Specially designed to use it in hydrology, the HyMADD allows the monitoring of the level and the temperature of the water, like of its conductivity in the 3 parameters system.
The device is composed of the probe containing all the electronic and of the upper housing including the batteries and the connector for the communication. Small and well integrated, it can be installed really easily and quickly in all situations.
In its basic version, the upper HyMADD-E case of the HyMADD is adapted for 2" piezometric pipes and is fixed with 3 screws. In grey PVC, it looks like a simple tube stopper and remains very discrete. It is enough to unscrew the lid to reach the connector of communication and the batteries, or to do manual measurements through the hole (Ø 16mm) arranged for this purpose.
However, to limitate the risks of vandalism, an aluminium housing was developed to fit inside 2" piezometric pipes and more. Fixed using a sleeve, the HyMADD-I can be protected by a safety-lock cover. In this case, the connector of communication is on the lid, which protects the batteries.
The third version within a rectangular box, the HyMADD-B is available for the assembling in cupboard or on a table.
Thanks to the GPRS option, it is not necessary any more to go ofen on the field to recover measurements, the HyMADD automatically sends the data to your email address as attached file.
Finally, with the Alarm option, 2 threshold levels (ascent or descent) can be programmed and SMS messages will be sent at overruns of these levels.
Differents adaptations like a power supply by a small solar panel are also available on demand (not available for the 3 parameters HyMADD). |
