2. PREAMBLE
General overview
The product is a water meter intended to be installed to count volume of water passing through. It of-
fers measurements of different flow parameters, a CAT-M1 ™ radio with an optional external antenna
connector, an optional BLE interface, an optional optical infrared interface and a push button.
The measurement data can be displayed on the front panel LCD or are also remotely available via op-
tical, BLE or the radio.
The meter pipe can be installed for metrology in whatever direction.The meter will not measure flow
when an empty pipe condition is experienced. An empty pipe is defined as a condition when the flow
sensors are not fully submerged.
The unit of measure and resolution are factory programmed. Options include gallons, cubic feet and
cubic meters.

Sealing
Casing inner seals
The integrity and the inviolability of the meter are ensured by the internal clipping seals and a lead
seal (see position in the Figure 1)
Figure 4 –Example of internal casing seal
The sealing is done by the factory as shown on the above picture. Any tampering suppose destruction
of the the sealing clip and surrounding of the packaging.
Screw cover seal
The integrity and the inviolability of the attachment of the meter can be ensured by one sealable
threading screw. See position in the Figure 1.
Meter connection to water pipes
The water meter is screwed on the water source and distribution pipes using the threading (see the
Figure 1)
Installation of seal over the water source screw is described in above section.
Name plate
The laser marking is only applied on the top cover of the meter.
It is precise, durable, legible and permanent. It is applied without mechanical constraints and without
contact.
The name-plate of every meter contains all information required by FCC and additional information. It
can be seen below:

5. FUNCTIONALITIES
The product supports all the following functionalities.
Metering Functions
The main function of the product is the metering of water volume flowing through it. It measures and
computes all of the values described in this chapter.
All the meters are calibrated and checked in metrology accuracy according to the AWWA. This calibra-
tion and these metrology checks are performed once during the manufacturing process. Thus, there is
no need to re-calibrate the meters during their certified lifetime.
Measurements
Measurements are done using ultrasonic wave and measuring the time for sound to progress in both
flow direction. Those times are processed into the metrologic part to obtain the instantaneous flow.
This flow is integrated over time to obtain the volume flown by the meter.
Assuming the notations: c for sound speed in water, v is the flow speed in the spool piece, L is the ul-
trasonic active measurement path length, Tu and Td are the propagation time for downstream and up-
stream.   

The propagation time difference is then:

The sound speed in water is dependant of the water temperature, so we calculate it out of the sum of
propagation times.    

Once the flow speed is known, the volume noted V is calculated by integration over time based in the
path section S:  
Temperature
The temperature in °C is obtained from the ultrasonic sound speed, using a reversed approximation of
the known Bilaniuk and Wong (1993,1996) convertion of Del Grosso and Mader's 1972 data.

Metrological certified consumption for radiotransport
The meter is able to produce a water consumption data which can be authenticated using a per-device
key. It is possible to retrieve these certified consumption data on-demand over WAN and PAN.
Real Time Clock
A real time clock (RTC) is integrated to the meter which permits to provide all times concerning calen-
dar management and timestamp. The RTC is adjusted at the factory, and could be updated via the
network by the Network System (CS).
Metering volume indicator
The meter has one light-emitting diode (LED) blinking 50 times per liter of water (programmable). See
section 6.4.3
Button
The meter is equipped with 1 push button on the front panel.
It is used to navigate through the different screen and menus.
For this, different push duration are used:

Every record stores the last 60 minutes consumption indexes. To reduce memory footprint, this in-
dexes are saved as a delta consumption.

•Long delay between push and release (> 1.2 s)
•Quick double push and release on button (0.7s)
Details of the LCD menu and information are available below in this document.
Communication ports
All communication ports are protected and requires a proper identification to work.
In case of uninstalling the product from the water pipes and prior to send it by air transportation, un-
sure that you have desactivated all the radio.
Bluetooth Low Energy PAN radio (if product is so
equipped)
The meter can include a local Personal Area Netwrok made by a Bluetooth Low Energy port.
The BLE implementation is Bluetooth ® 5.2 certified working in the 2400 –2483MHz ISM frequency
band and uses a integrated antenna transmitting less than +10 dBm EIRP for short distance communi-
cation only.
This local BLE can be used through a Mobile Phone application to read and write informations into the
applicative part of the device. The BLE range is more than 3 meters and depends of the installation
place and the mobile equipment.
To enable the BLE broadcast, prepare the Mobile App, and push the button of the meter. Within few
seconds, the APP should locate the meter and enable communication. Take care to activate the local
BLE feature before hand if not already done. The access is protected by individual credential.
Note that WAN communication is disabled during the BLE activity. WAN communication is resumed
only once BLE is disabled.
For security reason, the minimal distance to respect between the meter and the human body is 31 cm
(1 feet).
Infrared communication port
An optical port compatible with IrPHY SIR 115.2kb/s could be available. This port can be used to read
and write information into the applicative part of the meter. The access is protected by individual cre-
dential and must be activated.
To reduce power consumption, the infrared is disabled most of the time. A button press must be per-
formed to activate infrared for a 10 sec window. If a communication exchange is detected, the meter
extends the activation timeout accordingly
Remote CAT-M™WAN radio
The Wide Area Network radio communication port is based on a LTE 4G Cat-M1 into the band 4 &13.
