
flow rate zone and ± 5% for the lower flow rate zones.
According to OIML R49, accuracy class 1 designation shall be applied only to water meters with
Q3 ≥ 100 m3/h.
Q1 = Q3 / R
Q2 = Q1 * 1.6
Q3 = Q1 * R
Q4 = Q3 * 1.25

8.7 Measurement accuracy
Every electromagnetic flowmeter is calibrated by direct volume comparison. The wet calibration
validates the performance of the flowmeter under reference conditions against accuracy limits.
The accuracy limits of electromagnetic flowmeters are typically the result of the combined effect
of linearity, zero point stability and calibration uncertainty.

8.7.1 6500W + IMT65W without straight inlet and outlet sections
Disturbed flow profiles, such as those that occur behind elbows, tee pieces, reducers or valves
installed in front of a water meter, affect the measuring performance. Therefore it is usually
recommended to fit a straight inlet length in front of and straight outlet length behind a water
meter.
As a result of the unique 6500W flow tube design, whereby the mean flow velocity and flow
profile are optimized within the rectangular and reduced cross section, the additional
uncertainty for upstream disturbances are drastically reduced. Therefore the requirements for
straight length and in front of and behind a meter are reduced.
The NMi has performed tests with various flow and swirl disturbers according to ISO 4064 and
EN 14154. Based on these results the 6500W + IMT65W has received the following certificates:

8.10 Battery lifetime
The maximum battery lifetime depends on the choice of battery, the diameter and on the
measurement interval. Other factors influencing the battery lifetime include the ambient
temperature, the pulse output settings, the status output, the pulse width and the Modbus baud
rate settings. The graphs show the battery lifetime for the different available battery types and
measurement intervals.
Conditions
The maximum battery lifetime is based on default menu and Modbus settings, an ambient
temperature of 25°C / 77°F and a flow rate at 2 m/s. The effect of the optional pressure and
temperature sensor decreases the battery lifetime by 5% (on average).
Maximum lifetime of batteries for: DN25...200 / 1...8"
Figure 8-7: X = Measuring interval in seconds, Y = typical lifetime in years
Maximum lifetime of batteries for: DN250...600 / 10...24"
