1.3 Device description
E-Bulk is an electronic cold water meter. It
measures the ow volume, ow rate and
other parameter values using ultrasonic
technology.The electronic meter continu-
ously monitors the status of operating and
installation parameters. In the event of a
fault, it triggers the dedicated alarms.
The managed alarms are the following: cir-
cuit fault, transducer fault, and air in chan-
nel (see section “Faults and errors”).
The main technical specications of the
E-Bulk design are:
– Liquid crystal display;
– Extremely low starting ow rate. The
minimum ow rate is one third that of
conventional water meters. The device
starts metering water at a ow rate of
10L/h;
– Temperature detection and fault re-
porting. Reporting of abnormal water
consumption and ultrasonic signal quality
detection;
– Absence of moving parts. Resistance to
wear and constant functioning over time;
– Lithium battery. Ensures long-lasting
power supply (13 years);
– Integrated pulse output;
– Available with integrated 868wM-Bus
radio;
– Available with 4-20mA output to meas-
ure the ow rate.

Brown Ground Common
Grey Impulse counter forward
In case of inverse ow, the meter internally records the
volume. When normal ow is restored, impulses are
not generated until the total volume value recorded
previously resets to zero.

1.10.2 Split pulse output
The meter has two pulse outputs which can be connected to two dierent devices.
First output (white wire): pulses are generated regardless of ow direction. When com-
bined with the direction output (yellow wire) it is also possible to distinguish the direction
of ow.
Second output (grey wire): compensated output. In the case of reverse ow, no pulses
are generated and the measured reux volume is compensated before the normal pulse
generation is restored.

1.11 Analogue output 4-20mA (optional)
The 4-20mA analogue output is optional and is used for measuring the ow rate.
The output current varies linearly to the ow rate between 4mA and 20mA.
The 4mA value represents the null ow rate while the 20mA value is the maximum ow rate
(Q4) which varies according to the diameter of the meter.
The 4-20mA output of the E-Bulk is a passive circuit and must be powered by an external
device not supplied to the customer.
Parameter Value U.M.
Power supply 24 VDC
Red wire Positive (+)
White wire Ground (-)
Cable length 3 m
The two-wire analogue output 4-20mA is separate and insulated from the 5-wire pulse
output.

2 Installation
2.1 Receipt of the product
1x
lWARNING!
The instruction manual is an inte-
gral part of the device and should
therefore be read and stored
carefully.
dPROHIBITED
Packaging material must be prop-
erly disposed of and kept out of
children’s reach as it may repre-
sent a hazard. Disposal must be
performed in line with applicable
laws.
2.2 Assembly
Authorised personnel: specialised installer
or plumber, assigned by the metering oper-
ator.
lWARNING!
Only authorised and suitably
trained personnel with sucient
technical experience may install
and operate the device.
Before installing the device, make sure that
the two sections of tube are even to prevent
mechanical stress, clean them with care (es-
pecially in the case of empty tubes) and let
water run for a while, using a stub pipe on
the tube instead of the meter.
If there is no water in the pipeline, open the
valve upstream of the device before install-
ing it. This is necessary because opening
the valve after installation is complete may
cause air suction that could damage the de-
vice.
Before using the meter, rst fully remove air
from the pipe and the device itself. The in-
terception/adjustment valves must be fully
open when doing this. Open the valve at the
start rst and then the valve at the end.

15
Install the meter:
– protected from frost (insulate it if necessary with insulation material) and in the lower
part of the system to prevent air accumulation;
– protected from blows and tampering, where readings are easy to make;
– so that the direction of the arrow on the device coincides with the ow direction.
Install proper interception valves upstream and downstream of the meter to permit main-
tenance operations and inspections on the device, as well as to check the system.
lWARNING!
Before positioning the seal, make sure that it is not damaged.
Make sure that the seal is not damaged during installation.
Make sure that the level of the seal matches that of the tubing.
Check that the seal does not protrude from the tube.
Make sure that the surfaces of the ange are clean and undamaged.

16
– Fasten the meter ange (1) to the counterange (2) using nuts and bolts (not provided)
(3). Make sure that the seal is positioned correctly and that it is level with the ange.

lWARNING!
Make sure that the ange and counter-ange holes are aligned.

17
– Tighten the bolts.
lWARNING!
Check the seal hold to prevent leakage.
The antenna cable (1) is tted with a slot for a fastening screw.
Fasten the cable to a support (not provided) (2) in a vertical position as high as possible to
maximize radio-signal range.
If the meter is installed underground, take the antenna out of the underground space or as
close to the exit as possible. (Only for E-Bulk radio version).

lWARNING!
With metallic closures on manholes, keep the antenna at least 30cm away from
the metal part.

lWARNING!
Sensitivity class in installation conditions: H U3-D0, V U3-D0
Correct meter installation requires a straight length upstream equal to or great-
er than 3 times the diameter of the instrument (H/V U3). Downstream, this pre-
caution is not required (H/V D0).
If the U and/or D letters are followed by the letter S, install a ow straightener.

3 Use
The ultrasonic water meter is ideal for sig-
nicant usage and, thanks to the absence
of moving parts, it is resistant to wear and
grants constant functioning over time.
The measurements taken by the meter are
shown cyclically on the display and they are
also available on other interfaces.
- Data can be transmitted continuously us-
ing the wM-Bus 868MHz radio (optional).
- The pulse output, available as standard,
allows the transmission of pulses for the
metering of the water volume. Various
transmission systems using dierent tech-
nologies can be connected to this output.
- The optional analogue output 4-20mA
makes it possible to measure the ow rate:
it can be connected to a local ow measure-
ment system.
The water meter is not indicated for instal-
lations with especially heavy water, water
with algae or sludge and debris.
4 Conguration
The water meter E-Bulk is supplied with a
default conguration.
The default settings can be changed via:
– The ElecTo Bulk app (Android, download-
able from Google Play Store);
– a Bluetooth or USB optical reading head.
The app allows the following parameters to
be read and programmed:
Impulse outlet
– Pulse duration (1) (default 125ms)
– Pulse weight (2) (100L per DN>100, 10L in
all other cases)
