1. Introduction

This solution is an Ijinus product grouping water height measurement by aerial ultrasonic,

with automatic measurement cycle changes depending on thresholds, flow rate

transformation through conversion tables. Some sensors are equipped with connectors

for coupling with an overflow detector or to control water sampler.

In addition to measuring, these sensors can also be paired with others or serve as data

concentrators (for version with communication 2g, 3g or Sigfox).

2. Three main ranges of measurements (depending on max distance to measure)

LNU0300

Measure up to 3m

LNU0600

Measure up to 6m

LNU1001

Measure up to 10m

External ultrasonic

for example the two figures below show the indication of the diameter of the area that

will be studied by two probes models (3 and 6 m) according to the distance

3. Necessary equipment (4 configuration examples)

a. Temporary Installation

The sensor is autonomous and battery powered (lithium battery), it measures water level by air ultrasonic

waves. It has internal logger and data can be retrieved on-site (by radio using the programming kit : Wiji).

Fixation, either single

or double metal plate

b. Permanent installation of a unique level sensor (continuous monitoring or self-monitoring of

water networks)

For level measurement that is battery powered (replaceable lithium) and send data by GSM/GPRS, 3G (depending on

the sensor).

Sensor integrating a logger, communication GSM/GPRS, 3G modem and its deported antenna

c. Permanent installation of a several level sensors and a logger (continuous monitoring or self-

monitoring of water networks):

For level measurement that is battery powered (replaceable lithium) send data locally by short range radio, and

the logger (LOG0500) retrieve the data of the level sensors and send them by GSM/GPRS.

Communicative logger with its deported antenna and a level sensor

d. Other configurations.

Actually, the communication protocols available for the Ijinus devices are the following:

-Radio for a HF configuration and data retrieval : Wiji protocol

-Wireless communication for remote data monitoring : 2G (for Sms), GPRS, 3G, Sigfox, NB-IoT (LTE-M 3GPP)

-Currently being integrated: 4G, 6LOWPAN

4. Quick configuration with the software Avelour

We will show here the classical version of the system programing, level measurement and data sending by

Gsm/Gprs/3G.

a. Necessary equipment

-The software Avelour in 6.04 version minimum

-Programing Wiji kit or Wiji key

Avelour

Wiji kit

Wiji key

a. Prerequisite

i. The material is considered to be directly functional, the battery can be use directly

ii. All indications contained in this document correspond to programming with Avelour in version

6.04 mini

b. First step : Run Avelour and connect to the sensor to configure

After connection of the Wiji kit equiped with its antenna (or the Wiji key) on your laptop or PC USB port, run the

software Avelour version 6.04 minimum. Click on the button “Connect to a wireless device” then the sensor or

logger will be directly visible by its part number (SN) without the need to activate anything else (ex IJA0101-

0000 3559). Locate the sensor's serial number (SN) on the sensor label and click "OK".

On the first connection with the sensor only the serial number will appear. The following connections you will

see also the name of the installation site or another name that you define.

c. Second step : Selection of the sensor to configure, eventually a firmware update would

be suggested

During its connection with the sensor, the following pop up appears :

When connected, and only if the sensor already has measures in memory, the following options will suggest you

to retrieve the measures:

After your choice of these options, if the sensor is not up to date (case of new firmware developed since your

last connection or you are now connected with a new version of the software Avelour). It is strongly

recommended to read carefully the different messages in the options windows.

The firmware update can last a moment so it is advised to do it while in your office. On-site prefer the best radio

connection (so not if the metal plate of a man hole is closed).

When the sensors is ready, Avelour will look like bellow :

d. Third step : Configuration of Measures part

This part is divided in several paragraphs. Each part will be detailed.

General informations

This part is useful to describe the measurement point. The most important information would be the name that

will help you to find your sensor at a future connection.

Measures

Choice of the application to configure

This part is the most important, it allows you to configure your sensor.

First of all, and the simplest click on the button “Add”, then choose “Water height”.

Choice of the measure period

In this new menu, select the period you want the sensor to measure (in this example every 15min)

To the right of the measure period selector, 2 little icons allowing a deferred programming according to the

time period and day of the week you can choose from. So far the sensor is not calibrated.

Calibration of the water height

After clicking the calibration button the bellow windows appears:

It is difficult to establish rules but globally 3 cases may arise:

CASE 1 : Ideal case: unique echo (test in lab or if the sensor front flat water surface for example)

A simple calibration would be possible.

CASE 2 : Case of a classic man hole with at the bottom an invert. The figure bellow shows two echoes (the

invert and the water). A calibration in advanced mode will be possible. First check that the sensor is well

positioned, fronting and perpendicular to the water.

CASE 3 : Complex case

the presence of many echoes make difficult the calibration the easiest way. A priority should be to move the

sensor if possible otherwise go to the expert mode. (Only for experienced users).
