Installation instructions
Ultrasonic water meter
ElecTo Bulk
Important
Before installing the meter, please read this manual carefully.
This instruction sheet is for qualified technicians and does not contain the basic installation instructions.
The design and specifications of the meter may change and may not correspond to the description contained in these
instructions. In this event refer to the meter. These changes do not affect meter operation. For information contact the
manufacturer.
ElecTo Bulk is a precision instrument. Before leaving the factory it undergoes strict tests and is intended to be used by
qualified personnel.
If the meter fails to operate properly or requires repair, contact the manufacturer or an authorised dealer.
Do not shorten or lengthen the cable. This might affect meter performance.
The meters undergo strict tests before leaving the factory. Maintenance, replacement of components and calibration
must be carried out only by qualified personnel.
Contact the manufacturer for technical support.
In the event of loss of measuring data due to malfunction or other causes, the manufacturer commits to recover the
data. The manufacturer undertakes no responsibility if the loss of measuring data is caused by the user or by failure to
back up data.
The meter may be provided with a built-in pressure sensor for pipe pressure monitoring (optional).
Choice of the water meter
Before installing the meter ensure that the nominal diameter, nominal flow rate, working temperature and pressure are
compatible with the operating conditions.
Transport and storage
Water meters are precision instruments: handle with care and protect from shocks and vibration.
Store the meters in a frost-free place. Defrosting of the meter is a delicate operation.
Store the meters in a dry place, at a temperature between 0 °C and +50 °C. Do not expose to direct sunlight.
Recommendations for the installation
Before installing the meter check that the two pipe sections are aligned in order to avoid mechanical stress. Clean the
two pipe sections carefully (especially if the system is empty) and allow water to flow in the pipe for some time using a
pipe section instead of the meter.
If there is no water in the system, open the upstream valve before installing the meter. This is necessary to avoid
negative pressure from building when opening the valve at the end of the installation procedure because it might
damage the meter.
If the meter is installed in vertical or inclined position, the pipe must always be full of water.
Install the meter where it will be safe from frost (if necessary protect the meter with insulating material) and possibly in
the lowest part of the system to prevent air from building up.
Install the meter in a place where it will be protected from tampering and impact, and where it can be read easily.
Install the meter ensuring that the flow direction arrow on the body points in the same direction as the flow.
It is advisable to install a valve upstream and downstream of the meter in order to enable maintenance and verification
of the meter and monitoring of the system.
Operating conditions
Temperature class: T30/T50
Admissible pressure (MAP): 16 bar
Straight pipes and flow straighteners
For the usage of upstream and/or downstream straight pipes refer to the letters U and D marked on the dial. If the
letters U and/or D are followed by the letter S, a flow straightener must be installed.
Battery
The battery has a service life of 13 years. It is recommended to replace the battery before it is completely discharged in
order to avoid malfunction.

Installation procedure
1. Counter flange
2. Bolts
3. Meter body
4. Flange
Position a gasket on each flange.
Connect the meter (2) to the pipe. Ensure that the flow direction is
correct.
Position the meter's flange (4) on the counter flange (1) and tighten it with the bolts provided (3). Ensure that the
gasket is in the right position and in line with the flange.
Tighten the bolts.
Before positioning the gasket ensure that it is not damaged. Ensure that the gasket is not damaged during the
installation. Ensure that the gasket is in the right position and in line with the flange.
Ensure that the gaskets are tight to prevent leaks.
Ensure that the gasket do not protrude from the pipe.
Ensure that the flange surface is clean and is not damaged.
Ensure that the bolt holes of flanges and counter flanges are aligned.
Liquid crystal display
The meter has two menus: a primary menu (standard) and a secondary menu (with details)
To move from the primary menu to the secondary menu use the reading software.
The primary menu has a standard mode and a single screen view mode.
To move from one menu item to another press the magnetically operated button using a magnetic pen.
The magnetically operated button is indicated by this pictogram:
