Introduction
1Introduction
The WiMo multiparameter range, including the WiMo sonde (4 locations) and the WiMo Plus sonde
(7 locations), offers flexible and innovative solutions for water quality data collection. The sonde
have a native pressure sensor and temperature measurement and 4 to 7 additional sensors can be
added depending on the model. The end-user plugs directly the sensors to the sonde which are
automatically recognized (Plug and Play system). The sonde can also be connected to a transmission
module that will also be automatically detected.
Data can either be recorded in internal memory of the sonde or transmitted to a data collection
platform via the transmission modems. The sonde also operates in Modbus for real-time
measurement of the environment.
1.1 WiMo Specifications
The WiMo sonde has 4 universal locations where sensors or a cleaning system can be plugged. The
sonde is equipped with a pressure and temperature sensor.
It is powered by 6 Type D Alcaline batteries and is compliant with NiMH Type D rechargeable
batteries. The probe can, if necessary, receive an external power supply
A Wi-Fi link is used to setup the sonde and for file data transfer.
No dedicated software is needed to setup the WiMo. An Embedded WEB Server gives access to all
the sonde functionalities using an internet browser.

Introduction
1.2 WiMo Plus Specifications
The WiMo Plus sonde has 7 universal locations where sensors can be plugged. The central location
can be used also for a wiper instead of sensor. The sonde is equipped with a pressure and
temperature sensor.
It is powered by 6 Type D Alcaline batteries and is compliant with NiMH Type D rechargeable
batteries.

Introduction
1.3 Pressure sensor
The pressure sensor is a piezoresitive sensor that measures absolute pressure. That’s means the
reference is vacuum. The sonde allows adding an offset to compensate the measured pressure with
the current atmospheric pressure in order to get a zeroing of the pressure sensor. However zero will
vary with changes in atmospheric pressure.
The sensor contains its own temperature measurement to make its compensation. Temperature
measurement is available in the WiMo and WiMo Plus sondes.

Introduction
For depth information it is able in the sonde to activate a calculated depth parameter based on the
UNESCO equation.
Pressure measurement is done at the upper tap of the sonde. There is therefore a position offset
between the pressure measurement and the measurements made by the sensors. They don't have
all the same offset:
1.4 Cleaning device
The WiMo and WiMo Plus sondes allow a cleaning device on their location. This device is a smart
wiper. It self-configures according to the sensors that are connected to the sonde. It automatically
detects whether the sensors need or can be cleaned and adjusts its wipe accordingly.
You must take care to avoid having a sensor that should be wiped below the brush in the standby
position.
1.4.1 Installation on a WiMo probe
On version 4 slots (WiMo) the wiper can be placed on any location.

1.4.2 Installation on a WiMo Plus probe
On version 7 locations (WiMo Plus) the position of the wiper is unique and central.
2Operation
2.1 Sensors install
The WiMo and WiMo Plus sondes come with a cap on each sensor location. These caps ensure the
sonde is waterproof. When you remove a cap the sonde is no longer waterproof until you place a
sensor or a cap.
If the WiMo has been immersed in water you must dry the sonde properly before any dismantling.
The plug/unplugged operations of sensors or caps must be done head-down.

Operation
2.1.1 Install/Remove caps
Unscrew the locking sleeve in the anti-clockwise direction by hand or with the key tool provided. Pull
the cap to extract it. Place it on a clean surface and store it taking care not to damage the O-rings.
Before repositioning the cap check that the location in the sonde has no damage and no scratches.
Grease both O-rings of the cap with the grease provided and engage the cap in the location. Screw
the cap clockwise until the locking sleeve is in contact with the sonde head. Help with the key tool
provided if necessary.

Operation
2.1.2 Install/Remove sensors
Unscrew the sensor locking sleeve in the anti-clockwise direction by hand or with the key tool
provided. Pull the sensor to extract it. Place it on a clean surface and store it taking care not to
damage the O-rings.
Before repositioning the sensor check that the location in the sonde has no damage and no
scratches. Grease the two sensor O-rings with the supplied grease and engage it in the location by
making the coded pin coincide with the host hole in the sonde. Take care to the sensor's centering in
its location. Move the sensor slightly from right to left to check that the pin is in front of its
receptacle before starting to screw. Be careful not to damage the threads of the sonde. Any
deterioration of the threads is not covered by the warranty.
